11 people who have been found not criminally responsible by a court

Blair Donnelly, 64, faces three counts of aggravated assault over allegations he stabbed and injured three people at a Vancouver Chinatown festival on Sunday.

Here’s a look at some other cases in which the finding was made or sought:

Matthew de Grood: Stabbed five young people to death in a Calgary house party in 2014. A judge found him not criminally responsible for the murders because he was suffering from schizophrenia.

Gregory Despres: Fatally stabbed two elderly neighbours in Minto, N.B., in 2005, decapitating one of them. Despres, a naturalized U.S. citizen, had crossed the border despite guards finding him with a small arsenal including a chainsaw, a sword and brass knuckles. He told them he was an assassin on a military mission. Three psychiatrists diagnosed him with paranoid schizophrenia. He was found not criminally responsible.
