SAN DIEGO — A man was killed in a rollover crash near Palomar Mountain on Monday, said the California Highway Patrol.

Around 5:45 p.m., authorities say a 24-year-old Valley Center resident was driving a Mazda MPV westbound on SR-76, east of South Grade Road in unincorporated San Diego County. For reasons still under investigation, the driver veered off the roadway and overturned multiple times, CHP said.
