The U.S. Postal Service and FBI are investigating the origins of a suspicious powder in the mail that forced the evacuation of a downtown Tacoma building Wednesday afternoon.
An employee at a Multi-Care building at 737 S. Fawcett Ave. found a mysterious substance in a package. Hazmat crews and Camp Murray’s civilian support team tested the powder and concluded that it was not dangerous. None of the 250 people in the building was harmed.
The powder has been sent to the CDC Laboratory Response Network for further testing, according to Jerry Styers, spokesman for the U.S. Postal Inspectors Service. Agents also are looking into who mailed the substance .
