A 40-year-old man died Tuesday morning as a result of all-terrain vehicle accident at a ranch southeast of Los Banos, said California Highway Patrol officer Matt Pinheiro.
The man from Dos Palos, who was not identified Tuesday because his family had not been notified of his death, was an employee of the ranch.
He started work at 8:30 a.m. and headed out on the ATV, driving through the large private ranch off Canyon Road near Interstate 5.
At some point, the ATV hit a hole in the ground, causing the man to be ejected and suffer fatal head injuries, Pinheiro said.
The man was dead when he was found by a fellow employee about 11:30 a.m., so investigators don't know what time the accident occurred or when the man succumbed to his injuries.
He was not wearing a helmet, Pinheiro said.
