One person was killed and three others seriously injured today in a head-on crash in San Jacinto.
The collision occurred about 4:30 p.m. on the westbound Ramona Expressway, near Warren Road, according to the California Highway Patrol.
A Toyota Scion and another sedan collided when one of the drivers crossed into oncoming traffic, a CHP officer said.
