Mitchell was shot dead by Ridge Meadows RCMP after officers tracked down his van on a rural road last May.
The 26-year-old was the suspect of a double murder in a Burnaby sushi restaurant just days before.
Police also believe Mitchell tried to kill his landlord two nights after the incident and that he had a hitlist — complete with names, addresses and phone numbers — of people he intended to harm.
Mitchell shot at officers and was fatally wounded when they returned fire, police said.
The VPD agreed to a request by the RCMP to investigate the shooting.
"Our investigations show that there's no evidence to support there was any wrongdoing on the part of the officers involved," said Const. Brian Montague, spokesman for the Vancouver Police Department.
Montague said no charges will be forwarded to Crown counsel, but a coroner’s inquest will begin on Nov. 5.Suggest a correction
