Two men were fatally wounded and a third was injured Saturday night/early Sunday outside what the East Bay Times reports as an "all ages birthday party" at a downtown Oakland gallery. The two deceased victims were aged 20 and 22, according to the paper, and the wounded man is 24. None of the victims have yet been identified.

The shooting occurred following a dispute that apparently spilled out of the party at Prime Development, a gallery and retail shop that hosts events on the 300 block of 15th Street. Police responded to the scene at 12:53 a.m. today, and they found the injured man, who was struck by gunfire, a couple of blocks away.

The Chronicle reports that responding officers found many people fleeing the scene as they arrived.

The two men died at the scene, and a fourth man reportedly was injured after running into a plate glass window trying to flee.

Update: The East Bay Times reports that the two dead men have been identified as Craig Fletcher-Cooks, 20, and Terrence McCrary, 22. Fletcher-Cooks was shot inside Prime Development, where a party of 50 to 100 people was taking place, but at the time of the shooting, police now say there were as many as 300 people out in the street outside the gallery. McCrary was found near 15th and Webster Streets, and it remains unclear whether he knew Fletcher-Cooks, or where he was shot. A third man, age 24, was shot and ran several blocks away, to the 1700 block of Webster, where police found him. He is expected to survive.
