TAVERNIER, Fla. – The Florida Department of Law Enforcement (FDLE) has arrested Mark Christopher Harris, 63, of Tavernier, on 12 counts of possession of child sexual abuse material (CSAM), six counts of possession of computer‑generated CSAM, and two counts of possession of material depicting the sexual abuse of animals. The arrest is part of FDLE’s statewide initiative to identify and apprehend offenders who target children and share files depicting child sexual abuse.

In June 2025, agents received a cybertip from the National Center for Missing and Exploited Children (NCMEC), submitted by Microsoft, reporting that an unknown user conducted a reverse image search that returned images depicting the sexual abuse of children. Agents traced the associated IP address to Harris.

In August 2025, agents received a second NCMEC cybertip from Google regarding an account containing images of unclothed children. Further investigation determined the account also belonged to Harris.

On Dec. 2, 2025, agents conducted a residential search warrant at Harris’ home and seized multiple electronic devices for forensic review. One device contained a large quantity of CSAM, including computer‑generated images and images depicting bestiality.

FDLE’s Special Operations Team, Homeland Security Investigations (HSI) and the Monroe County Sheriff’s Office assisted with the search warrant.

On Jan. 15, 2026, Harris turned himself in to the Monroe County Sheriff’s Office and was booked into the Monroe County Jail.

The Office of the State Attorney, 16th Judicial Circuit, is prosecuting the case.

The investigation remains active.
