California house party shooting not gang-related

Authorities say a fatal shooting at a party at a home in Long Beach isn’t believed to be gang-related though it was likely a targeted attack.

Police say in a news release they are seeking the gunman, who had his face concealed as he opened fire from an alley behind the home, and potentially additional suspects. The gunman then fled in a getaway vehicle.

Officials say three men were killed and nine people injured by the gunfire. The surviving victims' conditions weren’t known.

About 25 people were at the house party late Tuesday night, including a group of co-workers.

Police don’t believe the shooting was a random act of violence.
