A collision between two vehicles at a rural intersection outside of Keyes killed a Ceres man and seriously injured a Turlock resident.
The deceased was identified by the Stanislaus County Coroner's Office as Tony Perez, 79, of Ceres.
The California Highway Patrol said the collision was caused by one of the vehicles running a blinking red light at the intersection, but at this point it's unclear which party failed to stop.
The collision happened just before noon Saturday at the intersection of Faith Home and Keyes roads.
A 2009 Mercedes-Benz, driven by Bob Manuel Andrade, 45, of Turlock was headed westbound on Keyes Road, approaching the intersection with Faith Home Road at an unknown speed.
Perez was driving a 2013 Hyundai sedan southbound on Faith Home, approaching the same intersection.
"It is unclear at this point, which vehicle failed to stop at the red light which caused them to collide in the intersection," the CHP said in a news release.
The impact caused major left side damage to the Hyundai. It was found on its left side, leaning against an almond tree on the north shoulder of Keyes Road, just west of Faith Home Road, facing in an easterly direction, according to the CHP.
The Mercedes-Benz had sustained major front-end damage and was found on its wheels, on the north shoulder of Keyes Road, just west of Faith Home Road, facing in a westerly direction.
Emergency personnel arrived at the scene and pronounced Perez deceased.
Andrade sustained major injuries from the crash and was taken by ambulance to a nearby hospital.
Both men were wearing seat belts at the time of the collision.
The CHP does not suspect drugs or alcohol were factors in the collision. The investigation remains ongoing.
