Three girls, including one as young as 5, were the unintended victims in a shooting Sunday night that wounded six people in the East Garfield Park neighborhood on the West Side.

About 10 p.m., the children were in a parked vehicle with a relative in the 3400 block of West Walnut Avenue when they were struck by gunfire, Chicago Police said. Someone in a passing car had opened fire on three other people who were standing on a sidewalk.

The children in the car, ages 5, 14 and 15, were not the targets of the shooting, police said.

The 14-year-old girl was shot in her chest, arm and abdomen, and was in critical condition at Stroger Hospital, police said. The 5-year-old girl was being treated at the same hospital with a gunshot wound to her arm. Her condition had stabilized. The third girl, 15 years old, was shot in her thigh, and was in good condition at Saints Mary and Elizabeth Medical Center.

The three people shot on the sidewalk included a 20-year-old woman. She was struck in her chest and arm, and was in serious condition at Mount Sinai Hospital, police said.

A 17-year-old boy was shot in his foot, and 26-year-old man was shot in his thigh, police said. They were both in good condition at Stroger Hospital.

Multiple shell casings were found at the scene, but police believe only one weapon was fired, according to Deputy Chief Al Nagode.

The shooter was in a black car with two other people, police said. They were last seen traveling north on Homan Avenue.

Police asked anyone with information about the shooting to contact detectives at (312) 744-8263.

“This is one that we need the help from the community on,” said Nagode.
