Three co-workers were sitting in a car in the Gresham neighborhood after finishing their shift at a Walmart store when gunfire erupted late Monday.

Two teenage women in the bronze Nissan sedan were killed and a teenage man was wounded after three men jumped out of a blue sedan and at least one of them opened fire, police say.

On Tuesday morning, Chicago police asked the public to help identify the suspects. Detectives think the shooting was “targeted,” but not gang-related.

“Was it a domestic? Was it something at work?” police Capt. Gil Calderon said at a news conference near the scene of the killing in the 7700 block of South Eggleston.

Brittani Rice, 18, and Senobia Brantley, 19, were shot shortly after 11:30 p.m. Monday. They were taken to St. Bernard Hospital where they were pronounced dead. A 19-year-old man in the Nissan suffered a gunshot wound to the shoulder.

“All three were friends,” Calderon said.

A police ShotSpotter gunshot detector alerted officers to the shooting.

Calderon said police don’t think the killing involved gangs. Each woman was arrested last year in separate downtown shoplifting incidents, but they have no serious crimes in their backgrounds. Calderon also noted that there’s no gang conflict in the area where the shooting occurred.

Police said the women and their co-worker were parked after leaving work at the Walmart in the 8300 block of South Stewart — about a mile away.

“We really don’t know why they stopped by here,” Calderon said.
