A Winterset man has pleaded guilty to sending threatening letters to several people. The U.S. Attorney for Iowa’s Southern District says William David Langford admitted to sending an envelope to an individual that contained a written death threat and a white powder he indicated was a harmful biological agent or toxin.
Langford also pled guilty to mailing threatening letters to nine other individuals or organizations in February of 2010. Langford will be sentenced on May 27th.
The charges carry the potential for prison time of up to five years and a quarter-million-dollar fine for each count.
