OAKLAND — One of seven men wounded in a drive-by shooting Saturday night in East Oakland where investigating officers were also targeted by gunfire, has died from his injuries, police said Wednesday.

He was identified as William Chavis, 35, of Oakland. He died at 7:59 p.m. Tuesday at a hospital.

Police said Chavis was in a car in the 7700 block of Bancroft Avenue about 11:30 p.m.Saturday when a gunman shooting from a car began firing at a group of people.

Six men on the street were wounded and Chavis was the only one in a car. Ages of the victims ranged from 24 to 45. At least one has been released from a hospital.

Sgt. Michael Cardoza said police are not sure of the motive for the attack but don’t believe Chavis was an intended target.

More than a dozen officers and a civilian crime scene technician also came under fire about 12:30 a.m. Sunday as they were doing follow-up work in the area. Officers used vehicles and fences as cover and no one was injured, even though officers reported hearing bullets whiz by them.

No one has been arrested in either shooting and police don’t have any evidence the two shootings were connected.

The death brings to 59 the number of homicides investigated by Oakland police this year. Last year at this time police had investigated 79 homicides.

Police and Crime Stoppers of Oakland are offering up to $50,000 in reward money for information leading to the arrest of suspects in the two attacks. Anyone with information may call police at 510-238-3821 or 510-238-3326 or Crime Stoppers at 510-777-8572.
