The Allamakee County Sheriff’s Office is reporting the arrest of Jonathon Stuart Hilleshiem, 54, of Waterville on multiple sex-related charges involving a minor child over a number of years. The report also states that a criminal charge is merely an accusation, and defendants are presumed innocent until and unless proven guilty in a court of law.

July 20 of this year, Hilleshiem was arrested on four counts of Sexual Abuse in the 2nd Degree - Child Under 12, a Class B Felony; one count of Lascivious Acts with a Child, a Class C Felony; and one count of Incest, a Class D Felony. After the execution of search warrants following his arrest, Hilleshiem was additionally charged August 20 of this year with one count of Sexual Exploitation of A Minor - Possess Depiction of Minor in Sex Act, a Class D Felony, after it was discovered that he was in possession of photographs of the minor child.

According to court documents filed in the case, the charges resulting in the July 20 arrest stem from alleged acts that took place between January 1, 2014 and December 31, 2020 when the minor child was making visits every other weekend to Hilleshiem’s rural Waterville home. Those court documents further indicate that “there may have been over 100 acts of sexual abuse between 2014 and 2020.”

The Allamakee County Sheriff’s Office was assisted in the investigation by the Lansing Police Department, the Allamakee County Attorney’s Office, and Allen Child Protection Center in Waterloo. A pre-trial conference has been scheduled in the case for October 20 of this year in Allamakee County District Court, with a jury trial currently set for November 5 of this year. Hilleshiem is currently being held on $120,000 cash only bond.
