One man died and another was injured in a shooting on U.S. Highway 101 in San Francisco on Monday night, the California Highway Patrol said.
Officers initially responded to the highway's southbound lanes near Cesar Chavez Street around 9:30 p.m. for a report of a vehicle crash, according to the CHP.
Investigators soon learned that prior to the crash, the two victims, who are siblings, were in a black Buick when a shooter in another vehicle shot them on the highway.
The 30-year-old driver suffered gunshot wounds to his abdomen and lower body. He died from his injuries, CHP officials said. The 28-year-old passenger suffered a gunshot wound to his lower body and was taken to a hospital, according to the CHP.
The San Francisco medical examiner's office is working to identify the victim who died.
A description of the shooter and the suspect vehicle was not immediately available.
Detectives are asking anyone with information to call the CHP's tip line at (707) 917-4491.
