The Night the Party Turned Silent: Matthew Degrood and the Brentwood Stabbings

April 15, 2014. What began as a small student gathering near the University of Calgary ended in one of the most devastating nights in the city’s history. Five young people went to a house party in Brentwood and never made it home. The accused, 22-year-old Matthew DeGrood, the son of a Calgary police officer, would later be diagnosed with schizophrenia and found Not Criminally Responsible for the killings. In this episode, we explore:• What witnesses described from inside the house• The disturbing behaviour leading up to the attack• The legal meaning of Not Criminally Responsible in Canada• The ongoing review board process• And the difficult tension between treatment and public safety This is not a story about revenge or a clear motive. It’s a case about psychosis, missed warning signs, and the ripple effects that continue more than a decade later. Five families are still living with the aftermath.
