Registered sex offender arrested on multiple new child pornography charges

BUFFALO, N.Y.-U.S. Attorney Michael DiGiacomo announced today that John Peterson, 42, of Jamestown, NY, was arrested and charged by criminal complaint with distribution and possession of child pornography by a person with a prior child pornography conviction, which carry a mandatory minimum penalty of 15 years in prison, a maximum of 40 years, and a $250,000 fine.

Assistant U.S. Attorney Douglas A.C. Penrose, who is handling the case, stated that according to the complaint, in June 2025, the National Center for Missing and Exploited Children (NCMEC) received a CyberTip from the messaging app Kik that two files of suspected child pornography were uploaded between June 14 and June 16, 2025. The files were uploaded with the username “hardinny41_mkc” and were shared with other Kik users. On July 05, 2025, NCMEC received another CyberTip from Kik that a file of suspected child pornography was uploaded on June 28, 2025 by someone with the username, hardinny4_mf7” and had also been shared with other Kik users. Subsequent investigation traced the uploaded files to Peterson. On December 3, 2025, investigators executed a search warrant on Peterson’s person, seizing his cell phone. A forensic analysis identified approximately nine image files and five video files of suspected child sexual abuse material. Some of the images included infants, toddlers, and prepubescent children.

Peterson is a level 1 sex offender following a 2010 misdemeanor conviction in Carroll Town Court for Attempted Possessing a Sexual Performance by a Child Less than 16 Year of Age. He was subsequently convicted in 2023 in Chautauqua County Court of Possessing a Sexual Performance by a Child Less than 16 Years of Age and Criminal Possession of a Firearm.

Peterson made an initial appearance today before U.S. Magistrate Judge Jeremiah J. McCarthy and was held pending a detention hearing on April 2, 2026.

The complaint is the result of an investigation by Homeland Security Investigations, under the direction of Special Agent-in-Charge Erin Keegan and the New York State Police, under the direction of Major Amie Feroleto.

The fact that a defendant has been charged with a crime is merely an accusation and the defendant is presumed innocent until and unless proven guilty.
