Use-of-force expert to testify at inquest for DTES man shot by police

A use-of-force expert will testify Tuesday at the coroner's inquest into the death of a man who was shot by police in 2011 while waving a machete at officers in the Downtown Eastside.

Police said that Darrell Elroy Barnes was swinging the machete over his head as he advanced on police officers in the 300-block of Powell Street last July, when he was shot and killed.

Gregg Gillis, a police use of force expert, is set to give evidence before the coroner's jury in Burnaby. A toxicology expert is also scheduled to testify before the inquest.

On Monday, VPD Const. Kirk Longstaffe told the coroner's jury in Burnaby that he first fired several shots from a bean bag shotgun, and that it had no effect on Barnes.

Longstaffe said he then brought out his pistol and fired two or three shots. His partner also fired her weapon.

Paramedics testified Barnes was unresponsive when they arrived at the scene.

Co-worker describes addiction

John McCann, a former co-worker, told the jury Monday that Barnes worked as a waiter at a hotel pub and was addicted to crack cocaine.

McCann said Barnes had found a machete in the pub's washroom about a month earlier and was told to throw it away.

The court heard that Barnes had worked a shift the day he died and seemed depressed.

McCann said Barnes, who was 48 years old, had often told him that he didn't think he would live past 50.
