Nathaniel McAlpine, a 48-year-old St. Petersburg resident and convicted sex offender, has been sentenced to 11 years in federal prison for attempting to coerce and entice a minor into sexual activity. The disturbing crime occurred while McAlpine was on supervised release for possession of child pornography. In September 2025, a jury found him guilty, and U.S. District Judge Brian Miller handed down the sentence. McAlpine’s online conversations, which took place with someone he believed to be the mother of a child, revealed his attempts to persuade her to engage in sexual activity with the child.
However, investigators discovered that the person McAlpine was communicating with was actually an online scammer, not a real mother. The case was investigated by Homeland Security Investigations and prosecuted by Assistant United States Attorney Courtney Derry as part of Project Safe Childhood, a nationwide initiative to combat child sexual exploitation and abuse.
McAlpine’s sentence reflects the seriousness of his crimes and the need to protect children from predators like him. The case highlights the importance of Project Safe Childhood, which brings together federal, state, and local resources to locate, apprehend, and prosecute individuals who sexually exploit children.
The Department of Justice launched Project Safe Childhood in May 2006 to address the growing epidemic of child sexual exploitation and abuse. The initiative has led to the prosecution of numerous individuals who have attempted to exploit and harm children. McAlpine’s case serves as a reminder of the dangers that exist online and the need for continued vigilance in protecting children from sexual predators.
