WELLINGTON, Kan. (AP) — A former south-central Kansas band instructor has pleaded guilty to sexual exploitation of a child.

30-year-old Benjamin Olson entered the plea Thursday in Sumner County District Court. As part of the plea, Olson admitted to having a nude photo of a 17-year-old girl. In exchange, prosecutors dropped four other felony counts in the case.

Prosecutors will recommend Olson serve 16 months in prison when he’s sentenced July 25.

Olson was arrested in March. Police say he asked for nude photos and video from a student, of sending the student sexually explicit texts and fondling the girl.

Olson had been the band teacher for the middle school and high school at Wellington since 2015.
