HARRISBURG, PA — A Pennsylvania State Police corporal was sentenced Monday to five to 10 years in prison for misusing government computers and restricted law enforcement databases, creating sexually explicit images of women using artificial intelligence, and possessing child sexual abuse material and a stolen firearm, in a public corruption case involving misconduct on state time and equipment.
Stephen M. Kamnik, 40, also received seven years of probation after pleading guilty to 14 criminal charges, including nine felonies and five misdemeanors, according to Pennsylvania Attorney General Dave Sunday.
A Montgomery County judge designated Kamnik a sexually violent predator during Monday’s sentencing, requiring him to register as a sex offender for life.
The convictions stemmed from an investigation that uncovered years of unauthorized computer activity, including the use of Commonwealth-owned devices and secure government databases to obtain photographs of women for personal purposes.
Investigators determined that Kamnik used artificial intelligence tools to generate sexually explicit images depicting female Pennsylvania residents, including activity conducted at a Pennsylvania State Police barracks in Montgomery County.
The investigation also uncovered evidence that Kamnik secretly recorded or photographed individuals, including coworkers, and possessed child sexual abuse material.
A search of his cellphone and an external hard drive recovered from his home revealed that he had accessed the Pennsylvania Justice Network, known as JNET, to obtain hundreds of photographs of women.
JNET is a secure information-sharing system used by authorized criminal justice and government personnel. Kamnik’s use of the database for personal purposes violated its access policies.
Investigators also recovered an unauthorized video recording of a Montgomery County magisterial district judge during a court proceeding. Kamnik had edited the recording for what authorities described as apparent sexual purposes.
The investigation extended beyond computer-related offenses.
During a January 2025 search of Kamnik’s vehicle, authorities discovered a stolen .22-caliber firearm, resulting in a felony receiving stolen property charge.
Kamnik pleaded guilty to four felony counts of unlawful use of a computer, along with felony charges of sexual abuse of children, receiving stolen property, unlawful duplication, interception or unlawful use of communications, and criminal trespass.
His five misdemeanor convictions included invasion of privacy, official oppression, tampering with evidence, misapplication of entrusted property and unlawful use of an audio or video recording device in court.
The charges followed an investigation conducted by the Pennsylvania State Police Internal Affairs Division and the Attorney General’s Office.
State Police filed charges against Kamnik in 2025 in consultation with state prosecutors.
“This high-ranking public servant betrayed his oath and committed numerous crimes — many while on the job when he was supposed to be serving his community,” Sunday said.
The case raised questions about the misuse of government technology and access to confidential information by law enforcement personnel entrusted with restricted databases.
The convictions included official oppression, reflecting the criminal consequences of Kamnik’s misuse of his position, along with offenses involving unauthorized recordings and the handling of government property.
The Attorney General’s Office prosecuted the case through its Public Corruption and Child Predator Sections.
