WARMINSTER, Pa. – A man in Bucks County who possessed hundreds of files containing child sexual abuse material, including files he created of an underage neighbor, learned his sentence Wednesday. 

Christopher L. O’Neill, 47, will serve seven to 20 years in state prison for possessing and distributing child pornography, some of which was generated using AI tools, the Bucks County District Attorney’s Office said in a news release.

The DA’s office said he received an additional, consecutive term of one year of probation.

Common Pleas Judge Stephen A. Corr formally designated O’Neill as a sexually violent predator after the prosecution and defense presented expert clinical testimony, the DA’s office said.

The DA’s office said the designation requires O’Neill to register for life with the Pennsylvania State Police. 

O’Neill pleaded guilty earlier this year to two counts of possessing child pornography and one count of criminal use of a communication facility, according to the DA’s office.

In a second related case, he pleaded guilty to theft by unlawful taking and receiving stolen property, the DA’s office said.

During the sentencing, the victim’s parents said O’Neill has shown no remorse for his crimes, according to the news release. The victim’s father described him as a “predator cornered” who attempted to excuse his actions by blaming substance abuse, the DA’s office said.

The DA’s office said it began investigating June 10, 2025, after it received multiple CyberTips. Investigators determined that between September 26, 2024, and May 7, 2025, O’Neill saved, shared, and uploaded a substantial quantity of child sexual abuse material, according to the DA’s office.

Law enforcement recovered 694 illicit photos and videos from Google Photos and two images from PicsArt, according to the DA’s office.

The DA’s office said forensic analysis confirmed that some of the illicit files involving a 15-year-old neighbor were generated using artificial intelligence. 

O’Neill entered a neighbor’s Warminster home and stole various items, including a pair of the child’s underwear, a day after authorities served a search warrant to seize O’Neill’s electronic devices, the DA’s office said.
