An Idaho man with a history of making bomb threats to courthouses is going to federal prison.

Kristopher Wrede of Boise, pleaded guilty and was sentenced Wednesday in U.S. District Court to one year for making a bomb threat. He will also serve three years of supervised release following his prison sentence.

Wrede was arrested on a Bonneville County warrant for charges that he made terroristic threats. The following day, Wrede called the Boise Suicide Hotline and told an employee that he had placed several bombs in the “federal courthouse” in Boise, which would be detonated that weekend. There were no bombs at the courthouse.

This isn’t the first time Wrede has been in trouble with the law. Wrede was arrested after a bomb threat was called into the Bannock County Courthouse.
