Convicted killer Colten Treu has been sentenced to another 110 days in jail on drug charges. Treu is already serving 54 years in prison for being high when he caused a wreck that killed members of a Girl Scout group cleaning up the roadside. That was in Chippewa County. Treu was being prosecuted in Rusk County this time after he admitted he was smoking pot before wrecking a company truck. Drugs were found in that truck. He will serve the drug sentence concurrently with the much-longer sentence for four counts of homicide by intoxicated use of a motor vehicle.
