Shooting shuts down freeway in S.F.

Two men were shot in a car Saturday afternoon on Interstate 280 at Highway 101 in San Francisco, California Highway Patrol officials said.

Northbound I-280 to southbound U.S. 101 were closed while officers investigated the shooting, which was reported shortly before 4:30 p.m, and collision, officers said.

The roads reopened at around 6 p.m., said California Highway Patrol Officer Vu Williams.

Both victims are in their 20s; one was shot in the torso and leg, and the other in his head and neck area, San Francisco Police Officer Albie Esparza said in a statement. The victims were taken to San Francisco General Hospital and are expected to survive.

The men were conscious and sitting on the highway outside the gray Mazda they were in when officers arrived at the scene, Williams said. “When the vehicle was shot, the driver went forward and the hit the vehicle in front of him,” he said, adding that the other car’s occupants were uninjured.

Esparza said the suspect or suspects fled southbound on U.S. 01. He said officers did not have a description of the getaway vehicle.

The CHP is investigating the collision and San Francisco police are investigating the shooting.
