Police searched the 300 block of Walker Avenue in Highland Park after a shooting, prompting a shelter-in-place order for residents. Investigators described two people of interest—a man and a woman who were seen talking with the victim before the incident—and released images of them, urging the public to contact authorities if recognized. Residents were told to stay indoors, avoid opening doors to unexpected visitors, and call 911 with concerns, while officers deployed K-9 units and drones and set up perimeters. An injured person was transported to a local hospital, and investigators continued to work to identify suspects and gather information. By late evening, the shelter-in-place was lifted as officials suggested the suspects had likely left the area, though the investigation remains active. This remains a developing story with updates from local outlets.
