Footage shows van zooming through red light before fatal crash

New developments in deadly Surrey crash The investigation into an alleged drunk driving crash that left a grandmother dead is turning up some alarming details.

Surveillance video has surfaced of the moments leading up to a grisly crash that killed a 62-year-old woman in Surrey this week.

The video appears to show a green GMC Safari van zooming through a red light at the intersection of 152nd Street and 72nd Avenue around 6:30 p.m. Wednesday, narrowly missing a number of other vehicles.

Off camera, the van T-boned a red sedan being driven by Port Coquitlam resident Janet Dudgeon, who died at the scene.

Dudgeon's 84-year-old mother, Barb, was with her in the passenger seat. Though she survived, she suffered a cracked pelvis, broken ribs and head injuries, according to her family.

Mounties said a suspect driver has been arrested, and that alcohol is believed to be a factor in the collision.

The 68-year-old suspect’s name won't be released unless charges are approved, which Cpl. Scotty Schumann said could take a while.

"These investigations are very complex with a lot of technical data that will have to be compiled over the next couple months," Schumann told CTV News.

The driver of the van was injured as well, though the extent hasn't been confirmed. Police said the individual was taken to hospital and then placed in their custody. As of Friday afternoon, he had been released from hospital and was at home because he had not yet been charged.

A 75-year-old passenger in the van was not seriously hurt.

Investigators have determined that prior to the deadly collision, the van struck four other vehicles, including a TransLink bus. The van also hit a telephone pole, and crossed the median at one point before the fatal crash, police said.

The crime scene is so sprawling that Surrey RCMP have called in resources from their property crime unit. They’re going door-to-door along 72nd Avenue looking for additional surveillance video.

Anyone who might have seen a green GMC Safari in the area Wednesday afternoon is asked to contact the Surrey RCMP detachment or Crime Stoppers.
