CEDAR RAPIDS | A Mason City man who pleaded guilty to possession child pornography was sentenced Thursday to more than 10 years in federal prison.

At the plea hearing, Jeffery Landheer, 47, admitted he knowingly possessed child pornography on a computer hard rive from 2009 to 2016, according to a news release. 

Landheer was sentenced 121 months in prison by U.S. District Court Judge Linda R. Reade in Cedar Rapids. Special assessments of $5,100 were imposed and Landheer must also serve a 15-year term of supervised release. 

He must comply with all sex offender registration and public notification requirements.

The case was prosecuted by Assistant U.S. Attorney Mark Tremmel and was investigated by the Mason City Police Department.

This case was brought forward 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 U.S. 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.
