CHICAGO — A woman who is seven months pregnant and three other people were shot early Friday at a Grand Crossing apartment building.

Police were not sure what led up to the shooting, but it happened about 3:08 a.m. at a building in the 6300 block of South King Drive.

Two women, 22 and 29 years old, were inside an apartment when a gunman came up the back stairs from an alley and fired shots at them through the apartment’s open back door, police said.

The 22-year-old, who is seven months pregnant, was hit in her upper body, leg and arm and was in critical condition. The 29-year-old was hit in her leg and her condition was not available but she was listed as “stable,” police said. The women were taken to University of Chicago Medical Center.

A 20-year-old man was found shot in front of the building. He was hit in his foot and was taken to University of Chicago Medical Center. A 26-year-old man was shot in a hallway near the apartment unit. He was hit in his arm and he took himself to St. Bernard Hospital.

The men’s conditions were not available but they were listed as “stable,” police said. Twitter @BauerJournalism
