Parkville Man, Former Baltimore County Correctional Officer Pleads Guilty to Production of Child Pornography

Thomas Michael Mannion, Jr.

Thomas Michael Mannion, Jr., a 46-year-old former Baltimore County correctional officer from Parkville, Maryland, pleaded guilty on Monday in federal court to two counts of production of child pornography, while admitting to engaging in sexually explicit conduct with two minor victims.

Last May, Baltimore County Police were called a town home in Parkville after a neighbor witnessed a minor breaking in through a back door.

When the neighbor entered the home to investigate, he found Mannion, who had been renting a basement apartment in the home, in bed naked with a male minor who was also unclothed.

When police arrived, officers located the boy, who was 13-years-old at the time, in the basement bedroom area.

The investigation revealed that Mannion had met the boy a few months before on a social media platform and brought him to his apartment, where they engaged in sexually explicit conduct.

Mannion took photos and videos of the boy during the sexual encounter and distributed the explicit images to others.

A forensic analysis of Mannion’s cellphone revealed nearly 30 images and two videos depicting the boy engaged in sexually explicit activity with Mannion last year.

Mannion also communicated with a second minor — a 14-year-old male — through the social media platform and admitted that he went to the child’s home where he engaged in sexual activity with him and took photographs and videos documenting the sexual encounters.

As with the first minor, Mannion distributed pornographic images of the boy to multiple users of the social media platform.  The forensic analysis of Mannion’s cellphone recovered 18 images and two videos documenting the sexual activity with the minor.

According to the plea agreement, Mannion attempted to meet with several other minors with whom he communicated on social media, even after the minors advised him of their ages.

He also discussed his sexual interest in other children that he knew or with whom he had contact during sexually explicit chats on the social media platform.  In addition, a review of Mannion’s laptop computer revealed multiple images of child pornography.

Along with previously working as a Baltimore County correctional officer, Mannion worked previously as a deputy sheriff at Bexar County Sheriff’s Office in San Antonio, Texas, according to his Facebook account profile.

United States Attorney Robert K. Hur, FBI Special Agent in Charge Jennifer Boone, Homeland Security Investigations, the Baltimore County Police Department, and the Baltimore County State’s Attorney’s Office worked in collaboration on the case against Mannion who had originally been charged with second degree rape and a number of other sexual assault charges, along with the distribution of child pornography charges.

Mannion faces 15-30 years in federal prison for each of the two counts of production of child pornography, followed by up to lifetime supervised release.
