One person is dead and four more injured after a fatal head-on crash Monday.
On June 10, at approximately 3:45 p.m., Amador County California Highway Patrol Officers responded to a head-on traffic collision on Highway 49, south of Sandra Road. The investigation determined that Thomas Diermier, age 95, of San Andreas, was driving a 2014 Lexus RX350 northbound on Highway 49 at an undetermined rate of speed. Sean Vasco, age 38, of Plymouth, was driving a 2018 GMC Denali southbound on Highway 49 at 55-miles-per-hour. Diermier crossed over the solid yellow double lines into the southbound lane in order to pass a logging truck, which placed Diermier’s vehicle directly into the path of Vasko’s vehicle. The front of the Lexus collided with the front of the Denali causing disabling damage to both vehicles.
After the collision, Diermier’s vehicle became engulfed in flames. The initial responding CHP Officers and good samaritans at the scene attempted to extinguish the fire and extricated Diermier from his vehicle before it became fully engulfed. Despite life-saving efforts by first responders, Diermier succumbed to his injuries at the scene. Vasco and his passengers, three children, all 12-years-old of age, all sustained major injuries and were transported to various hospitals for treatment.
It is unknown if alcohol and/or drugs were a factor in this collision.
