IDA GROVE, Iowa (AP) – A former substitute teacher and coach has pleaded guilty to having sexual relationships with students at two northwest Iowa high schools. Online court records say 33-year-old John Tietsort, of Battle Creek, entered the pleas Monday in Ida County District Court to two counts of sexual exploitation by a school employee. His sentencing is scheduled for May 15.

Prosecutors say Tietsort had a sexual relationship October 2015 through June 2016 with an 18-year-old female student at Odebolt-Arthur and Battle Creek-Ida Grove High School, where Tietsort was a substitute teacher and assistant football coach. Prosecutors also say Tietsort had a sexual relationship last year with a 17-year-old female student from Maple Valley-Anthon Oto High School, where Tietsort also was a substitute teacher.
