‘I’m truly sorry:’ Calgary mass killer says he suffers from survivor’s guilt
CALGARY — A Calgary man found not criminally responsible for the stabbing deaths of five young people four years ago told a review board he is sorry for what he’s done and will do everything he can to make amends.
Matthew de Grood told the Alberta Review Board he wishes the “terrible tragedy” had never happened.
“It grieves me knowing the pain, fear and agony I’ve caused. I’ve done a terrible wrong,” de Grood told a hearing Friday. “I desperately wish it had never happened. I take relapse prevention seriously. I will do everything in my power to make amends.”
The review board’s annual hearing is to get an update on de Grood’s progress and determine if he should be granted more freedom at the Calgary hospital where he is housed.
