Crown seeks prior assault to increase sentence for ex-cop's violent arrest

Daniel Haworth suffered a skull fracture and traumatic brain injury from the body-slam while handcuffed; he died from a fentanyl overdose eight months later.
One incident could be an aberration. Two suggests something deeper.
The Crown argues that a 2013 altercation and the 2015 body-slam together reveal a pattern of violence by the former officer.

In a Calgary courtroom, a former police officer named Trevor Lindsay faces sentencing for a 2015 assault in which he body-slammed a handcuffed man, leaving him with a skull fracture and a brain injury from which he never fully recovered before his death. The proceeding asks a question older than any single case: whether a pattern of harm, once established, should weigh more heavily than any single act in isolation. What unfolds over six days may quietly redraw the boundaries of how institutions are held to account for the conduct of those who carry their authority.

  • A former Calgary officer convicted of aggravated assault now faces a sentencing hearing where prosecutors are pushing to have a prior violent incident treated as evidence of a deliberate pattern, not an isolated mistake.
  • Video footage from a 2013 helicopter unit captured Lindsay striking a handcuffed man multiple times — yet a testifying officer acknowledged under cross-examination that he saw nothing in the footage he would classify as excessive force.
  • The victim of that 2013 incident, Godfred Addai-Nyamekye, testified that after being handcuffed he was abandoned in East Village in minus 28 degree cold wearing only a tracksuit, forcing him to borrow a phone to call 911 for his own safety.
  • Daniel Haworth, the man body-slammed by Lindsay in 2015, suffered a skull fracture and traumatic brain injury and died of a fentanyl overdose less than eight months later — a human cost that shadows every argument made in the courtroom.
  • The defence is working to sever the two incidents and soften the characterization of the 2015 assault, while the Crown's strategy hinges on convincing the court that a pattern of conduct demands a heavier penalty.
  • The outcome of this six-day hearing is expected to set a precedent for how prior police conduct can be used as an aggravating factor in future accountability cases across Canada.

Trevor Lindsay, a former Calgary police officer, appeared in court Monday as his sentencing hearing began for the May 2015 body-slam of Daniel Haworth — a handcuffed theft suspect who suffered a skull fracture and traumatic brain injury. Prosecutors are seeking to have a separate 2013 altercation treated as an aggravating factor, arguing it reveals not a single lapse in judgment but a pattern of violence.

The 2013 incident was recorded by a HAWCS helicopter officer who responded to an officer-in-trouble call. The footage showed a man identified as Lindsay striking a handcuffed suspect, Godfred Addai-Nyamekye, with punches and knees. A testifying officer, Const. Jonathan Odland, described what he saw — but under cross-examination conceded he observed nothing he would classify as excessive force, and agreed the defence's characterization of Lindsay trying to lift a resisting man from the ground matched his reading of the video.

Addai-Nyamekye himself took the stand to describe the morning of his arrest. After helping a drunk friend get home, he lost control of a borrowed SUV in a snowbank. Officers handcuffed him — but rather than taking him to a station, they dropped him in East Village in minus 28 degree cold, wearing only a tracksuit. With a dead phone battery, he borrowed a stranger's phone to call 911, fearing he might not survive. His account of what happened next, when Lindsay arrived, was set to continue the following day.

Haworth, who was 35 at the time of the assault, died from a fentanyl overdose less than eight months after Lindsay body-slammed him. His death gives the proceedings a particular gravity. The six-day hearing will determine not only Lindsay's sentence but whether courts will allow prior violent conduct by officers to formally aggravate their penalties — a question with consequences that reach well beyond this case.

The sentencing hearing for Trevor Lindsay, a former Calgary police officer, began Monday with prosecutors arguing that a violent encounter from nearly two decades earlier should weigh heavily in determining his penalty. Lindsay stands convicted of aggravated assault for a May 2015 incident in which he body-slammed Daniel Haworth, a handcuffed theft suspect, causing a skull fracture and traumatic brain injury. The Crown wants the court to consider a December 2013 altercation between Lindsay and another man as evidence of a pattern—a prior act of violence that could push the sentence higher.

The 2013 incident was captured on video by a HAWCS helicopter tactical flight officer who responded to an officer-in-trouble call. In the footage, an officer identified as Lindsay can be seen struggling with a handcuffed suspect, Godfred Addai-Nyamekye, striking him multiple times with punches and knees. When the video was played in court, Const. Jonathan Odland testified about what he observed. Under cross-examination by the defence, however, Odland acknowledged he saw nothing in the footage that would constitute excessive force. He agreed that handcuffing suspects behind their backs is standard safety practice, though he noted that in this particular video, Addai-Nyamekye's hands appeared to be in front of him. The defence suggested Lindsay was simply trying to get the man up from the ground while he resisted—a characterization Odland said matched his perception of events.

Addai-Nyamekye took the stand late in the day to recount how he came to be arrested by Lindsay that morning. He had been called by a drunk friend asking for a ride home. After picking up the friend and two others, Addai-Nyamekye lost control of the borrowed BMW SUV and became stuck in a snowbank. A passing police van stopped, and he was handcuffed and taken into custody. But instead of being transported to a police station, the officers dropped him off in East Village wearing only a tracksuit, telling him to leave. With his phone battery dead and the temperature at minus 28 degrees Celsius, Addai-Nyamekye used a passenger's phone to call 911, fearing for his safety. He will continue his testimony on Tuesday, describing the encounter with Lindsay that followed his desperate call for help.

The case carries weight beyond the immediate facts. Haworth, 35 years old at the time of the assault, died less than eight months later from a fentanyl overdose. The six-day sentencing hearing will determine not only what penalty Lindsay receives but also whether prior incidents of violence by police officers can be used to establish a pattern of conduct that aggravates their sentences. The Crown's strategy—linking the 2013 altercation to the 2015 body-slam—suggests an effort to demonstrate that this was not an isolated lapse in judgment but part of a broader pattern of excessive force. The defence, meanwhile, is working to separate the incidents and to characterize the 2015 assault as something less than what the conviction suggests. What emerges from the courtroom over the coming days will shape how police accountability cases are argued in the future.

Why does the Crown think the 2013 incident matters so much for sentencing in 2015?

Model

They're arguing it shows a pattern. One incident could be an aberration—a bad day, a mistake. Two incidents separated by 17 months suggests something deeper in how he uses force.

Inventor

But the video from 2013 is ambiguous, isn't it? The officer testified he didn't see excessive force.

Model

Exactly. That's the tension. The Crown sees two violent encounters with handcuffed or restrained people. The defence sees context—resistance, safety concerns, judgment calls. The judge has to decide which narrative holds.

Inventor

What strikes you about Addai-Nyamekye's story—being dropped in East Village in the cold?

Model

It's a separate injustice that frames everything. He's abandoned, desperate, calls 911 for help, and then encounters Lindsay. The court will hear all of that as context for what happened next.

Inventor

And Haworth died eight months later. Does that change the sentencing calculation?

Model

It complicates it. The injuries Lindsay inflicted—the skull fracture, the brain trauma—didn't directly kill him. But they happened to a man whose life was already fragile. The Crown will argue that matters.

Inventor

What's really at stake in this hearing?

Model

Whether prior conduct by a police officer can establish a pattern that increases punishment. If it does, it changes how these cases are prosecuted. If it doesn't, each incident stands alone.
