The Canada College Party Massacre: The Calgary Stabbings

Quick Read

A seemingly normal college party in Calgary celebrating the end of classes turned into Canada's worst mass murder when a law student, Matthew Degrood, stabbed five friends, later claiming he was fighting a war against vampires and werewolves.
Matthew Degrood, a promising law student, stabbed five friends at a Calgary college party, claiming they were 'werewolves' in a 'war'.
He was found 'not criminally responsible' due to a psychotic episode caused by schizophrenia, sparking widespread controversy.
Victims' families endure annual reviews, opposing Degrood's increasing privileges and advocating for systemic changes to the 'not criminally responsible' designation.

Summary

On April 15, 2014, five young people—Joshua Hunter, Zachariah Rothwell, Jordan Sigura, Lawrence Hong, and Caitlyn Perez—were fatally stabbed at a University of Calgary 'Bermuda shorts day' party. The perpetrator, 22-year-old Matthew Degrood, a psychology graduate accepted into law school and son of a high-ranking police officer, was apprehended quickly after being chased by his best friend, Brendan. Degrood exhibited extreme delusions, believing he was the son of God, the Egyptian god Anubis, and Darth Vader, fighting a war against the Illuminati, vampires, and werewolves on a full moon night. He claimed his victims were werewolves and that he needed to dismember their bodies. Despite his full confession, he was found not criminally responsible due to schizophrenia causing a psychotic episode. This verdict has led to ongoing controversy, with victims' families annually challenging his increasing privileges and potential reintegration into society, citing his past 'decompensation' (worsening mental illness symptoms) even while under supervision.
This case highlights the complex and often contentious intersection of severe mental illness and the justice system, particularly when it results in mass murder. The 'not criminally responsible' verdict, while legally sound based on psychiatric evaluations, creates profound and lasting trauma for victims' families, who are forced to confront the perpetrator's potential release and struggle with a system that prioritizes treatment over traditional punishment. It also raises public debate about the criteria for criminal responsibility and the balance between public safety and mental health rehabilitation.

2Perpetrator's Background and Delusional State

Matthew Degrood, a 22-year-old psychology graduate with a minor in law and society, was the sole suspect. He was accepted into law school and came from a respected family, his father being a high-ranking police officer. During his arrest and subsequent psychiatric evaluations, Degrood exhibited severe delusions, believing he was the son of God, the ancient Egyptian god Anubis, and Darth Vader, fighting a war against the Illuminati, vampires, and werewolves. He carried garlic to repel 'zombies' and claimed his victims were 'werewolves' he needed to kill quickly and dismember.

3The 'Five' Text Message and Premeditation Debate

Hours before the murders, Matthew texted a co-worker, 'Trust that I never hurt anyone. All will be known. Five.' This message, sent just before he killed five people, became a central point in the debate over whether the murders were premeditated, despite his later 'not criminally responsible' verdict.

The co-worker's testimony and Matthew's text message are discussed at .

4Not Criminally Responsible Verdict and Public Outcry

In May 2016, Matthew Degrood was found not criminally responsible (NCR) for the murders due to schizophrenia causing a psychotic episode. This verdict, based on expert psychiatric testimony, meant he was sent to a psychiatric facility for treatment rather than prison. The decision sparked significant public backlash and heartbreak among the victims' families, who felt it did not deliver justice.

5Ongoing Struggle for Victims' Families and Degrood's Privileges

Victims' families are mandated to attend annual review board hearings, where they receive updates on Matthew's treatment and progress. They have consistently opposed his increasing privileges, such as unsupervised day visits and moves to group homes, arguing that his past 'decompensation' (worsening mental illness symptoms) in 2019 and 2021 indicates he remains a risk and should not be granted further freedoms. His parents continue to advocate for his full reintegration, including moving back home, but these requests have been denied.

Lessons

  • Recognize the critical importance of early intervention and support for individuals experiencing mental health crises, as untreated severe mental illness can have devastating consequences.
  • Advocate for clear and transparent legal frameworks regarding 'not criminally responsible' verdicts, ensuring that victim families' perspectives are genuinely considered alongside rehabilitation efforts.
  • Understand the complexities of mental illness in the justice system, acknowledging that a legal finding of 'not criminally responsible' does not diminish the horrific impact on victims and their loved ones.

Narrator

"It's a very interesting case because it's actually widely, well, I don't want to say widely because it's actually being underreported in my opinion or has been underreported, but it has been compared to the Idaho 4 massacre, but the Canadian version.
