A son of a well-respected Calgary Police Service officer has been charged with first degree murder for the mass stabbings of five people at a house party in Brentwood, Calgary.
Matthew Douglas de Grood, who recently graduated from the University of Calgary with a degree in psychology and law and society, is the son of Inspector Doug de Grood who has been with the Calgary Police Service for 33 years.
"This is the worst mass murder in Calgary's history," Rick Hanson, Calgary police chief, said at a news conference.
"We have never seen five people killed by an individual at one scene. The scene was horrific."
The young de Grood executed the stabbing spree shortly after arriving at the party. Using a large knife, he stabbed the victims one by one shortly aabout 1 a.m. Tuesday.
The identities of the five victims, four men and a woman, will be released once the autopsies are finished. They are aged between 22 and 27 and were all "good kids."
Hanson said none of the victims nor the young de Grood had any prior involvement with the police.
The motive behind the Calgary attack remains unknown. The elder de Grood and his wife, described as both "incredibly cooperative in the investigation," were utterly shattered over the incident.
"He is absolutely devastated, he's heartbroken, as his wife is," Hanson said. "They feel so much pain."
