A serious crash left two people in critical condition Saturday night.

The Vernon North Okanagan RCMP is investigating the Nov. 10 multi-vehicle crash in the East Hill area around 11 p.m.

Officers responded to the 2700-block of 15th St where they found BC Emergency Health Services and Vernon Fire Rescue Service personnel assisting the two occupants of a Pontiac Grand Am.

Officers also found two other vehicles and a hydro pole at the scene that had been damaged. 

The investigation determined the Grand Am was travelling at a high rate of speed when it lost control and left the roadway, colliding with the two unoccupied vehicles and the hydro pole.

"Both the driver and passenger of the Pontiac were extricated and transported to hospital for treatment of serious, life-threatening injuries," said Const. Chris Terleski, media relations officer.

A member of the RCMP Integrated Collision Analysis and Reconstruction Service attended the scene and is assisting with the investigation.

"Speed is believed to be a factor in the crash and police are continuing to investigate," said Terleski.
