The victim was in a Cadillac at the intersection of San Pablo and Macdonald avenues at about 4 p.m. when a full-sized vehicle drove up.
One of the two males in the second vehicle got out, walked over to the victim and fired several rounds from a handgun at point blank range, striking the victim multiple times, Gagan said.
After being shot, the driver accelerated into the intersection, striking another vehicle, Gagan said.
The two vehicles crashed at the southeast corner of San Pablo Avenue, Gagan said.
The victim was in critical condition when he was airlifted to a local trauma center.
San Pablo Avenue, a major commute artery, is shut down and rush-hour traffic is mounting behind the closure, Gagan said.
