A federal grand jury has indicted Calvin M. Eriksen, 47, of Brookfield, Wisconsin, on charges of distributing child pornography. The indictment was returned on August 12, 2025, according to Richard G. Frohling, Acting United States Attorney for the Eastern District of Wisconsin.

If found guilty, Eriksen faces a mandatory minimum sentence of five years and up to twenty years in prison. He could also be fined as much as $250,000 and would be required to register as a sex offender under both state and federal law.

The case is part of Project Safe Childhood, an initiative launched by the U.S. Department of Justice in May 2006 that focuses on fighting child sexual exploitation and abuse. Project Safe Childhood coordinates efforts among federal, state, and local agencies to identify and prosecute those who exploit children online and to rescue victims. More information about this initiative can be found at www.projectsafechildhood.gov.

Homeland Security Investigations offices in Milwaukee and West Palm Beach, along with the City of Brookfield Police Department, investigated the case. Assistant United States Attorney Megan J. Thomas will handle prosecution.

Authorities noted that an indictment is not evidence of guilt; Eriksen is presumed innocent until proven guilty beyond a reasonable doubt at trial.

“An indictment is only a charge and is not evidence of guilt.  The defendant is presumed innocent and is entitled to a fair trial at which the government must prove him guilty beyond a reasonable doubt.”
