OAKLAND - A 33-year-old man was shot to death in East Oakland Wednesday night becoming the city's 110th homicide of 2012, the same number as all of last year, authorities said.

Police said the fatal shooting, that happened about 9:39 p.m. Friday in the 5900 block of Hilton Street, was not related to a wild shoot out in the westbound lanes of Interstate 580 near Seminary Avenue about an hour earlier that left two cars riddled with bullets but so far no victims found.

The man slain on Hilton Street was identified Thursday by police as Jose Rivera Estrada, a cook who lived in another part of East Oakland.

Officer Rob Rosin said police responded to reports of gunfire in the area and found Rivera Estrada lying on the sidewalk. He was pronounced dead at the scene.

Rosin said police still are not sure what Rivera Estrada was doing in the area and don't have a motive for the killing or suspects in custody.

Police said he may have been on his way home from his job at an Alameda restaurant but would not identify the restaurant until they have a chance to talk to others who work there.

Last year at this time there were 103 homicides in Oakland. Besides having 110 total homicides in 2011, Oakland also had the same number in 2009.

Police and Crime Stoppers of Oakland are offering up to $10,000 in reward money for information leading to the arrest of the killer in Wednesday's shooting. Anyone with information may call police at 510-238-3821 or a tip line at 510-773-2805. Tips can also be sent anonymously via text message. Text to 888-777 and include the words TipOaklandPD.

The freeway shooting happened about 8:40 p.m. Wednesday in the westbound lanes of I580 near the Seminary Avenue offramp.

Two vehicle were found riddled with bullets but no victims were present and none showed up later at hospitals. Investigators were trying to determine who owned the vehicles.

Because of similar shootings in the past on freeways, police said they cannot rule out the possibility the apparent gunfight was either drug related or involved rival gangs.

The westbound lanes of the freeway were closed until about 11:30 p.m. while officers conducted their investigation.

In a non fatal shooting Wednesday, a man suffered a minor wound when he was shot about 6:30 p.m. in the 2900 block of Broadway. The victim was treated at the scene and released.

Police did not release a motive in the shooting and said no arrests were made.
