CASPER, Wyo. – Police say an unknown white powder that forced the evacuation of Casper Star-Tribune offices in Wyoming has been identified as cocaine.
Employees in the newspaper's Casper building were evacuated for about three hours Friday morning after a staff member opened an envelope containing the powder and a dollar bill.
The newspaper reports on its Web site that testing by police found that the powder was about a half tablespoon of cocaine.
Casper police Lt. Chris Walsh says the envelope was addressed to an employee and had a Denver postmark. The employee is not suspected of any wrongdoing.
Employees were allowed to return to the building after a precautionary bomb sweep.
Casper is about 145 miles northwest of Cheyenne.
