Pa. State Police corporal pleads guilty to making thousands of deepfake porn images, viewing child pornography
Stephen Kamnik abused his authority as a state police trooper to make pornographic images of his co-workers and women he interacted with on the job, prosecutors said.

A Havertown man pleaded guilty Wednesday to making thousands of pornographic, “deepfake” photos and videos of multiple women, including his relatives, a district court judge, and people he interacted with while working as a Pennsylvania State Police corporal stationed in Skippack.
Some of the photos found in his cache, prosecutors said Wednesday, were images depicting child pornography.
Stephen Kamnik, 39, entered an open guilty plea to sexual abuse of children, unlawful use of a computer, wiretapping, official oppression, and related crimes before Montgomery County Court Judge Todd Eisenberg.
He also pleaded guilty to receiving stolen property for a .22-caliber pistol found in his home that had previously been reported stolen.
His attorney, Charles Gibbs, declined to comment after the proceeding. Sentencing was deferred, and will take place in the coming months.
Kamnik, who has been a trooper since 2011, has been suspended without pay since his arrest last year, according to Senior Deputy Attorney General Jim Price, who prosecuted the case.
As part of his plea, Kamnik will have to register as a sex offender for 15 years, prosecutors said.
While searching Kamnik’s personal hard drive after his arrest last year, investigators discovered he had secretly recorded his coworkers and other women and filmed himself breaking into the women’s locker room at the barracks to rifle through his coworkers’ underwear.
The investigation into Kamnik’s actions began in November 2024, when state police officials noticed that the computer assigned to him had been using an unusually high amount of internet bandwidth, according to the affidavit of probable cause for his arrest.
Evidence on the computer showed that Kamnik had been connecting an external hard drive to it, on which they later learned he had been storing thousands of images of pornography, according to court filings.
Of those, 3,000 were deepfakes that Kamnik created by using AI image-generation tools to superimpose the photos of women — some he knew, some he had he met on the job — onto the bodies of naked women, the affidavit said.
To create those images, Kamnik used photos from the Pennsylvania Department of Transportation’s driver’s license database, as well as mug shots and other images stored in a law enforcement database, according to court filings.
Other files found on the computer depicted videos that Kamnik surreptitiously recorded on his cell phone in which he filmed his female coworkers at the barracks, focusing on their genitals and buttocks, the affidavit said.
He also recorded videos of women he met while on duty, including women involved in domestic-violence investigations and assault cases, according to the document.
