OAKLAND -- A shooting late Friday night outside an East Oakland house where a birthday party was being held left two men dead and at least one other man wounded, police said Saturday.
Police were trying to determine if a fourth man who showed up later at a hospital with gunshot wounds was also a victim from the party.
One of the men killed was a 38-year Oakland resident. His name was not released.
The other man killed has not been identified.
The 52-year-old unidentified resident of the house where the party was being held was wounded and is in critical condition.
The shooting happened just after 11 p.m. in the 400 block of 105th Avenue in the Sobrante Park area.
Police said a birthday party was being held at the house -- they did not say for whom -- and more than a dozen people were outside the residence when some other people arrived. Moments later gunfire erupted, police said.
The unidentified man was pronounced dead at the scene. The 38-year-old man and the 52-year-old man were taken to a hospital where the younger man died early Saturday.
Officer Rob Rosin said so far police do not have a motive for the shooting and no arrests have been made.
Police and Crime Stoppers of Oakland are offering as much as $25,000 in reward money for information leading to the arrest of suspects.
