WESTCHESTER, Ill. — Authorities have released the identity of the man who perished in an explosion that led to the closure of Interstate 290 in the western suburbs for several hours on Thursday.
The Cook County Medical Examiner’s Office has named the deceased as 47-year-old Jorge Vaca from Cicero.
The explosion occurred around 10 a.m. near Mannheim Road, and federal officials have confirmed that it was an isolated incident, unrelated to any other events on that day.
Authorities have indicated that no other individuals are believed to have been involved in the incident.
“We understand the considerable public interest in the law enforcement activities and road closures. The situation required the expertise of specialized federal, state, and local teams to manage the scene safely and protect public safety. We appreciate the public’s patience and cooperation during this time,” federal officials stated.
The investigation led to the closure of I-290 for almost nine hours on Thursday.
Chopper 7 flew above the scene as a Volkswagen SUV in a middle lane sat with its windows blown out. A bomb squad unit from the Cook County Sheriff’s Office with guns drawn appeared to investigate the SUV.
On Thursday afternoon, an evidence tent was erected around the SUV. Evidence markers were also strewn across the highway as local and federal agents descended on the scene.
The Bureau of Alcohol, Tobacco, Firearms and Explosives and Drug Enforcement Administration Chicago Field Division were also involved in the investigation.
Federal officials said there is no known threat to public safety.
Full statement from federal officials:
“Following a coordinated investigation led by the FBI and ATF with instrumental support from a number of federal, state, and local law enforcement agencies and emergency responders, investigators have determined that the June 4, 2026, incident on I-290 near Mannheim Road was an explosion that resulted in the death of one individual. No evidence was found to indicate this was connected to any other event or that any other individuals were involved.
Additional details regarding the identity of the decedent and manner of death will be released by the Cook County Medical Examiner.
We recognize the significant public interest generated by the law enforcement response and roadway closures. The involvement of highly specialized federal, state, and local resources was necessary to safely process the scene and ensure public safety.
