A former medical professional from Wauwatosa, Wisconsin, has been sentenced to six years in federal prison for crimes involving child sexual abuse material and attempted exploitation of a minor, federal authorities announced.
On January 29, 2026, Dr. Calvin Eriksen, 47, was sentenced to 72 months in prison by U.S. District Judge Brett H. Ludwig, according to United States Attorney for the Eastern District of Wisconsin Brad D. Schimel. The sentence follows an investigation that uncovered disturbing online activity involving the sexual exploitation of children.
The case began after four CyberTips were submitted to the National Center for Missing and Exploited Children (NCMEC). The tips flagged multiple user accounts on the Kik messaging platform that were involved in receiving and distributing child sexual abuse material (CSAM). Investigators traced the accounts to Eriksen, leading to search warrants executed at both his residence and workplace.
During those searches, law enforcement officers discovered CSAM, including images depicting the abuse of very young children, including infants and toddlers. Authorities also learned that Eriksen had been communicating online with an undercover law enforcement agent who was posing as the mother of an eight-year-old girl. According to court records, Eriksen repeatedly expressed a desire to sexually assault the child and sent the undercover agent a nude photograph of himself.
At sentencing, Judge Ludwig described Eriksen’s conduct as deeply disturbing. The judge emphasized that crimes involving CSAM do not exist in isolation, noting that the demand for such material fuels a market that results in the ongoing abuse of children. Judge Ludwig stated that Eriksen’s actions contributed directly to that cycle of harm.
In addition to his prison sentence, Eriksen will serve seven years of supervised release once he completes his term of incarceration. He will also be required to register as a sex offender under both state and federal law.
United States Attorney Brad Schimel underscored the seriousness of the case and the government’s commitment to protecting children. “We have no higher priority in the criminal justice system than to protect children,” Schimel said. “This case demonstrates the troubling reality that people who prey on children for sexual gratification can come from all walks of life.”
Brookfield Police Chief Christopher Garcia also addressed the impact of the case, calling it a stark reminder of the lasting harm caused by sexual exploitation crimes. He praised the cooperation between local and federal agencies, stating that such partnerships are essential to holding offenders accountable and safeguarding communities.
The investigation was conducted by Homeland Security Investigations offices in Milwaukee, Wisconsin, and West Palm Beach, Florida, in collaboration with the Brookfield Police Department. The case was prosecuted by Assistant United States Attorney Megan J. Thomas.
The prosecution was part of Project Safe Childhood, a nationwide initiative launched by the U.S. Department of Justice to combat the exploitation and abuse of children. The program coordinates federal, state, and local resources to identify offenders, rescue victims, and prevent online exploitation.
