Investigators say speed a factor in Byron Highway fatal rollover crash

A 27-year-old man died after a rollover crash off of Byron Highway in eastern Contra Costa County early Monday morning, according to the California Highway Patrol.

Officers responded at 2:04 a.m. to Byron Highway just north of Holey Road and found the man lying on the dirt shoulder outside of a 2019 Dodge Charger. He was taken by ambulance to a hospital in Antioch but died of his injuries there, CHP officials said.

Investigators determined that the man, whose name has not been released, was speeding south on Byron Highway and didn’t navigate a turn in the roadway, striking the dirt shoulder and rolling the vehicle over several times, according to the CHP.

He apparently was not wearing a seat belt and was ejected through the sunroof. Authorities have not determined if impairment was a factor, according to the CHP.

Anyone with information about the crash is asked to call the CHP’s Contra Costa-area office at (925) 646-4980.
