The BC Coroner has determined the accident itself killed a grandmother last summer before her vehicle burst into flames.
The coroner has now determined that 49-year-old Peggy (Margaret) Irene Ann Armstrong died before the fire and therefore the rescuers could not have changed the outcome if they had been able to pull her from the car.
Coroner Andrew Cave found that Armstrong died of multiple traumatic injuries sustained in the car crash.
Rescuers were able to pull Armstrong's 2-year-old grandson to safety before the van ignited, leaving him with only minor injuries.
Ms. Armstrong was the driver of a minivan that was in a head-on collision with a semi-trailer on Highway 97A south of Enderby at about 4 p.m. on July 17.
According to RCMP Spokesman Gord Molendyk witnesses told RCMP they observed the minivan weaving on the road and crossing the center line.
The coroner was unable to determine any cause for this driving behaviour as road conditions were all favourable at the time. The van was too far destroyed by the fire and could not be examined.
The Coroner ruled the death accidental and made no recommendations.
