HARRISBURG, PA — A Pennsylvania State Police corporal pleaded guilty Wednesday to multiple felony and misdemeanor charges related to misuse of government systems, illegal recordings, and possession of child sexual abuse material, the Pennsylvania Attorney General’s Office announced.
Stephen M. Kamnik, 39, entered guilty pleas in Montgomery County Court to 15 charges, including nine felonies, according to prosecutors.
The charges include unlawful use of a computer, sexual abuse of children, receiving stolen property related to a firearm, unlawful duplication, interception of communications, and criminal trespass, along with several misdemeanor offenses.
A judge is scheduled to sentence Kamnik on July 8.
Prosecutors said Kamnik used law enforcement and Commonwealth databases for personal purposes and created explicit material using artificial intelligence tools.
Investigators said some of the activity occurred on Commonwealth-owned devices at a Montgomery County state police barracks.
According to the investigation, Kamnik secretly filmed and photographed multiple individuals, including coworkers, and entered a women’s locker room at a state police facility to take images.
Authorities said evidence recovered from Kamnik’s cellphone and an external hard drive showed he accessed a secure law enforcement database, known as JNET, to obtain hundreds of images in violation of usage policies.
Investigators also recovered an unlawfully recorded video of a Montgomery County magisterial district judge that had been altered for inappropriate purposes, prosecutors said.
During a separate search of Kamnik’s vehicle in January 2025, authorities found a stolen .22 caliber firearm, leading to an additional charge.
Attorney General Dave Sunday said the defendant admitted to the full scope of conduct outlined in the charges.
“These crimes stain the great work being done by law enforcement every day in communities across the Commonwealth,” Sunday said.
The case was investigated by the Pennsylvania State Police, including its Internal Affairs Division, in coordination with the Attorney General’s Office.
Kamnik has been suspended without pay.
The case is being prosecuted by Senior Deputy Attorney General James Price and Deputy Attorney General Kimberly Moraski.
