SAN PABLO — California Highway Patrol investigators are working to find the suspect in a collision and shooting that left a male injured on Interstate 80 late Saturday, authorities said.

Just before 11:20 p.m. Saturday, dispatchers received word of a collision between a black Dodge Charger and silver Honda Civic and a pedestrian walking westbound in eastbound I-80 lanes east of the San Pablo Dam Road over-crossing, the CHP said in a statement Sunday.

When officers arrived, they found a man, identified only as a Hayward resident, lying atop a concrete center divider. He told them he was driving the Charger when another vehicle began pursuing him, with both vehicles driving recklessly in traffic.

Moments later, the Charger struck the Civic in the roadway’s No. 4 lane, disabling both vehicles. The Charger’s driver drove a quarter-mile east before stopping in the No. 1 lane, getting out and managing to cross all lanes before beginning to walk westbound along the right shoulder.

At that point, the driver of the pursuing vehicle got out and fired three or four shots, hitting the man in his leg at least once. The man fled, running back across eastbound I-80 lanes, but was hit by at least one vehicle and suffered major injuries. He was taken to an area hospital for treatment, and is expected to fully recover, the CHP said.

Officers issued a Sig-alert that closed westbound I-80 lanes for about 45 minutes and eastbound lanes for about 2 hours and 15 minutes. San Pablo police helped shut down the San Pablo Dam Road off-ramp while CHP officers diverted traffic off and back onto I-80 at the El Portal on-ramp.

After a trio of East Bay freeway shootings during a three-day span in March, the CHP said they were reviewing ShotSpotter logs and surveillance-camera footage.

In a statement then, the CHP added that its Golden Gate Division had investigated 185 freeway shootings since Nov. 1, 2015 that ended in 65 injuries, including nine fatalities, with thirty-four people arrested in connection with one or more of those shootings.

Anyone with information should call the CHP’s Golden Gate Division at 707-917-4491.
