NORRISTOWN, Pa. — A Pennsylvania State Police corporal who possessed child sexual abuse material and used state computers to create AI-generated pornography of women was sentenced Monday to five to 10 years in prison.
Stephen M. Kamnik, 40, of Havertown, also secretly filmed and photographed women, including co-workers. Montgomery County Judge Todd Eisenberg added seven years of probation and designated him a sexually violent predator, which requires him to register as a sex offender for life, the state attorney general’s office said.
The sentence closes a case that began nearly two years ago, when investigators seized Kamnik’s work computer, and grew to more than 600 counts accusing him of abusing his position and state resources to target women.
“This conviction stains the many hard-working officers who abide by their oath,” Attorney General Dave Sunday said in a statement.
Kamnik pleaded guilty in April to 14 charges — nine felonies and five misdemeanors — including sexual abuse of children, unlawful use of a computer, receiving stolen property and official oppression. Prosecutors dropped hundreds of other counts, court records show.
According to the attorney general’s office, Kamnik used state-owned devices at a Montgomery County barracks to access AI tools and create pornography of numerous Pennsylvania women. He also improperly pulled hundreds of photos of women from JNET, a secured law enforcement database.
Prosecutors said he filmed women he encountered on duty and repeatedly entered a women’s locker room at state police barracks to take photos. Among the recordings was an unlawfully made video of a Montgomery County magisterial district judge during a court proceeding, which Kamnik edited for apparent lewd purposes.
A search of his vehicle in January 2025 turned up a .22-caliber handgun reported stolen in a 2010 Berks County burglary.
Kamnik, a trooper since 2011, was stationed at Troop K in Schwenksville when investigators seized a workstation hard drive holding thousands of pornographic files, some made with deepfake software. He surrendered in January 2025 on charges of unauthorized use of a computer and misapplication of entrusted property and was released on $1,000 unsecured bail.
In April 2025, those charges were withdrawn and replaced with the broader case, including counts tied to 24 individual female victims. Kamnik has been in custody since April 23, 2025, when bail was set at $500,000 cash, court records show.
State police suspended him without pay after his arrest.
Senior Deputy Attorney General James Price and Deputy Attorney General Kimberly Moraski prosecuted the case. Kamnik was represented by Fortunato N. Perri Jr.
