A large, late-night party spiraled into violence Sunday morning, resulting in one person being shot and the suspect or suspects fleeing and still at large.

Portland police responded to the shooting in the 0200 block of S.W. Hamilton Street at 4:35 a.m. The shooting apparently grew out of an altercation outside the party, police say. A house also was struck by bullets.

The victim's injury is not considered life-threatening.

The police department's gang enforcement team is involved in the investigation, though it has not been determined that the shooting was gang-related.

Friday night saw three shootings that police believe involved gang activity. One man was wounded. Police have not determined whether the Sunday-morning shooting is linked to any of the Friday gun violence. The investigation is continuing.

Portland police encourage anyone with information about a shooting to call 503-823-4106 or email gangs@portlandoregon.gov.
