The man accused of Calgary’s worst ever mass murder has been deemed not criminally responsible.
24 year-old Mathew de Grood pleaded not guilty through his lawyer Allan Fay to the stabbing death of five people at a Calgary house party in 2014.
In a agreed statement of facts de Grood admitted to the time at which he stabbed the victims, and to the knife he used.
However lawyers for both the Crown and defence were in agreement Tuesday that de Grood was was experiencing a break with reality and unable to distinguish between right and wrong when the killings took place.
The court heard his parents and siblings had noticed questionable activity leading up to the night of the stabbing.
The 24 year old was said to have been withdrawn in the month leading up to the attack and that he had posted on social media bout Darth Vader, the end of the world, religion and vampires.
In his verdict Justice Eric Macklin agreed with the expert witnesses that de Grood did not that what he was doing was morally wrong.
Lawrence Hong, Joshua Hunter, Kaitlin Perras, Zackariah Rathwell and Jordan Segura were killed in the attack at a party celebrating the end of class at the University of Calgary.
