The five victims of a fatal car crash in Surrey, B.C., over the weekend represented three generations of the same family.

The victims have been identified by family members as two children, ages 3 and 5, their mother, their aunt and their grandmother. The family members asked CTV News for privacy.

The victims were travelling in a dark sedan on the Pacific Highway around 11 a.m. PT Sunday, just north of the U.S. border, when they were struck by a white van.

RCMP Sgt. Dale Carr said Sunday it appeared the white van sped through a red light at the intersection and collided with the car, which was so badly hit that it was split in half.

Carr said the crash was one of the most horrific scenes he’s seen in his 26 years with the RCMP.

The driver of the white van, a 46-year-old man from Langely, B.C., was airlifted to hospital, where remains in hospital in serious, but stable condition. He is being considered a suspect in the crash.

Meanwhile members of the RCMP’s Traffic Services Criminal Collision Investigation team and the Lower Mainland Integrated Collision Analyst/Reconstruction Services continue to investigate the cause of the crash.

“While we recognize the complexity of this investigation, we will use all available resources and information to ensure all contributing factors are looked at and a cause is identified,” Surrey RCMP Insp. Lee Chanin said in a statement issued to media.

“While we continue to investigate this horrific incident, our thoughts and prayers go out to the families affected by this tragic collision.”

No charges have been laid.
