Police have linked the gun used in the slaying to two people in a Burnaby, B.C., restaurant and the shooting of a man two days later, to the weapon seized from slain suspect Angus David Mitchell.
Mitchell, who was killed in a confrontation with police Wednesday in Maple Ridge, had been described by police as a suspect in the non-fatal shooting of a 51-year-old man in Burnaby Tuesday and the double homicide May 27 in which the owner of the sushi restaurant and a woman employee were shot to death.
The wounded man was a former landlord of Mitchell's, but police have not made public any connection between Mitchell and the victims of the restaurant slayings.
They were Huong (Andy) Tran, 36, and his employee, Chinh (Vivian) Diem Huynh, 34, a single mother of a young daughter.
"Forensic examination has now confirmed that the weapon seized from Mitchell was indeed the weapon used in the double homicide and also the one used in the attempted homicide of the Burnaby shooting victim," Sgt, Jennifer Pound, of the Integrated Homicide Investigation Team, said Friday.
In a related development Friday, Victoria police revealed that its officers had seized a weapon from Mitchell under the Mental Health Act in February, but had returned it to him several weeks later.
It's not known if it was the same weapon, a rifle, that was used in the Burnaby shootings.
Victoria police have asked the Vancouver force to act as an independent force to investigate the seizure and return of the weapon.
