The shooting happened in a parking lot outside of a Portillos restaurant near the mall. Video from the parking lot shot around 2:15 p.m. shows the area taped off. Officers seemed to focus their investigation around a silver SUV that had what appears to be clothes scattered around it.

The Lake County Major Crimes Task Force, which is working with Gurnee Police, said when the man was shot, a good Samaritan tried to nurse his injuries until paramedics arrived.
