A former Alton man has been sentenced to 32 years in prison after being found guilty of predatory criminal sexual assault of a 10 year old child. 34 year old Garrett B. Rottau, formerly of the 100 block of East Elm Street, was found guilty in Madison County Court in September and sentenced on Thursday.
Rottau was a family friend who was supposed to be caring for the child, but instead sexually assaulted her on several occasions when she was 10 and 11. The now 17 year old testified against him during the trial. Rottau was sentenced to 8 years for each count and must serve at least 85-percent of the 32 year sentence. Prosecutors were seeking 60 years in prison. Circuit Judge Richard Tognarelli handed down the sentence.
