A fatal collision Tuesday afternoon in a rural part of Turlock was caused by one driver running a stop sign at a high rate of speed, the California Highway Patrol reported.

The collision claimed the life of Juan Carlos Mata, 42, of Turlock and critically injured Jacklyn Frost, 58, of Hughson.

The collision happened around 4:15 p.m. Tuesday at the intersection of Walnut Avenue and Bradbury Road. The intersection forms a T with Walnut ending at Bradbury and an orchard on the other side.

Mata was driving a 2017 Toyota Corolla southbound on Walnut approaching the intersection with Bradbury at a high rate of speed. According to the CHP, Mata ran the stop sign and the painted white limit line and proceeded into the intersection, just as Frost’s vehicle was entering into the intersection.

Frost was driving a 2000 Toyota Tacoma westbound on Bradbury and was traveling at approximately 55 miles per hour, the CHP reported. Bradbury does not have a stop sign at the intersection.

The front of Frost’s Tacoma broadsided the driver’s side of Mata’s Corolla. The force of the impact sent both vehicles spinning out of control until colliding with a wooden post and metal cable fence. The Tacoma continued southbound along the shoulder before coming to a stop.

Mata’s vehicle spun into an orchard and struck a walnut tree front on. Mata had sustained fatal injuries in the crash and was pronounced deceased at the scene.

Frost was pinned inside the truck. The Turlock Rural Fire Department was dispatched to the scene and was extracted by the firefighters and taken by air ambulance to Memorial Medical Center in Modesto with major injuries.

Both the Mountain View Fire Department and the Turlock Fire Department provided mutual aid during the incident.

It’s unknown at this time if alcohol or drugs were factors in the collision. The investigation remains ongoing.
