This is part three of a three-part series. If you haven't listened to part two yet,
make sure you do before you listen to this episode.
The final part of the Mr Big Sting involving Dennis Cheeseman started off like this. Nick
told Dennis that their big crime boss had noticed his work and had requested his attendance
in Edmonton. This was apparently a big deal. Dennis was to buy a whole new outfit to look
the part paid for by the RCMP. He was chuffed with his new look and commented that he'd
like to dress like that more often. Before going in to see Mr Big, Dennis was advised
that the way to win his favor was to be upfront and honest.
After some icebreakers, Mr Big asked Dennis for the real story of what had happened at
Marathorpe, promising him that they would take care of it. But Dennis gave them yet
another version. When Mr Big called him on it, Dennis admitted that it was hard to tell
the truth, but he trusted them so he would. But he just gave them another version of the
story, one that had been scrubbed of any mention of Sean Hennessey's involvement. Dennis said
that he drove the truck and Roscoe asked him what he thought he was going to do with
the rifle. Dennis replied, you're going to take care of business.
As they arrived at the spot nearby Roscoe's farm where he said they wanted to be dropped
off, Dennis said they could hardly see the cop car lights on the property. Then Roscoe
got out, Dennis drove home and that was it. Dennis told Mr Big that that was all he knew.
Mr Big thanked him for being honest and Dennis said he was sorry for lying. Quote, I'm not
a saint, but I didn't want that to happen. But the RCMP now had much to think about.
There were questions about Dennis' culpability. David Staples from the Edmonton Journal analysed
the situation as part of his long-form series on the case. Quote, If Dennis Cheeseman knew
before the mass murder about Roscoe's intent to kill, especially if Roscoe had clearly
spelt it out in his own words, then Cheeseman was surely guilty of first-degree murder for
helping Roscoe and failing to warn the police of his presence. But if Cheeseman didn't know,
if he had only figured things out the next day as he was here suggesting, the verdict
might well be different in any future trial. The piece in the Edmonton Journal went on
to say that in all of Dennis' previous statements to RCMP investigators and undercover agents,
his confessions regarding Roscoe's intent had, quote, the flavour of a man who realised
only after the mass murder had happened that homicide was definitely Roscoe's plan all
along. The other issue for the RCMP was that Dennis' confession hadn't mentioned Sean
Hennessy, and even if it did, it couldn't be used as evidence against Sean because
that would be hearsay. A plan was starting to form where Sean would need to be looped
into the crime gang in a different way. The gang managed to convince Dennis that satellite
footage existed of him driving Roscoe that night, but they had contacts that could erase
the footage if he needed it. All he needed to do was tell them the truth of what happened
that night and they could take care of it. Obviously this was fake, there was no satellite
footage, and it was so easy. Dennis immediately realised that Sean would be captured on the
footage too and admitted the truth about the fact that they were both in Sean's car and
Sean was the one driving. He told them that Roscoe had gone to Sean first to demand help
and it was Sean that had looped him in. Dennis said he was so scared that he did whatever
he had to, but this time the language was softened on whether Dennis knew that Roscoe
intended to kill police. He said that the only thing they knew was that Roscoe was set
on returning to the property. The RCMP still had no idea whether Dennis actually knew that
Roscoe had intended on killing the Mounties, and that intent was everything. At the end
of the conversation, Mr Big assured Dennis that all was well and thanked him for coming
clean. Dennis then asked if he could ask a question. He'd been thinking about it and
if there was a satellite image out there that showed him and Sean in the car with Roscoe,
then wouldn't the cops already have it? Mr Big replied, I don't know, maybe they already
do. It seemed Dennis Cheeseman was frequently underestimated.
It was time for the RCMP to loop Sean Hennessey in. The other sting operation with the welder was
still lying dormant and it was time to resurrect it with a new plot point. The welder called Sean
out of the blue and told him that he'd been ambushed by the RCMP on the highway and interrogated
over their friendship and Sean's possible involvement with the Marathorpe tragedy. And what
do you know, he'd recorded the conversation and had it right there for Sean to listen to.
According to the Edmonton Journal, Sean still suspected that the welder might be an agent
of the RCMP. Skeptical, he asked him why he recorded the conversation and the welder said
he always tapes conversations with the cops. Sean apologized for causing the RCMP's intrusion
in the welder's life anyway and then they listened to the tape. Sean had been cool,
calm and collected whenever he'd spoken about Marathorpe, but all this changed when he listened
to the secret recorded tape of the welder's conversation with the RCMP. Of course, it was
obviously a staged performance but it sounded real enough. At the end, Sean suggested that the
welder take the tape to his own lawyer but then he could not contain his anger. He added,
that's all they do, they lie and lie and lie and lie. You're supposed to be the RCMP,
you're supposed to be the law, you're supposed to be the truth, but instead they're acting like
a bunch of criminals themselves coming in and ruining lives. The welder saw an opportunity
to get Sean to open up to him about Marathorpe and said he could totally understand why people
might want to keep things from the RCMP. Sean spoke of his anguish about how his family had been
affected, how the RCMP had spread rumors about him at his mother's workplace and to his friends.
He said Amounti had told him that the only reason they were convinced he was involved in the grow-up
was because Roscoe's mother Stephanie had told them that he was a partner. Sean said that the
Amounti also told him that they believed he stole vehicles for the chop shop which he personally
was shocked to hear. He said he works 11 hours a day and they think after work he's stealing
vehicles to take to a chop shop? Quote, get real. He said he refused to let Roscoe park his truck
on the property but he didn't know anything about his criminal past, the sexual assaults,
suspected murders, violent behavior and grooming stalking and threatening of young men.
Roscoe had a reputation in Marathorpe but not in Barhead. Sean told the welder that in another
conversation with the RCMP investigators they told him that they had found explicit photos of him
at Roscoe's house as though Sean was one of his victims. Sean protested loudly, quote,
don't give me that bullshit, I know you're lying. He told the welder about how many of his friends
and other people in and around Barhead had turned against him and how difficult life had become.
The welder pointed out that there must be some connection there for the RCMP to focus on him
so much. Maybe it was the rifle. How did Roscoe get the rifle from Sean's grandfather? Sean said,
how stupid do you think I am to give him the gun? Sean then told the welder another cover story
which was that he thought Roscoe had a third party steal the gun for him, quote,
because there's a gun at his place registered to my grandfather I'm guilty, guilty until proven
innocent. He said it was bullshit and not justice at all, quote, they can dig and dig and dig and
dig some more. Obviously Sean did not have good words to say about Roscoe either. He referred
to him as a criminal mastermind who screwed him and ruined his family's life by pulling him into
his situation that night. Sean told the welder that was all that happened. He didn't do anything wrong
and it was the welder's choice whether to believe him or bail on him like everyone else.
The welder reassured him that everything was fine and then after Sean left he stashed away the
glass that he'd been drinking from. The RCMP would get their DNA sample.
Back with Dennis Cheeseman the gang of undercover RCMP agents were hoping that he would somehow
be able to rope Sean Hennessy in and they would try to get the truth directly from the horse's mouth.
But Dennis was starting to grow wary of the gang. He liked the money and the comradery but he did not
enjoy the high pressure of the lifestyle. For example he'd recently been asked to hunt down a
sex worker and her client and take photos of them together to be used as blackmail. They were of
course all undercover RCMP agents and Dennis performed the task. While he seemed upbeat and
proud afterwards his family were starting to notice a change in him. He seemed tense and
worried. His mind always seemed to be somewhere else and he was doing things he had never done
before. He was close with Sean's sister Alicia and one day when they were talking she asked him
if he was running drugs for the gang. Dennis scoffed at that but in another conversation
his sister Christine asked him if he really knew who his business associates were
and he said he thought they might be hell's angels. According to a close friend of Dennis's
called Rob, his new friends had made him nervous and he wanted to get out of the gang but they
kept persuading him to do one more job. The gang continued with their plan to concoct a story
whereby Nick, Mary's high school friend, the one who brought Dennis into the gang,
claimed he too had been interrogated by the RCMP about the Mayer Thorpe tragedy.
And then the crime gang complained that all of this entanglement put their crime organisation
under a microscope and was now affecting their ability to get their jobs done and earn bank.
The RCMP's new scheme was that Mr Big would fly into Barhead and Dennis would bring Sean
to meet him. Then they would talk about the predicament they were in and see how Mr Big
could make it all go away with his immense power and influence and hopefully Sean would confess.
Dennis managed to convince Sean to meet with the Mr Big character at the airport.
He was given a specific car to drive by the gang, a car that neither of them knew had been bugged.
As soon as Dennis and Sean got in the car Sean declared this is fucked and said he suspected
they were all cops but Dennis assured him that the gang would help them get out of their predicament.
The plane arrived and Sean and Mr Big had a chat, just the two of them. The undercover agent
playing Mr Big was a man who carried himself with authority and who the rest of the gang had
already demonstrated that they revered. He told Sean that he had a big problem but there was a
way to work through it. He added that Dennis had already told him exactly what happened in Marathor.
Sean was surprised, he did? Mr Big mentioned the satellite footage that would show who was
driving the car. This time he added that he had it on good authority that the RCMP did not have
the footage yet and while he hadn't seen it himself he knew that people could be seen getting out of
the car and he had a license plate which of course matched to Sean's car. Sean was shocked.
Mr Big then told Sean just to tell him the truth. He'd known men who had probably done much worse
than whatever it was that Sean had done but he couldn't help him unless he knew the full story.
Sean replied that he was hesitant. After all this was just a guy that had shown up in an airplane.
Mr Big then said he wasn't asking for a confession, he just wanted to know if what Dennis told him was
true. Sean was still hesitant to answer but after more prodding he opened up about Roscoe.
Quote, the guy came into my house man. He said that Roscoe threatened him saying that because
he had helped with odd jobs on the property and had sold some cannabis to friends and family
that he would be implicated and had to help. He said that he felt he had no option but to help
him do whatever he was going to do. Mr Big asked Sean about the rifle. Sean said that Roscoe demanded
it and again he didn't feel he had an option and he said he didn't know about any plans Roscoe had
other than the fact that he wanted to burn down the Clonset hut. Quote, that's all he told me
he was going to do. He told Mr Big that he wiped the rifle down before giving it to Roscoe just
in case. Quote, he told me he had no intentions of using it, none. Sean said the only reason he
did what he did was to get Roscoe out of their family's home as fast as he could. At the end,
Sean said you just got a full confession dude and with that Mr Big waved all that fake satellite
footage away. In the meantime the forensic results had come back from the glass that Sean had been
sipping from. As you remember after the Marathon tragedy they found what they believed to be Roscoe's
hiding spot in the Clonset hut. There was a sheet there, a pillowcase, a pair of work gloves,
a small bottle of water and a tin of bear spray. Sean's DNA was matched to the DNA on the work
gloves. The RCMP had what they needed to press charges and within two days two arrests were
made nearly two and a half years after the Marathon tragedy. Dennis Cheeseman was arrested first
reportedly by the same undercover officers he'd grown to regard as his crime gang friends.
Next it was Sean Hennessey's turn. Friends of Sean and Christine would tell CBC's the Fifth
Estate all about Sean's arrest because they ended up being dragged into what would become an
unnecessary spectacle. The night before Sean was arrested he and Christine had enjoyed a
social Saturday night at the rural home of their friends Kathy and Grant. They had a great night
and then the Hennessey family returned home. But the next morning Kathy and Grant were awoken by
helicopters overhead and an armed RCMP squad in camouflage riot gear in their front yard,
pointing their rifles and telling the couple to stop and tell them where Sean Hennessey was.
Grant and Kathy told them repeatedly that this was not where Sean lived and he was not there
but the squad didn't want to hear what they had to say. The couple were detained on their driveway
terrified knowing that their two young children were still in the house. They could do nothing
but watch helplessly as the RCMP squad marched into their home pointing their rifles around as
they searched each room including at the children. Kathy would tell the Fifth Estate that leaving
the little ones in the house was the worst mistake they ever made. Obviously she couldn't
have known that their safe haven would be invaded by the RCMP. Before long the Mounties realised
that they had swarmed the wrong house. Before they left they warned the traumatised family
not to contact Sean. The squad team then located Sean at a family gathering and moved in making a
big show of pinning both him and Christine to the ground. Neither of them resisted or fought back.
Sean Hennessey and Dennis Cheeseman were charged with four counts of first degree murder in the
deaths of constables Anthony Gordon, Leo Johnston, Brock Myroll and Peter Sheeman. The arrests were
described as a very significant breakthrough for the force. The media reported that the RCMP had
spent more than two million dollars investigating the Marathon tragedy deploying between 40 and
200 officers. But people still had no idea what had happened. It was reported that neither Sean
nor Dennis were actually on the Roscoe farm the day of the tragedy. Everyone was puzzled.
It was announced that the Alberta government had called a fatality inquiry to look into the
tragedy but that wasn't able to get started until the case against Sean and Dennis had gone through
the court system. Do you have a passion project that you're ready to take to the next level?

In the meantime the RCMP had conducted their own internal review into their actions that day.
The force was on the end of some damning criticism that was growing louder. Retired RCMP
superintendent Clyde Kitteringham had described the RCMP's handling of the tragedy as a failure,
the result of negligent supervision. He stressed to the CBC that the four Mounties who lost their
lives were junior constables just following instructions but given Roscoe's reputation,
those in charge of issuing those instructions should have made more of an effort to find out
where Roscoe was before sending junior officers to the scene and if that wasn't possible they
should have brought in a tactical team to secure the perimeter before the search. Kitteringham
told CBC that he wasn't alone with this thinking but people inside the RCMP were being told to
keep quiet or risk losing their jobs. In response to these comments an RCMP spokesperson said the
former superintendent did not have all the facts of the situation but when the findings of the
internal review were eventually leaked it disappointed even more people. It concluded quote
Roscoe was not identified as posing a deadly threat to police prior to the shooting. While he
was well known to police his behavior was not consistent with someone who would be considered
a deadly threat to officers. There was nothing available to the police at the time which would
have suggested that Roscoe had intent to plan and execute a deadly assault on officers. Many
pointed out that elsewhere the report states that the tragedy was a premeditated act of murder
but also that Roscoe's behavior was unprecedented and unanticipated. The report suggested that
understaffing at the Marathorpe Detachment may have played a part in the tragedy. The
detachment only had 12 members and experienced frequent staff shortages and that's why junior
officers with less than five years experience were sent over including Constable Anthony Gordon
who was borrowed from the White Court detachment because Marathorpe simply had no one else and
during that night several of them worked longer shifts than they should have. The next morning
when no one was available to drive Constable Brock Myroll to the Roscoe property Constable
Peter Sheeman volunteered to do it and he received approval from his supervisor even though he was
unarmed and without armour. Many RCMP officers were not happy with the outcome of the internal
review and the lack of transparency on what really happened that day. Then Constable Rob
Creaser bravely spoke out to the media about his disenchantment with the RCMP saying that he
learned more about what had happened at Marathorpe from the Fifth Estate's investigative documentary
than from his own organization and he felt that was a tragedy too. He said that when he first spoke
out to local radio about the issue he had his knuckles wrapped by the RCMP and was ordered not
to do it again but he did and today he is no longer a member. Retired RCMP officer Mike Statenick
the one who had told his nine-year-old daughter to shoot Roscoe if she saw him spoke out again.
He said that the four Mounties who had died that day were only doing what they were told
and the RCMP's internal investigation was inadequate. This was a potential learning
experience he said where RCMP members could learn what had happened and make sure it didn't
happen again quote but instead they haven't learned a thing. It was also pointed out that
the Federal Human Resources report which is mandatory every time someone dies on the job
was just a verbatim regurgitation of the RCMP's report. They hadn't even interviewed the two
constables from the Auto Theft Unit the only living witnesses to what happened.
Former RCMP officer Rob Creaser told CBC that he was concerned that RCMP leadership had avoided
saying anything because that might open them up to criticism and they might get sued.
It seemed that all the RCMP was trying to do was protect itself.
As Dennis Cheesman and Sean Hennessy waited in jail for court proceedings to start,
the community was divided. On one side the families of the fallen four officers communicated
that they were happy to see the arrests but on the other side there was a good deal of community
support for the two men too. After eight months Sean applied for bail and over a hundred letters
were presented to the court in support of his character. He was described as generous, helpful,
a loving husband, father, brother, son and friend and a respected employee. Two of the character
statements were from two former RCMP officers who said they enjoyed a good relationship with Sean,
he never caused them any problems and neither he nor Dennis fit the role of murderer. Sean
was released on bail after eight months and Dennis the month after that. Both had to abide by strict
conditions including that they go to work every day, observe a curfew and not talk to each other.
As you'll remember Roscoe's mother Stephanie Fiffield originally identified Sean Hennessy as
being a partner in the cannabis grow-up and told the RCMP that Roscoe grew the weed and Sean sold
it. It was this statement that convinced the Mounties that Sean had the motive to help Roscoe
burn down the Quonset hut that night. But in May of 2008 Stephanie contradicted this statement at
the preliminary hearing where she testified about her knowledge of what was going on at her son's
property. When asked on the witness stand if she knew Sean Hennessy she replied,
no I don't, I've never met the man and I've never seen him before and I've never heard his name
before. This statement was consistent with what Sean had always said, he'd never seen Roscoe's
mother and he'd never even been inside the Quonset hut. On the stand Stephanie testified she knew
nothing about any cannabis grow-up or chop shop on her son's property and insisted it was the RCMP
who had thrown the Hennessy name to her and the prosecution never produced any evidence that Sean
Hennessy was even a minor partner in the operation and there was speculation that perhaps Stephanie
had made throwaway comments early on to divert the attention away from her son and her family
so when the RCMP mentioned the Hennessy name she jumped on it but later when she realized the
impact of her statement she tried to take it back. Regardless the case was cleared to go to trial.
James Roscoe's mother Stephanie and her last husband Warren Fiffield would both die in a
car accident about five years later. The CBC's the Fifth the State documentary reported that in
the lead-up to the trial the RCMP applied increasing pressure on Sean Hennessy and Dennis
Cheeseman to plead guilty that is after all the goal of the Mr. Big Sting. They'd spent up big on
the investigation and the best possible scenario was to tie it all up in a guilty plea and save the
further expense of a trial. According to Sean Mounties asked him to watch videos of the four
fallen families as they each described the loss of their loved one. If a tug on the heart strings
wasn't enough to inspire them to plead guilty the RCMP knew they were completely broke from all
their legal bills and couldn't afford a trial defense and even though neither Sean nor Dennis
had any prior criminal record the RCMP told them that the severity of the crimes they'd been charged
with coupled with the public interest in the case meant they could be facing serious jail time if
they were found guilty at trial likely consecutive life sentences. It worked in January of 2009
29 year old Sean Hennessy and 25 year old Dennis Cheeseman decided to plead guilty to four charges
of manslaughter. The night beforehand Sean sat down for an interview with CBC's the Fifth the
State along with his wife Christine. He said he was going to plead guilty because he wanted to move
on with his life in a way that would have him back with his family the soonest. He couldn't
risk a life sentence and he had no faith in the justice system and also he did feel partially
guilty for what happened. In the agreed statement of facts presented to the PACT courtroom Sean Hennessy
and Dennis Cheeseman admitted their roles in driving Roscoe back to his compound and giving
him a rifle and ammunition although it had been determined that the Hennessy rifle was not used
to kill any of the four officers. Because Dennis and Sean were forbidden from talking to each other
the agreed statement of facts appeared to have been a merged document consisting of an amalgamation
of Dennis's various confessions and both of their stories as told individually to their lawyers.
The statement was described as vague when it got to the part about intent
about whether they knew what Roscoe was going to do that night. It seemed to boil down to this
quote Sean and Dennis knew that armed confrontation with the police was a real possibility and that
the situation was clearly trouble. There would be some dispute of this later.
As the statement of facts was read out the families of the fallen four officers wiped away
tears. The two men were given the opportunity to address the court. Sean apologised for his
involvement quote I am truly sorry for the loss these families have suffered in no way did I
mean for any harm to come to anyone. Dennis the man who so desperately wanted to save his brother
in law that he talked himself into a hole had obviously learned a lesson when asked if he had
anything to say he stated that his lawyer had already said everything for him in court.
The families of the fallen four officers submitted victim impact statements where they
described the immense mental and physical impact of their loss constable Brock Myrol's father Keith
described his never-ending overwhelming grief. He looked at Sean and Dennis as he said quote
I don't know how else to tell you your actions ruined my life I'm suffering and I don't see an
end in sight. Brock's fiance Angela told court that she'd lost her soulmate and had contemplated suicide.
Constable Peter Sheeman's father Reverend Don Sheeman said words cannot begin to describe the
devastation the family felt that day. Peter's younger sister Julia said that it breaks her
heart to know that her child will only get to know Uncle Peter through stories and pictures.
Constable Leo Johnston's mother Grace spoke directly to Sean and Dennis quote how could you
what were you thinking or not thinking to be associated with someone like Roscoe
and constable Anthony Gordon's wife Kim said Anthony was robbed of seeing the birth of his second
son and because of the events of March 2nd and 3rd Spencer AJ and I will miss our lives with Anthony
forever. As these statements were read Dennis was observed to be crying Sean was described as
emotionless but solemn. At the sentencing hearing Justice Eric Macklin read out his decision.
He told the court that Sean was the guilty party of the two with moral culpability that was quote
as high as it can be for an individual who did not premeditate a murder was not at the
scene of the murders and did not fire a gun. Although Sean was under duress the judge determined
that his principal motivation was to destroy evidence of his involvement with Roscoe's cannabis
grow up. Dennis was described as little more than a bystander and even though his involvement came
from a fear of Roscoe combined with his desire to support his brother-in-law Dennis still agreed to
assist Sean knowing that Roscoe planned to at least commit the unlawful act of burning down the
Quonset hut. The judge said that regardless of whether they were afraid Roscoe would seek revenge
quote a phone call warning police that he was on the property and armed would simply have allowed
them to properly meet the situation. When it came to sentencing for four counts of manslaughter the
defense lawyers asked for less than five years saying neither of the two men wanted the event to
happen and neither of them shot the officers. The prosecution wanted a sentence of between 10
and 15 years and that's pretty much what they got. Justice Macklin's sentence Sean Hennessey to 15
years and Dennis Cheeseman to 12. With credit given for pleading guilty and time already spent in
custody Sean's sentence was reduced to nearly 10 and a half years and Dennis's to just over seven.
Justice Macklin then spoke about the severity of the crime calling an attack on a police officer
an attack on society itself and the sentence appropriately reflects that. He then referred
to the fallen four officers quote these four men were Canadian heroes and will be forever remembered
as such. Outside court their family said they were satisfied with the sentences
but the families of Dennis Cheeseman and Sean Hennessey were not. They spoke out to the media
saying they thought the sentences were far too long for the crime and it didn't represent justice
as far as they were concerned. They alleged that Sean's lawyer failed to investigate a key witness
although no further details were reported on this and also that he pressured Sean to plead guilty by
suggesting there would be dire consequences otherwise. In response to this public criticism
Sean's lawyer said that he was satisfied that he had discharged his professional obligations in the
case. A week after the sentencing hearing CBC aired the fifth the state documentary that was filmed
the night before Sean and Dennis pleaded guilty. This was the first interview that Sean had ever
given and his wife Christine was by his side. Both of them choked back tears as they spoke
knowing that by the time the documentary aired Sean would be back in prison. He was asked if he
knew what was going on in the quonset hut and he said yes quote I knew he was growing marijuana
and on numerous occasions I had acquired marijuana from James Roscoe and sold it for him. When the
reporter Lyndon McIntyre expressed surprise at this Sean said he knew it was an illegal act and
something that the public wasn't going to look too kindly at. It should be noted that Sean never
admitted to being a partner in the operation though and there was never any evidence that he was
but the fifth the state pointed out that whatever his involvement it clearly gave Roscoe leverage
which he used when making his demands. Sean said that all Roscoe had told them was that there were
bailiffs on the property earlier and he wanted to use the Hennessy rifle to shoot gas tanks and
burn down the evidence of the marijuana grow-up in the quonset. He said he had no idea that
Mounties were there. At this CBC journalist Lyndon McIntyre furrowed his brow and brought up the
fact that in the agreed statement of facts Dennis said Roscoe was ranting and raving about the RCMP
on the ride home referring to it as devil talk. In response Sean said that he was shocked to hear
the versions of Dennis's story where he said Roscoe told him he'd planned to kill Mounties.
Sean said he was there too and there was no talk of Mounties ever from Roscoe. Sean added that he
didn't even think Roscoe himself knew what he was about to do other than going home and burning
his dope. Christine said she'd asked her brother why he said those things and his only explanation
was that he thought his new crime gang was the mob and he told them what they wanted to hear.
She added they didn't realize he said it out of fear.
It was also pointed out that according to the agreed statement of facts
Sean and Dennis saw the police car lights on the property from the spot where they dropped
Roscoe off. But in this fifth the state interview Sean said that wasn't true. The only lights he
could see were one set of headlights and the lights inside Roscoe's mobile home. He didn't see any
flashing red and blue lights. The documentary did not show any follow-up on why some of his
comments to the fifth the state contradicted the agreed statement of facts he'd signed.
Although as he'd stated earlier in the interview he felt pressured to plead guilty from multiple
directions and just wanted to move on with his life so perhaps the answer is as simple as that.
Sean was asked why he didn't go forward to the RCMP the next day after he'd learned
everything that had taken place. He said that he was in a totally different state of mind
and thought it would blow over if he just laid low for a while. But he still felt some level
of responsibility for driving Roscoe home. Sean paused as he composed himself before adding
but at the same time I only did it in fear of my family.
Sean and Dennis's bail conditions forbade them from speaking to each other and it was clear that
there was now painful distance between what was once a happy blended family. Sean and Christine
told the fifth the state that they were not angry about what Dennis had said. Christine said if she
put herself in her brother's shoes she may have made a different choice but she could see why he
said what he said. After the contradictions between the agreed statement of facts and the CBC
fifth the state interview were reported on by CBC News a leading expert in Mr Big Sting's
criticised the confessions Sean and Dennis gave to Mr Big. Forensic psychologist Tim Moore told
the Edmonton Journal that the Mr Big technique is unprecedented in terms of the degree of manipulation
and invasion of privacy and the result in this case was that both men said different things on
different occasions to different people for different reasons over a two-year period not
exactly high on the reliability meter. The month after the guilty plea it was revealed that Dennis
and Sean had been sent out of the province of Alberta and were each serving their sentences
in separate high security prisons. A parole officer named Jay West had been appointed to spend
dozens of hours interviewing and assessing them after their guilty pleas and he spoke out about
his grave concerns. He didn't see how the decision to separate them both and place them so far away
from their families was founded on sound policy or what it was expected to achieve. The authorities
responded by saying that the decision to separate them and send them out of province
was necessitated by the high-profile nature of their case and was designed to make everything
less stressful. Parole officer Jay West described them as victims of both James Roscoe
and of a misguided witch hunt by the RCMP who had been deprived of their pound of flesh when Roscoe
killed himself.
As you'll remember in the months before the Marathorpe tragedy Christine had noticed that
something was off with her brother Dennis and he was even more closed off than he usually was.
After the guilty pleas the Edmonton Journal's long-form series on the case reported on Dennis's
conversations with his boss Brad where he confided that he'd been sexually assaulted at gunpoint.
Barry Hennessey spoke out on Dennis's behalf since the siblings had essentially been orphaned as
teenagers. He wrote to then Prime Minister Stephen Harper asking for help and blasting the RCMP for
failing to treat Dennis like a victim of sexual assault. He said even though the force knew what
Dennis had alleged about Roscoe they launched the expensive sting operation on him anyway.
Barry pointed out that he was suicidal at the time and very depressed and if Dennis were a woman
the undercover operation would have ended very quickly after he confided in his boss.
In this letter Barry revealed that Dennis had since confided in his daughter Alicia about the
incident too. The Edmonton Journal would later report that Alicia had seen some of the crown's
evidence which included a booklet of photos that Roscoe had taken of some of his sex assault victims
all young males. It was a trophy of sorts. When Alicia visited Dennis in jail and mentioned
her shock when she saw the photos she was surprised when he grew quiet and choked up.
When she asked him to explain all he would say was quote he did bad things to me that no one ever
knew about. Dennis still wasn't ready to talk about it but over the next few meetings he confided
in Alicia that Roscoe had a gun and held it to his head forcing him to submit to the sexual assault.
The same story he'd told his boss. This news devastated the family. According to the Edmonton
Journal Dennis refused to speak publicly about the assault perhaps even refused to testify to it
which may have been the reason it didn't come out in court but his family reported that while he
didn't want to talk about it he was now okay with the public knowing the details.
Sean Hennessey got a new lawyer Hirsch Walsh known for helping free David Milgaard from prison
after he'd been wrongfully convicted of raping and murdering nurse Gail Miller in 1969 a very famous
case. About Mayer Thorpe Walsh told the media that he sees people who commit serious crimes not
getting the kind of sentence that Sean Hennessey got. He added a reasonable person cannot be expected
to predict the actions of a madman. The prosecution's case had always been that because Sean and Dennis
knew Roscoe they should have known what he was capable of doing and should have stopped it but
Sean's new lawyer argued that RCMP officers who were also familiar with Roscoe should have been
better able to predict his behavior so why would Dennis and Sean expected to know and do what senior
Mounties could not? It made no difference both men appealed their sentences and both appeals were
unsuccessful. The decision stated that the sentences were appropriate for the worst
such crime in Canadian history and that Roscoe probably would not have succeeded in killing
the Mounties without their help. The public fatality inquiry into the Mayer Thorpe tragedy
was held in 2011 presided over by Judge Daniel Powell. The goal was not to assign blame but
to figure out what happened and make conclusions on how to prevent it happening again. The key
question was whether the RCMP adequately assessed the threat posed by James Roscoe and whether
they took the appropriate steps to keep their members safe. A number of people testified and
gave statements including some emotional submissions by the family members of the fallen four officers.
It was concluded that Roscoe fired 16 shots during the ambush and 11 of them hit the four
constables. Death was quick something that gave their family some comfort but the medical
examiner testified that there was no way to know how much pain the four officers suffered
or who was killed first. It was determined that the two shots fired at Roscoe by Corporal Stephen
Vigour of the Auto Theft Unit were pivotal in the outcome because even though they weren't fatal,
shooting Roscoe in the arm and thigh incapacitated him and forced him to reevaluate the situation
leading to his suicide. Corporal Vigour was awarded a 2007 bravery medal for his action.
Of particular interest at the inquiry was the testimony of the two Mounties in charge of the
Marathorpe Detachment at the time of the mass murder. Sergeant Brian Pinder and Corporal James
Martin who was specifically in charge of the Roscoe incident when the bailiffs called the RCMP
for backup. Martin who by this time had been promoted to sergeant testified that they knew Roscoe
Roscoe was a risk and had a violent past and that's why they left two armed RCMP officers
there overnight instead of just one which would have been the norm for that situation.
And when asked why the RCMP didn't seem to be as aware of Roscoe's reputation as the locals in
Marathorpe were, Martin testified that while Roscoe had a reputation for being a cop hating
sociopath they hadn't actually had that many dealings with him hadn't really seen evidence of
his cop hating persona and it was their experience that when confronted by authority he would run
away. Martin was asked about finding the evidence in Roscoe's trailer that showed he'd been monitoring
RCMP officers and had a scanner tuned into the frequency. If they weren't aware of his cop
hating persona before that then surely this was clear evidence and it had been discovered about
12 hours before the massacre so the RCMP had time to take action. Martin was asked what action he
did take and he said he told the other members on the scene and asked them to be on the lookout for
guns but none were found until after the tragedy. Sergeant Martin said he'd gone over his decision
making many times in the six years since the tragedy but concluded that most of the decisions he
made that day were the right ones. He apologized however to the family of constable Peter Sheeman
who wasn't even on duty that day. Martin said that it was because of his personal oversight that
Peter was unarmed and wasn't wearing any protective gear but despite this he still maintained that
the RCMP made every preparation that they could. Without mentioning Sean and Dennis specifically
Martin then insisted that everything would have changed if anyone who knew what Roscoe intended
that night had simply called the RCMP to warn them. Quote, I would have pulled all my members
out of the area and called in the emergency response team. After the inquiry Justice
Parle released his final report stating that he found no failings in the training experience
or abilities of the officers who lost their lives. He was satisfied that the RCMP acted
appropriately in all circumstances as they knew them. He concluded that the incident was a uniquely
tragic event which could not reasonably have been foreseen or prevented. A number of recommendations
came out of the inquiry including the development of a threat assessment coordinator, the establishment
of national policy guidelines for securing potential crime scenes and the implementation of an active
shooter response program. It was also recommended that they review equipment, body armor and firearms
because the fallen four Mounties were determined to have been heavily outgunned by Roscoe.
The media reported the RCMP had committed to moving forward with the recommendations
and later that year the organization announced that it would spend at least $1 million to add
more high-powered guns to its arsenal. The families of the fallen four were generally
satisfied with the results of the inquiry but outside court Sean's father Barry Hennessey
said he was bitterly disappointed in the results. He said the inquiry was determined to reduce the
Marathorpe tragedy to black and white when really it existed in a world of gray. Barry didn't deny
that Sean and Dennis had culpability but stated that the RCMP have just as much culpability for
failing to secure the scene. Dennis Chiesman was released on parole in 2013 at age 29.
The parole board reported that he'd been a model offender during his prison sentence,
helpful with an excellent attitude who attended school and worked as a cleaner. Dennis,
still a man of few words, told the board that he hadn't lined up a job yet but he was working
on it and he planned to live with a relative until he could get his own place. Eighteen months after
that in 2015 Sean Hennessey was granted full parole at age 35. The board noted that he completed
his high school equivalency diploma while behind bars and had taken responsibility for his actions.
He told the board that he feels for the families of the four officers and he still thinks about his
role in the Marathorpe tragedy and had tried very hard to change who he was. He said he used to be
an immature self-centred person who did and sold drugs and hung around with unsavory characters
like Roscoe but he's a different person now. At each man's release the families of the fallen
four had mixed reactions but the common thread was hope that the man would turn their lives around.
And if the absence of any further news is an indication, they did. The only update on Sean
Hennessey and Dennis Cheeseman is that both men successfully completed their parole period
after release but the public remains divided. Some believe their sentences appropriately
reflected the gravity of the crime and their involvement but others believe Sean and Dennis
paid a price that was much too high, a price that not only covered their own crimes but also
those of James Roscoe, the one who was on site who pulled the trigger and who was no longer
around to face the music, take his own punishment and absorb his share of the public's devastation.
And many have pointed out that the RCMP also played a role by not adequately assessing the
threat posed by Roscoe and not taking the appropriate steps to keep their members safe.
But while Dennis Cheeseman and Sean Hennessey admitted fault, the RCMP did not and seemed
to escape the situation with a pat on the back and a few recommendations for change.
In a 2020 article in McLean's called The RCMP is Broken, author Stephen Mayer acknowledges that
the forces fraying under a rural policing model that's resulted in underworked, underpaid RCMP
officers who are not always as well equipped as their counterparts in cities or other police
forces. The article quotes criminologist Darrell Davies who was hired to help the Mounties spend
that $1 million to buy new rifles and upgrade their arms. As a result of his experience executing
this initiative, Davies ended up becoming a critic of the forces management culture,
which he described as excessively secret and authoritarian. He said the politics of the RCMP
and the secret subterranean nature of the organization is a major problem when it comes
to trying to decipher and understand what happened in situations like Mayer Thorpe.
The author argues that the problems with the RCMP are much more complicated than this,
stemming back to its ugly legacy of being created to control Canada's indigenous population.
And even with this legacy, the RCMP continues to make headlines with tragic and controversial
mistakes. Eleven years after the Mayer Thorpe massacre was another one in Moncton, New Brunswick
in 2014, when a man with a rifle was able to kill three Mounties because they were outgunned,
they'd only been equipped with pistols. And in April of 2020, there was the Porterpick
massacre in Nova Scotia, where an armed gunman went on a rampage over 13 hours, killing 22 people,
including one RCMP officer. Since that massacre, many questions have been asked of the RCMP's
response, like why the force failed to act on previous complaints about the gunman.
People also asked how he was allowed to move around for 13 hours while the RCMP looked for
him in the wrong places and failed to notify the public of the danger. These questions are only
the tip of the iceberg, but the force remains predictably tight-lipped. Tune in to the Nighttime
podcast's extended coverage and exclusive interviews on the Porterpick massacre for more information on this.
Every year, since the Mayer Thorpe tragedy, the four Constables who lost their lives that day have
been honoured in a number of ways, from anniversary ceremonies to candlelight vigils. Today, the Fallen
Four Memorial Park stands in Mayer Thorpe to commemorate Constables Anthony Gordon, Leo Johnston,
Peter Sheeman. The memorial depicts four large bronze statues, each a life-size likeness of the
four RCMP officers standing in what's described as the Four Positions of Readiness, all in the
centre of a quiet green space. Each officer had been assigned a position according to their
experience in the RCMP, which ranged from just a few weeks for Brock Myrol to five years for Peter
Sheeman. According to the website for the park Fallen4.ca, about 7,000 people visit each year
to remember them. The park is considered equally important both to the RCMP family and to the
town of Mayer Thorpe. On the 10-year anniversary of the Mayer Thorpe tragedy, which was in 2015,
Rod Nect, RCMP Senior Deputy Commissioner, aka one of Alberta's top Mounties at the headquarters
in Edmonton, spoke to Jana Prudin of the Edmonton Journal about the RCMP side of things.
He said the secret investigation meant that the RCMP couldn't talk publicly about what happened
at Mayer Thorpe, and that caused a growing public speculation that the officers had done something
wrong. He added that he was shocked by the criticism and speculation and the armchair
quarterbacking when the full facts of the case weren't publicly known. And he said,
by the time they were able to speak up at the inquiry, there was an established perception
that the RCMP was at fault, whether through incompetence, cover-up, poor training or lack of
equipment. Nect said it was part of the human condition to question why something happened
and find someone to blame for it. He was, of course, talking about the general public blaming
the RCMP. But he could just as well have been talking about the RCMP, blaming Sean Hennessy
and Dennis Cheeseman. The top Alberta Mountie added that he, too, had done a lot of soul searching
but also found nothing that could have been done any differently. Quote,
it wouldn't have mattered if they had the best body armour if they trained for six months before
that. They were ambushed pure and simple and they didn't stand a chance. At the end of the interview,
Rod Necht stressed that a situation can turn quickly. Quote, you can never prepare for that
random act. And Roscoe was that random act. At the end of the day, you have to blame the person
that pulled the trigger. That's the person that did it.
Thanks for listening and special thanks to We Talk of Dreams for audio editing and production
and Danielle Parody for research. We're doing something a little different to end today's
episode. After the first part of the series, a bunch of listeners have been sending me messages
directing me to what I now know is an iconic song released by Canadian songwriter Coe,
who's opened for Snoop Dogg and has a cult following thanks to his powerful lyrics and
live shows. Coe also told me he's a true crime buff and wrote this song called The Ballad of
Jimmy Roscoe in 2009. But I think it perfectly captures the angst that still surrounds this
tragedy 16 years later. This song comes from the perspective of James Roscoe, the man at the centre
of the whole tragedy, who was finally cornered into a hole where he had nothing to lose and
chose to take as many down with him as he could. The song is dedicated to those who lost their
lives that day, and it incorporates real police audio that's no longer publicly available.
Starting with the call made from the auto theft unit seconds after they first heard gunfire from
the concert hut. A huge thanks to Coe for permission to play this. You can find him at ko-nation.com,
and here's his song The Ballad of Jimmy Roscoe.
He's got a member down. Okay, you need to tell me what? I believe so. We just got here,
we just got here. Okay. Members went into the garage, and they were shot fired. Okay. Okay,
bounce up heading out that direction. He don't like himself and he don't know how to deal.
He spent most of his time with his cops in the field. He's unloading and cleaning the
steel thinking. They, they gon' feel how I feel if they come between me and my getting high.
Some they all gonna die. He's nervously dumping out a box of shells thinking. There's no way I'm
living in a cell and he's full. The officer's dead. Stingy gravel red where they dreaded. He's
nervously dumping out a box of shells thinking. There's no doubt I'm going to hell and he's full.
The officer's dead. Stingy gravel red where they bled. So no, no, so ho, forget.
I spent too much time on these seeds only to leave with a couple of keys and see I know that
I'm a problem but you the disease, you the disease. Then I'm fixing to get what I need. Not a man's
gon' take that from me. Then he's screaming, get off my property. He starts pumping shells
and dropping these over car payments and crops of trees. With that bad you think that you can't
bleed. Well I'm fixing to get what I need. Not a man's gon' take that from me. He's nervously
dumping out a box of shells thinking. There's no way I'm living in a cell and he's full. The
officer's dead. Stingy gravel red where they bled. He's nervously dumping out a box of shells
thinking. There's no doubt I'm going to hell and he's full. The officer's dead. Stingy gravel red
where they bled. So no, no, so ho, forget.
Shouldn't that, uh, when you heard the, uh, the gunshots and you heard some screaming,
do you remember any words, could you decipher any words or what was being said and amongst
that screaming? No, there were, there were no words. There was, there was just screams. Um,
and I don't remember how many. I recollect two or three screams but, but no words, no spoken words
at all. When the sheriff rolled up on the rice school residence, a little slow, a little hesitant.
See those cruisers, Park Soul still gave him a chair. They'd all been killed. It was father's
sons and constables dropped by a man, man who lost his soul and well, why'd you kill him, Jimmy?
You should have driven Jimmy and why'd you kill him, Jimmy? Well, he's nervously dumping out a
box of shells thinking. There's no way I'm living in a cell and he's full. The officer's dead. Stingy
gravel red where they bled and he's nervously dumping out a box of shells thinking. There's
no doubt I'm going to hell and he's full. The officer's dead. Stingy gravel red where they
bled so no, no so hope you forget. So no, no so hope you forget. So no, no so hope you forget.
It'll be all right a little now, get well.
