STORM LAKE, IOWA – A former city hall employee in charge of a Northern Iowa town’s finances was sentenced today to seven years’ imprisonment for dealing child pornography images – including one video 90 minutes in length.
Brian Oakleaf (pictured at top), age 52, from Storm Lake, Iowa, received the prison term after a September 9, 2025, guilty plea to two counts of possession of child pornography.
Evidence at the plea and sentencing hearings showed that, from March 1, 2022, through July 29, 2024, Oakleaf received, distributed, and possessed child pornography, including depictions involving prepubescent minors, on two separate cell phones. In May 2024, law enforcement officers were investigating an online filesharing program and directed their focus on an IP address that was sharing child sexual abuse material. Investigators focused on the owner of the IP address, which led them to Oakleaf, a Storm Lake city employee.
On July 29, 2024, investigators searched Oakleaf’s home and his office at the Storm Lake City Hall. Officers seized cell phones and electronic devices. Analysis of Oakleaf’s devices showed that he used the filesharing program investigators were targeting. He also searched for many known child exploitation search terms to obtain child sexual abuse material. Evidence further showed that Oakleaf had used the alias Dan Dyle to look at and trade child sexual abuse material.
In the plea agreement, Oakleaf admitted he possessed a video that was over 90 minutes in length and over 20,000 images of child sexual abuse material on his two phones. The videos and images included depictions of toddlers, bondage, and sadistic and masochistic conduct.
This case was brought as part of Project Safe Childhood, a nationwide initiative launched in May 2006 by the Department of Justice to combat the growing epidemic of child sexual exploitation and abuse. Led by the United States Attorneys’ Offices and the Criminal Division’s Child Exploitation and Obscenity Section, Project Safe Childhood marshals federal, state, and local resources to locate, apprehend, and prosecute individuals who sexually exploit children, and to identify and rescue victims.
Sentencing was held before United States District Court Judge Leonard T. Strand. Oakleaf was sentenced to 84 months’ imprisonment and must serve a five-year term of supervised release following imprisonment. There is no parole in the federal system. Oakleaf must also pay $54,000 in restitution to the victims in this case and an additional $1,200 in fines and assessments. Oakleaf remains in the custody of the United States Marshal until he can be transported to a federal prison.
The case was investigated by the Iowa Division of Criminal Investigation and prosecuted by Assistant United States Attorney Kraig R. Hamit.
