On September 25, 2006, KSCO and KOMY received an envelope containing white powder. The envelope, which had no return address and contained no letter, was addressed to "AUNTIE KSCO" in handwriting described by Program Director Rosemary Chalmers as "chicken-scratch." Emergency response teams arrived on scene, and all KSCO personnel in the building were evacuated by a HazMat crew. By the evening of Tuesday, September 26, an FBI lab had determined that the powder was inert, and KSCO/KOMY's broadcast studios were deemed safe. Regular broadcasting resumed at 8:00 PST that evening. None of the four people who came in contact with the envelope have experienced symptoms of any illness.
