A Knox man pleaded guilty but mentally ill to two charges in Starke Circuit Court Thursday morning.
Frank Solberg, 44, pleaded guilty in a plea agreement with the state to charges of intimidation as a Class C felony and interference with reporting a crime as a misdemeanor. He admitted in open court that he threatened the life of his mother with a butcher knife if she were to call the police at the height of an argument. He also admitted that he ripped the telephone off the wall so she could not dial 911 to seek help from law enforcement.
