Overview
- The Cook County Medical Examiner identified the victim as 47-year-old Jorge Vaca of Cicero after the June 4 explosion on I-290 near Mannheim Road.
- The FBI and ATF led a coordinated probe that concluded the incident was an explosion and reported no evidence connecting it to other events or people.
- Bomb technicians and Illinois State Police processed a covered Volkswagen Atlas with blown-out windows while I-290 was closed for about eight to nine hours as evidence was collected.
- Limited reporting from unnamed law-enforcement sources says a commercial-grade firework mortar may have detonated inside the SUV and struck Vaca, but that account has not been formally confirmed by investigators.
- Authorities say a targeted cartel attack was ruled out early and investigators are focused on whether the detonation was accidental or intentional as autopsy and forensic work continue.
