A fire spokeswoman says blame the crows for a "suspicious powder" scare at a Washington state intersection that detoured traffic for more than an hour. The Snohomish County Fire District 1 hazardous materials team responded Tuesday to a report about an unknown white powder in the roadway in Edmonds. A witness finally told the crew that a couple of crows were to blame. They said a woman was going jogging when she noticed the birds dragging a bag of white flour. The woman took the bag away from the birds, put it in a garbage can and kept running. It took firefighters about an hour to clear the scene.
