A Sigourney, Iowa man is facing felony sexual assault charges for a rape allegation that dates back more than a year. Donald Dean Herr II, 54, faces one count of Second Degree Sexual Abuse.

According to the Iowa Department of Public Safety, DCI agents began the investigation in March of 2016.

A female resident of Keokuk County filed a complaint that she had been assaulted by Herr. That investigation came to an end last Friday with Herr’s arrest.

Herr has since posted a $50,000 bond and has been released.

He is scheduled to make his initial court appearance on August 28. If Herr is convicted, he faces up to 25 years.
