Madison Man Sentenced for Failing to Register as a Sex Offender, Food Stamp Fraud, and Use of a Counterfeit Passport

MADISON, WIS. - Chadwick M. Elgersma, United States Attorney for the Western District of Wisconsin, announced that Mark F. Brummitt, 69, Madison, Wisconsin, was sentenced last week by Chief U.S. District Judge James D. Peterson to 6 years in federal prison for failing to register as a sex offender, illegally obtaining food stamps, and using a false passport. Brummitt pleaded guilty to these charges on February 4, 2026.

"Such systemic deceit will not be tolerated with regard to individuals seeking to steal benefits meant for low-income families that help them afford nutritious essentials for their health and well-being," said Inspector General John Walk for the U.S. Department of Agriculture Office of Inspector General. "USDA OIG is proud to support Project Safe Childhood. I thank and commend the work of this office, our law enforcement partners, and the U.S. Attorney's Office for the efforts to ensure that this dangerous individual is held accountable and will go to prison for his crimes."

Between 1989 and 2005, Brummitt was convicted of various sex offenses against children. He is required to register as a sex offender for the rest of his life. In late 2022, after having his supervised release revoked four times, Brummitt was released from federal prison. He spent time in Mexico and Mozambique. In February 2025, he returned to Wisconsin. He did not tell the Wisconsin Department of Corrections Sex Offender Registry about his change in residence and instead submitted paperwork stating he still lived in Africa.

While living in Wisconsin, Brummitt applied for and received $1,512 in Supplemental Nutrition Assistance Program (SNAP) benefits. He misrepresented his identity and his income when applying for those benefits. In August 2025, the Wisconsin Department of Health Services told Brummitt he needed to come to the local agency and present photo identification to continue receiving benefits. Brummitt presented a counterfeit passport.

Judge Peterson said that Brummitt stood apart from other offenders because of his "systematic deceit" and his resolute resistance to any form of supervision. The judge found Brummitt represented a threat to public safety because of his sexual interest in children.

The charges against Brummitt were the result of an investigation conducted by the Dane County Sheriff's Office, the U.S. Department of Agriculture - Office of Inspector General, the Social Security Administration - Office of Inspector General, Homeland Security Investigations, and the U.S. State Department. Assistant U.S. Attorney Megan Stelljes prosecuted this case.

This investigation was a part of Project Safe Childhood (PSC), a nationwide initiative to combat child sexual exploitation and abuse. Project Safe Childhood marshals federal, state, and local resources to better locate, apprehend, and prosecute individuals who exploit children via the Internet, as well as to identify and rescue victims.
