Brentwood Massacre Trial: Matthew de Grood found not criminally responsible

Matthew de Grood was suffering a mental disorder and didn’t appreciate what he was doing was wrong when he murdered five young Calgarians, a judge ruled Wednesday.

In determining de Grood, 24, was not criminally responsible, Justice Eric Macklin accepted the opinions of three experts the admitted killer was experiencing a psychotic episode at the time of the slayings.

“I find on a balance of probabilities that at the time he caused their deaths, Matthew de Grood was suffering from a mental disorder that rendered him incapable of appreciating or knowing that his actions were wrong,” Macklin said.
