(Eaton, OH)--An Eaton middle school teacher is now at the center of a criminal investigation after having been accused of sexually abusing one of her students.  The alleged victim told investigators that multiple encounters happened 11 or 12 years ago.  That person is now an adult.  As of Thursday morning, no criminal charges have been filed.  "We're really just getting into what the allegations are and getting into our investigation so that we can determine what occurred," said Preble County Sheriff Mike Simpson.  Once the investigation is complete, a report will go to the prosecutor’s office.  The teacher was still listed as a faculty member at Eaton Middle School on the school’s website Thursday morning.
