A dive team conducting an underwater survey of the Chicago River discovered close to 100 submerged vehicles on the riverbed, a find that captured widespread attention and raised questions about how so many cars ended up in one of the city’s most prominent waterways.
The vehicles range considerably in age, with some appearing to be decades old based on the level of deterioration observed by divers. The accumulation reflects generations of activity along the river, which runs through the heart of Chicago and has historically been the destination for vehicles pushed, driven, or dumped into the water for various reasons.
Some of the cars are believed to be connected to insurance fraud cases from past decades, when abandoning or sinking a vehicle was occasionally used to collect on a total-loss claim. Others may be the result of accidents, joyriding incidents that ended at the water’s edge, or deliberate disposal by criminal operations attempting to destroy evidence or dispose of stolen property.
The Chicago Police Department and other agencies were notified of the findings. Investigators expressed interest in running vehicle identification numbers against open missing persons cases, unresolved homicides, and cold case files, as submerged vehicles have historically been linked to crimes where a body or evidence was disposed of along with the car.
Environmental regulators also took interest in the discovery, as decades-old submerged vehicles can leach fluids, heavy metals, and other contaminants into waterways over time. The cost and complexity of recovering nearly 100 vehicles from a city river is substantial and any remediation effort would require significant coordination between multiple agencies.
The dive team that made the discovery was not conducting a criminal investigation but rather a routine or exploratory survey of the riverbed. The scale of what they found exceeded expectations by a significant margin.
