Three weeks after the crash that killed his mother on Highway 132, a 5-year-old boy died from injuries sustained when he was thrown from the vehicle.
Michael Boesen died at UC Davis Medical Center on Monday.
Autopsy results have determined his mother, who was driving the evening of the crash on Oct. 17, was under the influence of alcohol, according to California Highway Patrol Officer Faustino Pulido. He would not say what her blood alcohol content was but said it was above the legal limit.
The mother, Sarah Nicole Cahoon, along with Michael and her daughter, 9-year-old Jasmin Povio, all of Coulterville, were eastbound on Highway 132 west of Piney Creek Road in a minivan when it drifted onto the right shoulder and up an embankment on the south side of the highway.
The minivan overturned multiple times back onto the road, the CHP said. Cahoon was ejected, and the van rolled over her before coming to rest. She was not wearing a seat belt, and neither was 5-year-old Michael, who was thrown clear of the wreckage.
Jasmin, who was wearing a seat belt, suffered minor injuries.
