A Nebraska man has been given jail time for allowing his son to stay at his home after escaping from a minimum-security prison in South Dakota.

Robert Thorngren, of South Sioux City, was sentenced Monday in Dakota County Court to 220 days in jail on a misdemeanor charge of accessory to a felony. He must pay a $500 fine.

The 45-year-old Thorngren was arrested in March after his son, 30-year-old Travis Thorngren, went missing from the South Dakota State Penitentiary in Sioux Falls. He had been serving a five-year sentence on a grand theft conviction in Lincoln County.

Travis Thorngren pleaded not guilty to criminal impersonation. He is accused of giving a fake name when he was arrested.
