“We acknowledge the substantial public interest due to the law enforcement activity and road closures. The engagement of specialized federal, state, and local resources was vital for safely handling the scene and ensuring public safety. We appreciate the public’s patience and cooperation during this time,” stated the federal officials.
The investigation necessitated the closure of I-290 for almost nine hours, causing significant disruption to commuters.
From the vantage point of Chopper 7, the scene revealed a Volkswagen SUV stranded in the middle lane, its windows shattered by the explosion. A bomb squad unit from the Cook County Sheriff’s Office was observed with weapons drawn, meticulously examining the vehicle.
The Cook County Medical Examiner’s Office said a man died in the incident. He has not yet been identified.
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.
