OAKLAND -- A teenager killed in what police said could be a gang-related shootout in the Laurel district of East Oakland has been identified as Tyler Frank Jamison of Berkeley.

Jamison, 17, was shot to death about 10:30 p.m. on Saturday on the 4000 block of Quigley Street, police said Monday.

Police said there was a shootout between two groups when Jamison was shot along the street, located between Interstate 580 and MacArthur Boulevard. He died from his wounds at the scene.

Police are not releasing whether Jamison had a gun but said they don't think Jamison knew anyone in the area.

They also said they were trying to determine a motive for the killing but had not ruled out the possibility the shooting was gang related. No arrests have been made.

Police initially thought Jamison was 19 but said Monday that information was incorrect.

Jamison was enrolled as a junior last year in the Berkeley Unified School District, said schools spokesman Mark Copelan, but he was not currently enrolled in the district.

Authorities confirmed Jamison is the same person who was arrested and charged with two counts of attempted murder for a Dec. 23, 2011, afternoon shooting near Sacramento and Woosley streets in Berkeley. During the melee, five male juveniles, including Jamison, reportedly pulled out guns and fired at one another, injuring two of them.

Alameda County District Attorney Office spokeswoman Teresa Drenick said prosecutors dropped the charges against Jamison on June 13, 2012, because witnesses in the case refused to testify.

The killing was Oakland's ninth homicide of the year. Last year at this time there were 14 homicides in Oakland.

Police and Crime Stoppers of Oakland are offering up to $10,000 in reward money for information leading to the arrest of the killer. Anyone with information may call investigators at 510-238-3821, a tip line at 510-773-2805 or Crime Stoppers at 510-777-8572.
