ST. LOUIS • A woman and two girls, 13 and 16, were injured when a shootout erupted at a St. Louis apartment complex Thursday afternoon.

The girls both suffered graze wounds. The 16-year-old was grazed in the leg, while the 13-year-old was grazed in the head. The woman, 31, was shot in the arm, police said. A witness said the woman was pregnant.

They were all taken to a hospital, where their conditions were not available.

They were struck when a gunfight broke out about 12:45 p.m. in the 5800 block of Selber Court on the western edge of the city.

People in an SUV fired shots at a man there, police said. Those shots are believed to have hit the victims.

Ashley Kimble, 27, lives in the Hillvale Apartments and said she had seen Thursday’s shooting.

“They pulled over and their door flung open and they started shooting,” Kimble said. “The pregnant woman was shot, and her 13-year-old daughter. She got caught in the crossfire.”
