SHEBOYGAN, WI (WHBL) - A Sheboygan Falls man charged with sexually assaulting a young girl was back in Sheboygan County Court for sentencing Tuesday and is now headed back to prison. Judge L. Edward Stengel sentenced 47 year old Andrew Leichtnam to 6 years in prison to be followed by 10 years extended supervision. Authorities said police were contacted last summer by a social worker and then interviewed the 9 year old victim and her mother. Leichtnam was in prison at the time, serving a two and a half year sentence for 9th offense drunk driving, but it was determined the incident occurred about 3 years earlier - prior to the time Leichtnam was incarcerated.
