OAKLAND -- A 23-year-old man was killed and two other men wounded Wednesday night in an East Oakland shooting, police said Thursday.

The name of the dead man, an Oakland resident, was not released pending notification of relatives.

The shooting happened about 9:35 p.m. in the 1200 block of 47th Avenue.

Police said the 23-year-old man and his 24-year-old friend, who is also from Oakland, were in a car driving on 47th Avenue when more than one gunman opened fire on the vehicle wounding both of them.

A 30-year-old Oakland man in another car was also wounded by gunfire.

The 23-year-old man was pronounced dead at the scene. The other two men were in serious but stable condition at a hospital Thursday.

Police said the slain man and his friend were the intended targets of the gunman and the other wounded man was an innocent victim.

Officer Eric Milina said police are trying to determine a motive for the shooting and no arrests have been made.

The killing was Oakland's 99th homicide of the year. Last year at this time there were 90 homicides in the city.
