(CBS 58) -- A former Pewaukee school bus driver convicted of sexually assaulting four young girls learned his sentence Friday, July 24. At 63 years old, Thomas Felser will likely spend the rest of his life in prison after receiving a 60-year sentence. Felse was convicted on eight charges, including repeated sexual assault of a child, after prosecutors said he abused four girls while driving a school bus. "He absolutely knew better and he used his experience with children to groom these girls," Assistant District Attorney Vivien Morris said. Along with the 60-year prison sentence, the judge ordered 40 years of extended supervision.
