A 76-year-old Ruskin man has been sentenced to seven years and three months in federal prison after admitting he distributed, received, and possessed child sexual abuse material through an encrypted messaging platform. Michael Paul Linnan pleaded guilty in Tampa federal court in April and was formally sentenced on Wednesday by a federal judge to the 87-month term, along with a lifetime of supervised release conditions tied to his conviction.
According to the U.S. Department of Justice, federal prosecutors revealed that Linnan used an encrypted messaging platform to distribute and receive more than 100 images and videos of child sexual abuse material. Investigators also found that he stored hundreds of explicit videos on his phone and had transferred images to online cloud storage. As part of the sentence, U.S. District Judge Mary S. Scriven ordered Linnan to forfeit the cellphone used to commit the offenses.
Federal Charges Followed an FBI Tampa Investigation
The case against Linnan was built following an investigation by the Federal Bureau of Investigation's Tampa Field Office, with Assistant U.S. Attorney Muriel Moore prosecuting the matter, per the Justice Department's announcement. Interim U.S. Attorney Gregory W. Kehoe, who has led the Middle District of Florida since his March 2025 appointment by Attorney General Pamela Bondi, announced the final sentencing outcome. Kehoe previously spent more than two decades as a federal prosecutor and once advised the Iraqi Special Tribunal, the department notes.
Linnan's conviction was secured under Project Safe Childhood, a nationwide Department of Justice initiative launched in May 2006 to pool federal, state, and local law enforcement resources against child sexual exploitation. The initiative focuses on identifying offenders, prosecuting perpetrators, and rescuing child victims, according to the department's announcement, and the Middle District of Florida has historically been one of the country's most active jurisdictions for these prosecutions, having pursued more than 1,500 defendants under the program, per Hanlon Law. Many of those federal cases originate from cyber tips routed through the National Center for Missing & Exploited Children, the same firm notes.
Statutory Minimums Leave Little Room for Leniency
Under 18 U.S.C. § 2252A, receiving or distributing child sexual abuse material carries a mandatory minimum of five years in federal prison and a maximum of 20 years for a first offense, according to the Spodek Law Group. Federal convictions of this kind also carry mandatory supervised release terms and lifetime sex offender registration, the firm notes, meaning Linnan's 87-month sentence sits well above the statutory floor but leaves him subject to registration requirements for the rest of his life.
Judge Scriven, who presided over the sentencing, was appointed to the federal bench in 2008 by President George W. Bush after serving as a federal magistrate judge, according to the Federal Bar Association. She was the first African American woman appointed as a federal judge in Florida, the association notes. The U.S. Attorney's Office for the Middle District of Florida, which serves more than 11.5 million residents across 35 counties, is the second most populous federal judicial district in the country and maintains its headquarters in Tampa alongside four regional branch offices.
Part of a Broader Pattern in Hillsborough County
Linnan's sentencing follows a separate case just two months earlier in the same community. In June, Hillsborough County Sheriff's Office detectives raided a Ruskin home on 9th Street Northeast after tracing online child exploitation material, seizing digital devices in a case that began with a social media cyber tip and ended in a clash with detectives. That case and Linnan's are separate matters, but both point to how digital trails, from encrypted apps to cloud storage accounts, continue to drive both local and federal law enforcement action in the Tampa Bay area.
The Middle District of Florida has brought a string of similar prosecutions in recent months, including cases against a former Southern Nights club owner sentenced to 14 years in Orlando, a Tampa man sentenced to 15 years for AI-generated child sexual abuse material, and a Clermont man who admitted his role in an online exploitation ring. Federal officials have not indicated whether Linnan's case is connected to any of those separate prosecutions.
