White powder probed
NEW CASTLE, Pa. -- Authorities are investigating the origin of white powder that fell out of a letter as it was going through the Cascade Street post office. New Castle police said this morning that the powder fell out of an envelope that was ripped by a sorting machine Friday night. Postal authorities shut down that section of the post office and contacted Lawrence County Emergency Management Director Sharyn Critchlow, who authorized sending a hazardous materials group to the post office to take a sample and clean it up. Police said the envelope was addressed to someone in Imperial, Pa. The return address was fictitious, they said. Police said the investigation was turned over to the U.S. Postal Service.
