Joseph Kalamaris, 33, of Rosemont was found fatally shot inside a parked vehicle on the 900 block of North Avenue in Des Plaines on the afternoon of July 23, 2025. Family members discovered him and Des Plaines officers arrived about 4:25 p.m.; he was pronounced dead at the scene. Authorities described the death as a likely homicide and said the incident appeared isolated with no broader threat to the public.

Detectives have been building a timeline and canvassing the neighborhood. On August 11 a Des Plaines man was publicly named as a person of interest; officers attempted a traffic stop in Northbrook, the driver fled, and the vehicle was later located in Wheeling where the subject was taken into custody without incident at 10:17 p.m. He was released the next morning at 10:53 a.m. No arrests or charges have been announced and the investigation remains active.

Anyone with information about Joseph Kalamaris, his movements on July 23, or the area around North Avenue is asked to come forward.
