An Atwater man died in a head-on collision Tuesday morning on North Vincent Road, the California Highway Patrol reported.

The deceased was identified as Mark Keach, 56, of Atwater.

The two-vehicle collision caused major injuries to four other people, the CHP reported.

Around 8:30 a.m. Tuesday, Keach was driving a Chevrolet Cruze north on North Vincent Road with his sons — Logan Keach, 21, and a 17-year-old boy — as his passengers.

An Infiniti SUV, driven by Mercedes Adams, 44, of Fort Wayne, Indiana, was traveling southbound on Vincent, approaching West Harding Road. Jasmine Dontz, 20, of Fort Wayne was a passenger in the SUV.

The Infiniti began to drift off the shoulder of the road and Adams attempted to steer it back, but over-corrected, which sent the SUV into the northbound lane and directly into the path of the Chevrolet.

The two vehicles collided head-on and ignited a fire in the Chevrolet, according to the CHP.

Mark Keach was pronounced deceased at the scene.

Both brothers, along with Adams and Dontz, sustained major injuries in the collision and were taken by air ambulance to area hospitals.

The CHP does not suspect drugs or alcohol were factors in the crash. The investigation is ongoing.
