In June 2015, a local math teacher was charged with second-degree rape in connection with an alleged inappropriate relationship with a Bethel student. On Friday, that defendant pleaded guilty in the case and was sentenced.

Martin Ray Hertz, 49, Tecumseh, was charged in Pottawatomie County District Court, with charges alleging he had sexual intercourse with a 16-year-old female student who was under the legal custody or supervision of a public school system while he was an employee of the same public school system. The alleged incident occurred on or between June 1-3, 2015, the filing reads.

During Friday's pre-trial docket, Hertz withdrew his previous plea of not guilty and pleaded guilty. He waived a pre-sentence investigation and received a 10-year suspended sentence, the docket records show. He will be supervised through the Department of Corrections.

Charges in this case were the result of an investigation conducted by the Pottawatomie County Sheriff’s Office.

The investigation was launched after a student approached another teacher with concerns of a possible inappropriate relationship between Hertz and the teen, so that teacher reported the information to law enforcement.

During the investigation, Sheriff’s Detective Ken VanDuser searched cell phones belonging to Hertz and the teen and noted there were several text messages between the then-eighth grade math teacher and the 10th grade student.
