Steven Dennis Mack, Receiving Child Sexual Abuse Material, Florida 2025

Tampa, FL – In a shocking case, U.S. Air Force Major Steven Dennis Mack (40, Tampa) has been sentenced to five years in federal prison, followed by a lifetime of supervised release, for receiving child sexual abuse material (CSAM).

The sentencing was handed down by U.S. District Judge Steven D. Merryday, who also ordered Mack to pay $42,500 in restitution; $40,000 in fines; and required him to register as a sex offender.

Mack entered a guilty plea on March 6, 2025, after an investigation by the United States Air Force Office of Special Investigations Detachment 340 at MacDill Air Force Base and the Tampa Police Department.

According to court documents, Mack sent an image of CSAM from his personal email address to an individual with an email address that geo-located to the Philippines. Law enforcement obtained a search warrant for Mack’s email address and found hundreds of emails exchanged with the Philippines user in which they discussed engaging in sexual activities with minors.

Law enforcement executed a search warrant at Mack’s Tampa residence, where they seized a cellphone and laptop computer. A search of the laptop showed that Mack searched terms consistent with CSAM and accessed pornographic content. A search of the cellphone revealed that it contained 64 images of CSAM.

Further investigation revealed that Mack had viewed most of those images in Tampa in June and December 2023. This disturbing case highlights the growing epidemic of child sexual exploitation and abuse.

This case was brought as part of Project Safe Childhood, a nationwide initiative launched in May 2006 to combat child sexual exploitation and abuse. Assistant United States Attorney Ross Roberts prosecuted the case.

The investigation and prosecution of child sex offenders is a top priority for law enforcement agencies nationwide. Cases like Mack’s serve as a reminder of the importance of vigilance and cooperation in the fight against child exploitation.
