Approximately one month after a jury found an Ames man and former North Polk High School teacher guilty of three counts of sexual exploitation by a school employee, his sentencing date has been delayed to next year.


Kevin Jacob Muehlenthaler, 29, is expected to be sentenced Jan. 4, after it was originally set for Dec. 20.


Muehlenthaler was charged in early February with four counts of sexual exploitation by a school employee after turning himself in at Story County Jail.


According to Story County Attorney Jessica Reynolds, Judge Steven Van Marel only submitted three counts to the jury, as he found there was not enough evidence to submit the fourth count.


Muehlenthaler was charged last fall after the victim stated a relationship between her and Muehlenthaler occurred from November 2013 through July 2014.


Court documents show the victim was a teacher’s helper in Muehlenthaler’s class. Muehlenthaler was a fifth-grade band teacher at the time, but court documents did not specify whether that was the class in which the student assisted Muehlenthaler.


Four sexual encounters were reported to police, two at Muehlenthaler’s residence, one at his friend’s house and another at an Ames hotel.


Muehlenthaler was employed at the North Polk district from August 2013 through June 2016. He worked in the Chariton school district from about that time to Sept 28, 2016, when he resigned.
