A Marshall County judge has sentenced a woman to 25 years after she admitting to molesting a 7 year-old girl. The case began last summer when Columbus, Indiana police contacted Plymouth Police about the allegations against 37-year-old Donna Adams. When interviewed by police, the woman admitted to at least one instance, which took place in a Plymouth hotel where Adams for several months in the fall of 2014. With good time credit, Adams is expected to serve just over 18 and a half of the 25 year sentence behind bars.
