MASON CITY — A December sentencing is scheduled for a former Iowa State Patrol supervisor who admitted stealing prescription painkillers seized during criminal investigations. Court records say 32-year-old Michael Haugen has filed written pleas of guilty to misdemeanor charges of theft and tampering with records. His sentencing is set for Dec. 19. The records say Haugen has acknowledged removing pills from evidence bags about 18 times in up to eight different cases between late 2014 and April.
