A man who stabbed five young people to death at a Calgary house party will not be released from a group home after a ruling Thursday from Alberta’s highest court.
Matthew de Grood, who is now in his early 30s, was found not criminally responsible in 2016 for the killings of Zackariah Rathwell, Jordan Segura, Kaitlin Perras, Josh Hunter and Lawrence Hong. He was suffering from undiagnosed and untreated schizophrenia at the time of the stabbings in 2014.
