Minnesota Man Admits On Jail Call To Failing To Register As Sex Offender

MINNEAPOLIS, MN — A federal jury has convicted Randy Joe Fuller, 54, of failing to register as a sex offender after moving to Minnesota from Iowa.

Fuller, who was convicted in 1990 in Fillmore County of first-degree criminal sexual conduct for sexually assaulting a child, is required under federal law to keep his sex offender registration current until 2039.

He has three prior state convictions, in 2000, 2010, and 2013, for failing to do so.

Prosecutors said Fuller moved to Houston, Minnesota, in December 2024 without notifying state or federal authorities as required by the Sex Offender Registration and Notification Act. In January, police went to his home for a verbal altercation and discovered he was living in Minnesota without registering.

While in custody at the Sherburne County jail, Fuller admitted on a recorded call, "I am guilty of failure to register," authorities said.

"Sex offender registration laws exist for one reason—to protect our communities and our children from known threats," said Acting U.S. Attorney Joseph H. Thompson.

"When offenders ignore these requirements, they undermine a system designed to keep our families safe. Our duty is to protect children from those who prey on them, and we will use every power under federal law to do exactly that."

The case was investigated by the U.S. Marshals Service with help from the Bureau of Criminal Apprehension, the Houston Police Department, and the Iowa Division of Criminal Investigation.
