RCMP caught up with 26-year-old Angus David Mitchell in Maple Ridge on Wednesday, about three hours after issuing a public warning about him.
Supt. Dave Walsh said Mitchell was shot in a confrontation with emergency response team officers in a rural area.
Police were called after reports that someone had seen a van believed to be owned by Mitchell.
RCMP said he was a suspect in the deaths of a man and woman who'd been gunned down in a restaurant on Sunday and in the shooting and wounding of his former landlord on Tuesday.
Police said Mitchell had been evicted from his home six months ago, around the time he came to legally posses a hunting rifle.
Sgt. Jennifer Pound of the Integrated Homicide Investigation Team couldn't say if there was a relationship between Mitchell and the deaths of two people in the restaurant.
"As far as a motive goes in that homicide, we still don't have that," she said. "We need to have forensic evidence, really, to identify anybody as a suspect and in a two-day turnaround we don't have that evidence yet."
Pound said there are several factors that appear to link the two crimes, including a similar weapon, but forensics experts need to confirm that.
Insp. Tim Shields said Mitchell wasn't known to police, although officers had once been called to a complaint involving him.
"He has come up on police radar in the past, but that said, he is not known to police, he has not been charged with any criminal offence in the past."
Mitchell also had some conflict with former employers and co-workers, and Shields said police warned them Wednesday morning to be on the lookout for the armed and unstable man.
He said Mounties warned people who had previous contact with Mitchell "to make themselves difficult to locate."
Vancouver police said the RCMP has called on the force to investigate the fatal shooting. (The Canadian Press, News1130,CKNW)
