A 19-year-old woman is dead and two other victims have been hospitalized Wednesday morning following a triple shooting overnight in the Gramercy Park neighborhood of South Los Angeles.

The shooting occurred around midnight as the victims were standing outside amid a group of people near the intersection of South Western Avenue and West 91st Street, Los Angeles Police Department Detective Chris Barling said.

A man apparently walked up to the group and fired multiple rounds, striking a 19-year-old woman, a 19-year-old man and a 41 year-old woman, Barling said.

The 19-year-old woman was pronounced dead at the scene.

Emergency crews transported the other woman and the man to a local hospital with what were believed to be survivable injuries, Barling said.

The group was apparently attending a pre-Fourth of July BBQ when the gunman arrived and opened fire.

Investigators do not have a motive for the shooting but do believe the shooter, described only as a man in his late teens or early 20s, had some sort of gang affiliation.

None of the victims had any gang ties, Barling said.

The suspect ran to a nearby vehicle and drove away after the shooting. Investigators did not have a description of the vehicle.

Authorities plan to check nearby businesses for any surveillance video.
