A lawyer for a mentally ill man who fatally stabbed five young people at a Calgary house party is appealing a determination that he remains “a significant risk to public safety” and wants him released from custody.
Matthew de Grood, 31, was found not criminally responsible for the 2014 killings of Zackariah Rathwell, Jordan Segura, Kaitlin Perras, Josh Hunter and Lawrence Hong because he was suffering from schizophrenia at the time.
