Unusual circumstances concerning a two-vehicle accident brought the FBI and the Joint Terrorism Task Force to investigate at an Omaha intersection Monday morning.
Following the collision between two cars at 40th and Leavenworth, one of the drivers became violently ill after ingesting a white, powdery substance that was in his car. Those who came in contact with the substance, a police officer, firefighter, and the two drivers were subjected to decontamination procedures and taken to the hospital. The man who ingested the substance remains hospitalized. His condition is not being released. The other three were treated and released. The substance irritated the skin and caused burning to nasal passages.
The Nebraska Medical Center identified the substance as cyanuric chloride, which is a type of tear gas according to the UNO Chemistry Department. "It is a heavy, acid-based substance," said Omaha Fire Department Batt. Chief Rob Trucha. "We are attempting to verify the substance so we can react to it appropriately."
Crews remain at the scene, spraying down the street and nearby vehicles.
