The murder suspect shot and killed by RCMP officers in B.C. Wednesday grew up in a wealthy family in the Okanagan region, but his life started to go off the rails in his teens, CBC News has learned.

Angus David Mitchell died in a hail of police bullets in the Fraser Valley east of Vancouver after he became the subject of a manhunt as only the suspect in an attempted murder on Tuesday and a double homicide on Sunday at a sushi restaurant in Burnaby. 

"He never smiled, he always had the mean look on his face," said Peter Ortman, who played soccer in Vernon with Mitchell throughout high school

"He stopped playing sports and he ... hung out with the drug people," Ortman said. "Maybe that's how it happened, how his life evolved, I guess."

RCMP spokesman Gord Molendyk said Mitchell’s name came up a number of times in connection with investigations, but was never recommended for any criminal charges by officers at the Vernon detachment.

Mitchell's family lived in a $3-million house on the shores of Okanagan Lake. His grandfather owned one of the most successful Caterpillar equipment dealerships in Canada, until it was sold in 1989.

However, at least one other family member also ran into trouble with the law. Police said his brother, Peter Mitchell, was believed to be involved in Vernon’s drug trade.

Peter Mitchell was sought on a province-wide warrant for drug trafficking and failing to attend court, according to a Crime Stoppers report in 2008.

Ortman said it was a strange experience to hear of Angus Mitchell’s death at the hands of police on Wednesday.

"Yeah, that just blew my mind. It's bizarre when you hear of people you know getting into stuff like that."
