The western Wisconsin man serving 54 years in prison for causing the deaths of four people – including three Girl Scouts – wants to withdraw his guilty pleas. Attorneys for Colten Treu filed the motion two weeks ago and a hearing is set for early March. Treu is expected to argue that he wasn’t told he was giving up his right to appeal the denial of his request for a change of venue. Treu was sentenced last March. Prosecutors said he was high when he lost control of his pickup, veered off the road, and hit the scouts who were picking up trash.
