RICHMOND -- One man was killed in a freeway shooting Saturday afternoon that closed all eastbound lanes of Interstate 580 and caused a major backup for weekend drivers, according to the California Highway Patrol.

The incident occurred at 12:39 p.m., when a blue Ford sport utility vehicle was struck by gunfire from another car and crashed into the center divide just west of the Regatta Boulevard offramp.

When officers arrived, they found Deonta Broussard, a 31-year-old San Francisco resident, who had been shot at least once inside the SUV. Broussard was pronounced dead at the scene.

The cause of the shooting is under investigation, but Richmond police do not think it is tied to road rage.

"We don't know what the motive of the shooting was but believe that the victim was targeted," Richmond Police Lt. Andre Hill said.

Information on the shooter's car was not available late Saturday.

All lanes were reopened shortly before 5 p.m., according to the CHP.
