At least six people were wounded in a shooting Friday inside a South Side apartment.

The shooting started at 9:08 p.m. during a gathering inside an apartment in the 6500 block of South King Drive and spilled out into the hallway, according to Chicago police.

Police said one of the victims, a 23-year-old woman, was armed with a handgun. She was taken to Stroger Hospital in critical condition with gunshot wounds to the back, shoulder, head and abdomen.

A 14-year-old girl with gunshot wounds to the back, shoulder and lower backside and a 15-year-old girl with gunshot wounds to the leg and foot were both taken to Comer Children’s Hospital, according to police. The younger girl was in critical condition while the older girl was in good condition.

Another 14-year-old girl was shot in the leg and taken to Stroger Hospital in good condition, police said.

Chicago Fire Department officials said all three girls were in serious-to-critical condition.

A 20-year-old man with gunshot wounds to the face, chest and leg and an 18-year-old man with multiple gunshot wounds to the leg were both taken to the University of Chicago Medical Center in critical condition, police said.

At the shooting scene, police vehicles and crime tape were stretched across the 65th Street entrance of the Parkway Gardens Homes.

Evidence technicians and officers filtered in and out of a building and up to the third-floor apartment where the shooting happened. Valentine’s Day decorations could be seen through the window of the apartment under the shine of detectives’ flashlights.

Neighbors gathered outside, lightly dressed and shivering through the cold. Others came out a few at a time, climbed into vehicles, and left. One family with two small kids and a baby appeared to be leaving a party and were holding Valentine’s Day balloons.

Details about the circumstances of the shooting are unknown as Area Central detectives continue to investigate, police said.
