A 23-year-old man was convicted on Wednesday, April 23, 2025, of possessing more than 100 images and videos depicting child sexual abuse material.

Mark Anthony McKay Jr., of Trenton Road, Middletown Township, was found guilty of possession of child pornography and criminal use of a communication facility following a waiver trial before President Judge Raymond F. McHugh.

McHugh deferred sentencing until June 25. 

This investigation began in March 2022 after Bucks County Detectives received a cybertip report from the National Center for Missing & Exploited Children (NCMEC), alleging a Dropbox user uploaded multiple videos and images depicting child pornography to the Dropbox server.

Officials with Dropbox provided detectives with the name of Mark McKay as the user who uploaded the images and provided his email address. Detectives reviewed the videos and confirmed that they were child sexual abuse material.

Through the investigation of the cybertip report and the Dropbox user’s IP address, McKay was developed as a suspect.

Detectives obtained a search warrant for the Dropbox account, which was in Mark McKay's name, and observed 102 files, all which contained child sexual abuse material. The videos and images from the original cybertip report were also located in the Dropbox account.

In July 2022, a search warrant was served at McKay’s home in the 800 block of Trenton Road, Middletown Township, where numerous electronic devices were seized, including a computer and McKay’s cellphone. Child sexual abuse material was also located on his cellphone.

The investigation found that McKay previously worked as an educational aide.

This investigation was conducted by Middletown Township Police Department, led by Detective Kevin Platenecky, the Bucks County District Attorney's Office, led by former Bucks County Detective David Coyne, and Homeland Security Investigations.

Deputy District Attorney Brittney Kern prosecuted the case.
