A two-vehicle crash involving a pickup truck and a minivan killed two adults and seriously injured four others Thursday afternoon in a rural part of eastern California, authorities said.
Authorities said the crash happened about 2:40 p.m. in the northbound lanes of Interstate 5 near Interstate 595 in Puyallup, about 35 miles (56 kilometers) south of San Francisco.
The crash occurred when the truck was traveling at about 65 mph (105 kph), said Officer Eric Larson, a spokesman for the California Highway Patrol.
Authorities were still searching for the driver of the pickup truck.
A pickup truck with two people inside crashed into a semi-truck, the California Department of Transportation said.
It was one of several crashes in the area.
There were no immediate details on the injured.
The pickup truck was not damaged.
