RCMP officers in Saanich, B.C., have identified 22-year-old twin brothers Matthew and Isaac Auchterlonie as the two armed bank robbers who were killed by police in a shootout on Tuesday.
Six police officers were injured in the shootout late Tuesday morning at the Bank of Montreal in Saanich on southern Vancouver Island.
Police also said they had to dispose of explosive devices that were in a vehicle associated with the suspects on Thursday.
The Auchterlonie brothers, both 22, were from Duncan, about 60 km northwest of Victoria. According to RCMP, neither of the brothers had criminal records; they were not previously known to police.
"There are still many questions and investigation efforts that need to take place in order to fully understand what took place and why," said Cpl. Alex Bérubé at a Saturday news conference.
"The motive behind the armed robbery and subsequent exchange of gunfire with police has not yet been determined."
The Vancouver Island Integrated Major Crime Unit (VIIMCU) is leading the investigation. The Independent Investigations Office, the oversight body which reviews all police actions that result in death or serious harm, is also investigating.
Bérubé said police had spoken to the family of the suspects, who were cooperating with the investigation. The B.C. Coroners Service identified the brothers on Friday, according to Bérubé.
Police said they are still looking for public tips regarding the suspects' car, a white 1992 Toyota Camry with two black racing stripes over the hood and roof.
They are asking anyone with any information regarding either the brothers or their car to contact VIIMCU at 250-380-6211.
