SAN DIEGO -- An 18-year-old man was hospitalized Wednesday with several gunshot wounds that he suffered when someone walked up behind him in Mountain View and opened fire, police said.

The victim was walking in the 400 block of South 38th Street around 7:40 p.m. Tuesday when the shooter approached from behind and fired several rounds, San Diego police Sgt. Bob Dare said.

The man was struck several times in the back and arms but is expected to survive, the sergeant said.

The shooter, who wore a gray shirt or jacket, fled in a black sport utility vehicle eastbound in the south alley of Oceanview Boulevard, Dare said.
