In December 2023, during a separate investigation, deputies uncovered evidence that Boyer had sexually assaulted a child multiple times in Fremont County between 2020 and 2023. Sheriff Aistrope said “Following a thorough investigation, which led to multiple convictions of other suspects involved in other acts of sexual related offenses, in both state and federal court, Boyer was interviewed in August 2024. During the interview, he admitted to acts of sexual abuse, including offenses against minors dating back to the early 1980’s.”

Boyer was arrested on September 13, 2024, by the Fremont County Sheriff’s Office and initially charged with multiple offenses, including four counts of Sexual Abuse in the Second Degree, one count of Sexual Abuse in the Third Degree, and five counts of Incest. He was held on a $150,000 cash-only bond before sentencing.

As part of a plea agreement, Boyer pleaded guilty to two counts of Lascivious Acts with a Child, a Class C Felony, with an agreement for open sentencing. In Iowa, an open sentence means the court, rather than the prosecutor, determines the defendant’s punishment.

At sentencing, Fremont County Attorney Peter Johnson requested the maximum penalty allowed under Iowa law—two ten-year prison terms to be served consecutively. However, despite the State’s argument, Boyer was sentenced to two ten-year prison terms to be served concurrently. The court also imposed fines totaling $2,740.

Judge Reyes then suspended both the prison sentence and fines, deciding instead to place Boyer on probation for two years under the supervision of the Fourth Judicial District Department of Correctional Services.

As a condition of his probation, Boyer must reside at a residential treatment center until the Department of Corrections determines he has achieved maximum benefit. Additionally, he is required to register as a sex offender, submit to DNA profiling, and successfully complete Iowa’s Sex Offender Treatment Program, among other requirements.

Sheriff Aistrope said “The Fremont County Sheriff’s Office strongly objects to the court’s decision in this case. The sentence does not reflect the severity of Boyer’s crimes and fails to deliver justice to the victim and others affected. Lenient sentences for sexual offenses—especially against children—undermine public confidence in the legal system and may discourage other victims from coming forward.

“We stand with all survivors of sexual abuse, especially children, and commend their courage in seeking justice. It is essential that our legal system acknowledges the harm suffered by victims and the ongoing risk posed by offenders like Ronald Boyer.”

The case was investigated by the Fremont County Sheriff’s Office and prosecuted by the Fremont County Attorney’s Office with assistance from the Iowa Attorney General’s Office.
