A Montgomery County judge sentenced Pennsylvania State Police Cpl. Stephen M. Kamnik to five to 10 years in prison on Monday, followed by seven years of probation, Attorney General Dave Sunday announced. The judge designated Kamnik a sexually violent predator, requiring him to register as a sex offender for life.
Kamnik, 40, pleaded guilty to nine felonies and five misdemeanors. The charges included sexual abuse of children, unlawful use of a computer, receiving stolen property, invasion of privacy and official oppression.
Investigators found that Kamnik used state-owned computers to create AI-generated pornography depicting Pennsylvania residents. He created some of the material at state police barracks in Montgomery County. Investigators also found that he used JNET, a restricted law enforcement database, to obtain hundreds of photographs for personal use.
Kamnik secretly filmed and photographed people, including coworkers, and possessed child sexual abuse material. Investigators recovered a video he unlawfully recorded of a Montgomery County magisterial district judge during a court proceeding. They also found a stolen .22-caliber firearm in his vehicle during a search in January 2025.
The Office of Attorney General’s Public Corruption and Child Predator sections prosecuted the case.
