RCMP funeral honours B.C. officer killed in Surrey crash

The twin brother of a B.C. RCMP officer killed in a crash told a regimental funeral he can only hope to be the officer and the man that his brother became.

Ben Oliver's voice was filled with emotion as he said he and his brother were most of the way toward their childhood dream of becoming Mounties together and living in houses across the street from each other.

Mourners heard that, as children, the inseparable brothers dressed as Batman and Superman, foreshadowing the careers in policing they both later pursued.

Const. Adrian Oliver, an officer with the Surrey detachment, was killed last week when his unmarked cruiser was struck by a transport truck.

RCMP Commissioner Bob Paulson told the funeral Oliver embodied the values the RCMP holds dear, saying the constable was a compassionate man who became a caring police officer.

A sea of red-coated RCMP members filled the suburban Langley auditorium and politicians attended from all three levels of government.

The Mounties earlier marched through Langley, B.C., Tuesday afternoon as part of the funeral procession.

B.C. Justice Minister Shirley Bond attended the funeral, along with police and border security officers from across Canada, the U.S. and Australia.

The list of speakers for the service included:

- Chief Supt. Andrew Boland, a close family friend.

- Brad Brothers, a close friend of Const. Oliver.

- Const. Shelagh Mitchell, Const. Oliver’s spouse.

- Const. Benjamin Oliver, Const. Oliver’s brother.

- Commissioner Bob Paulson, head of the RCMP.

Oliver joined the force in 2008 and arrived at the Surrey detachment in 2009. He was the second generation of his family to serve with the RCMP.

The cause of the collision that killed the officer remains unclear and Vancouver police have taken over the investigation.
