One person was killed and three others were wounded in a shooting at a crowded party in Los Angeles, authorities said.
The shooters were believed to be two gunmen who walked up to the party late Sunday in a residential area of Hollywood near the Sunset Gower Studios.
Officers who were in the area heard numerous shots fired and went to the scene, where they found the four shooting victims and "an unruly crowd," the Los Angeles Police Department said in a statement Monday.
"It is unknown if this is gang-related," the statement added.
