(Radio Iowa) – A former Clarksville police officer has won a partial victory from the Iowa Court of Appeals on his sexual exploitation convictions. Prosecutors says Michael Tobin Junior started a relationship with a 14-year-old girl after investigating her case of online sexual exploitation. They say he showed her explicit photos and videos, and had sex with her at the police station.

A jury convicted Tobin of two felony counts of soliciting sexually explicit photos of minor, one felony count of promoting a sexually explicit video of a minor, and eight aggravated misdemeanors for possessing explicit images of minors. He was sentenced to not more than 15 years in prison.

Tobin appealed saying that some of the images were a part of his official duties. The Court of Appeals ruled that Tobin was not conducting his official duties when he showed sexually explicit images to the girl, but the evidence was insufficient to prove he wrongly possessed six images and they vacated those convictions.

Tobin is to be re-sentenced based on the five remaining counts.
