The victims of a horrifying B.C. car crash have been identified as three generations of the same Surrey family.

The accident claimed the lives of three adults and two small children, and was described by first responders as one of the most terrible accidents they’ve ever encountered.

Family members, who asked CTV News for privacy, told CTV News the victims are a mother, her two children – a three-year-old girl and her five-year-old brother – their aunt and a grandmother.

All five were pronounced dead at the scene.

All of the deceased were in a 1994 Toyota Corolla on the Pacific Highway just north of the U.S. border around 11 a.m. Sunday when it was struck by a 2012 Dodge Caravan suspected of speeding through a red light at the intersection of 32nd Avenue.

The smaller car was sent flying into a metal pole, shearing the vehicle in half. Debris flew hundreds of metres, and the impact was so severe a pair of sunglasses were imbedded into the metal.

“I can tell you from my experience of 26 years in the RCMP attending multiple motor vehicle crashes, multiple homicides, [it’s] one of the most horrific scenes I’ve ever seen,” Surrey RCMP Sgt. Dale Carr said.

The surviving minivan driver, a 46-year-old Langley man, is being treated as a suspect in the crash. He was air lifted to hospital, where he remains listed in serious but stable condition in hospital.
