Calgary man found not criminally responsible in fatal stabbing of five

By Eric M. Johnson CALGARY, Alberta (Reuters) - The 24-year-old son of a policeman who fatally stabbed five people at a Calgary house party in 2014 was not criminally responsible, a judge ruled on Wednesday, saying a mental disorder blocked him from knowing his actions were wrong. Justice Eric Macklin, of the Court of Queen's Bench of Alberta, issued his verdict on Wednesday in the first-degree murder trial of Matthew de Grood, a case that has made national headlines, lawyers said.
