The trial for a man accused of killing two people and injuring a third in a 2011 hit-and-run crash in Coquitlam began Monday in a New Westminster court.

Cory Sater pleaded not guilty to all 10 charges against him, which include dangerous driving causing death, impaired driving causing death and failure to stay at the scene.

The incident happened in February 2011, when Charlene and Dan Reaveley stopped to help Lorraine Cruz, 26, and her boyfriend, Paulo Calimahin, after their vehicle hit the median on the Lougheed Highway.

As they stood at the side of the road, the driver of an SUV careened right into them and kept going.

Charlene Reaveley and Cruz were thrown 20 meters and died instantly, while Calimahin was seriously injured.

Crown counsel Christopher McPherson alleged it was an impaired Sater who was behind the wheel of the SUV that plowed into the group and drove away.

In court today, a 911 call made by Kimberley Moore, a friend of Reaveley’s, was played.

During the frantic call, a man in the background says “be careful”, following by the sounds of a collision. Moore starts screaming “oh my God” and minutes later, she tells the dispatcher that her friend is dead.

"It was very emotional,” said Lisa Reaveley, Charlene’s sister-in-law. “Just reliving the situation… and hearing the information kind of brings back raw emotion.”

McPherson said the Crown will take two weeks to present its case, providing testimony from witnesses at the scene and surveillance video from a Burnaby pub they claim shows Sater drinking the night of the crash.
