(Chain reaction collision)…It happened Saturday.

It involved four vehicles. The El Cajon Sector of the California Highway Patrol is investigating. They say the collision was reported at just after 11:00 Saturday morning on Westbound Interstate 8, west of Buckman Springs Road. The CHP says a preliminary investigation indicates a pick-up from Texas rear ended a Honda from El Centro, pushing the vehicle into a Subaru from Chandler, Arizona, which was pushed into the back of a Toyota from Yuma, Arizona. A female passenger in the El Centro vehicle was flown by Reach Air Ambulance to Sharp Hospital in San Diego. The male driver of the El Centro Honda was transported to Sharp via ambulance, as were other injuries. The Highway Patrol says the investigation is continuing and they are not prepared to release the names of those involved or the extent of the injuries. They have determined alcohol was not a factor in the collision.
