CEDAR RAPIDS – A Lansing man who threatened to kill an Allamakee County Sheriff’s deputy in 2011 pleaded guilty in federal court last week.

Kenneth Haag, 26, pleaded guilty to one count of using a telephone to transmit an interstate communication threatening to injure another person Friday in U.S. District Court.

According to a plea agreement, Haag admitted he called the sheriff’s office Nov. 9, 2011 and threatened to kill a deputy. He threatened to kill the deputy more than once in the same phone call and then called later the same day and threatened to shoot a judge. Haag was in Chicago at the time the calls were made.

Haag also sent faxes, e-mails and made other telephone calls between November 2011 and January 2012 to the Allamakee Sheriff’s Office, clerk of court and judges in the county, according to court documents. In several of the communications, Haag made threats to injure or kill county officials or judges. Haag said he was frustrated with what he called his prior mistreatment by the courts, law enforcement and others. He admitted his statements could have been considered threatening.

Sentencing hasn’t been set at this time. Haag faces up to five years in prison and a $250,000 fine.
