ALBUQUERQUE, N.M. (AP) - Authorities say a driver had no alcohol or drugs in his system when he slammed into a pick-up truck, triggering a series of collisions on a New Mexico highway that resulted in the deaths of three passengers of a commercial bus.
The Sandoval County sheriff released the results of a toxicology report Thursday following the July bus crash on a stretch of Interstate-25 north of Albuquerque.
Authorities say the bus driver lost control while trying to avoid the crash into the pick-up truck. The overturned bus was then sideswiped by a semi-truck.
Sheriff's officials say excessive speed was not a factor.
The investigation's final results are to be provided to prosecutors in about two weeks.
The bus was travelling from Denver to El Paso, Texas. Two dozen people were injured.
