Suspicious envelope contained corn starch
Cheyenne, Wyo. – The Wyoming Highway Patrol says the powder contained in a suspicious envelope addressed to Gov. Dave Freudenthal has proven to be harmless corn starch.
Officers intercepted the letter at the state Capitol on Thursday. Sgt. Stephen Townsend, spokesman for the Highway Patrol, said Friday that a Wyoming Department of Health laboratory determined the powder is corn starch.
Federal officials say that more than 30 such letters have been received at various state capitols around the country this week.
The Postal Inspection Service, which is working with the FBI, noted that sending hoax letters can result in up to five years in prison.
