It all started from some sort of altercation between a black Lexus and a black Chevrolet Tahoe on the westbound 60 Freeway near Crossroads Parkway at around 8:30 p.m. Sunday, according to the California Highway Patrol.
As both vehicles continued to engage, they drove onto the southbound 605 Freeway. When they reached the Beverly Boulevard off-ramp, the driver of the Tahoe drove to the Lexus' left side and fired at least two rounds, striking both left-side doors of the Lexus.
The driver of the Lexus felt pain on his back and noticed blood on his shirt, CHP said. He exited the freeway and drove to a family member's residence and called 911.
The shooting victim, who was later identified by police as Ronald Winans Jr., was transported to USC Medical Center to be treated for a graze wound on his lower back.
The suspect remains at large. Investigators described the vehicle as a black Chevy Tahoe with a toolbox strapped to the trailer.
If you have any relevant information, you're urged to contact CHP.
