A 51-year-old man is behind bars after Maryland State Police said they found graphic child sexual exploitation material inside his Harford County home.

Troopers arrested Bel Air resident Matthew McMahon this week after they uncovered photos and video of child pornography during a months-long probe, authorities announced.

Specifically, McMahon was charged with 10 counts of possession of child pornography.

According to investigators, a trooper assigned to the Harford County Child Advocacy Center launched the case in September 2025, after developing information about the “possession and viewing of child pornography.”

McMahon was ultimately identified as the suspect who was found with illicit photos and videos of underage vidtims.

Troopers with the Maryland State Police Child Exploitation Unit, deputies from the Harford County Child Advocacy Center, members of the Maryland Internet Crimes Against Children Task Force, and Homeland Security Investigations served a search warrant at his Bel Air home on Tuesday, Dec. 2.

Police said McMahon was arrested on scene without incident. He was taken to the Harford County Detention Center, where he is being held without bond.
