GREAT BEND, Kan. (AP) — A former Kansas high school coach has pleaded no contest to sexual exploitation of a child after a nude picture of a minor was found on his cell phone.

The Great Bend Tribune reports that 55-year-old Todd Kaiser entered the plea Thursday in Barton County District Court. Barton County Attorney Amy Mellor says authorities obtained a search warrant in June and found the nude picture.

At the time, Kaiser was a physical education teacher at Eisenhower School. He also was a head cross country coach, winter weights coach, track head coach and driver’s education teacher for the Great Bend district. He had worked for the school system since 1987.

Sentencing is set for June 23.
