A New Prague woman has been sentenced to 15 years in prison for threatening to kill several law enforcement officers. U.S. District Judge Paul Magnuson sentenced 47-year-old Kim Rolene Hutterer on Monday. She pleaded guilty in July to one count of threatening interstate communications and one count of mailing threatening communications. Hutterer admitted making a telephone threat to an employee at a federal prison in Virginia in 2010. The indictment also accused her of mailing letters threatening Vice President Joe Biden and an FBI special agent, who had arrested her 20 years ago for bomb threats against an airline.
