High speeds and slick roads are to blame for a fatal car accident in Canyon County overnight.

Idaho State Police say 18-year old Eric Gonzales of Caldwell was driving very fast west bound on Ustick Road when he went through the stop sign at Pride lane.

Troopers say the 1987 Mazda slid through a yard and went airborne, rolling multiple times, finally coming to rest on its wheels.

Gonzales was not wearing his seat belt.  He was ejected from the car, and died at the scene.

His passenger, 24-year old Adrian Albor-Cardenas of Homedale was wearing his seat belt.  He was taken to Saint Alphonsus Regional Medical Center with injuries to his shoulder. 

"The witness said that they passed him, went through the stop sign, did not stop at the stop sign where he lost control of the vehicle in the intersection," Idaho State trooper Scott Tulleners said.

This crash is still under investigation, but ISP believes alcohol was also a factor in the crash.
