A registered sex offender in Jamestown, NY, has been arrested on multiple child pornography charges. John Peterson, 42, was taken into custody after an investigation by Homeland Security Investigations, which began with a tip from the messaging app Kik in June 2025. The tip reported that two files of suspected child pornography were uploaded between June 14 and June 16, 2025, using the username “hardinny41_mkc”. The files were shared with other Kik users, leading investigators to Peterson.
Peterson, a level 1 sex offender, has a history of similar convictions, including a 2010 misdemeanor conviction in Carroll Town Court and a 2023 conviction in Chautauqua County Court for possessing child pornography and criminal possession of a firearm. The latest investigation found approximately nine image files and five video files of suspected child sexual abuse material on Peterson’s cell phone, including images of infants, toddlers, and prepubescent children.
Peterson made an initial appearance before U.S. Magistrate Judge Jeremiah J. McCarthy and was held pending a detention hearing on April 2, 2026. If convicted, he faces a mandatory minimum penalty of 15 years in prison, a maximum of 40 years, and a $250,000 fine. The case is being handled by Assistant U.S. Attorney Douglas A.C. Penrose.
The arrest highlights the ongoing efforts of law enforcement to combat child pornography and protect vulnerable victims. The National Center for Missing and Exploited Children (NCMEC) played a crucial role in the investigation, receiving CyberTips from Kik and providing critical information to investigators.
The case serves as a reminder of the importance of reporting suspicious activity and the need for continued vigilance in the fight against child exploitation. As the investigation continues, Peterson’s arrest sends a strong message that those who engage in such heinous crimes will be held accountable.
