(Eaton, OH)--Court documents were obtained Tuesday that detail the allegations against Eaton High School band director Paul Bingle, who now faces eight criminal charges after alleged inappropriate relations with at least one female student.  According to the documents, another student alerted adults after witnessing troubling behavior by Bingle.  That witness provided investigators with chats through a social messaging app and said that one student would routinely show up an hour before band practice was to have started.  When the school superintendent and a detective went to question Bingle last Thursday, they found him in the band room with the door locked and with the lights off with one female student.  Bingle remains on leave from school and in the Preble County Jail.
