Chemical discovery forces evacuation in Cheyenne
CHEYENNE, wyo – The discovery of a possibly explosive chemical at the state crime laboratory has forced the evacuation of several buildings in downtown Cheyenne.
Sgt. Rob Dafoe of the Cheyenne Police Department says that hazardous materials teams have responded to the scene, at the state Division of Criminal Investigations building on West 22nd Street.
The DCI is moving to a new building. Dafoe says that the discovery of the chemical during the move prompted authorities to evacuate the nearby Cheyenne Public Library and other area buildings on Monday afternoon.
Attorney General Bruce Salzburg oversees the DCI. He says officials at the State Office of Homeland Security told him the chemical is picric acid which had been in storage so long it had crystalized.
