Alexander James Koby, a 40-year-old resident of Jacksonville, has pleaded guilty to receiving child sexual abuse materials (CSAM) over the internet. The announcement was made by United States Attorney Gregory W. Kehoe. Koby faces a mandatory minimum sentence of 15 years and could receive up to 40 years in federal prison, as well as a possible life term of supervised release. His sentencing is scheduled for November 20, 2025.
Koby has been in federal custody since September 2024 after being transferred from state custody, where he was serving time for failing to register as a sex offender. Court documents show that Koby was previously convicted in federal court in 2014 for possessing CSAM. After completing his sentence, he was released in August 2019 and began serving a 25-year supervised release term.
On December 7, 2022, authorities searched Koby’s residence and seized several electronic devices including a computer, cellphone, and an external hard disk drive. During an interview with investigators, Koby admitted using an internet browser to search for images and videos depicting the sexual abuse of children and said he masturbated while viewing them. When questioned about his continued actions, Koby stated that he gets a high from “living dangerously.”
A forensic review of the seized devices uncovered 103 videos and 2,311 photos showing young children being sexually abused. Investigators determined that Koby had downloaded these materials between March and December of 2022.
The investigation was conducted by Homeland Security Investigations and is being prosecuted by Assistant United States Attorney D. Rodney Brown.
"This case was investigated by Homeland Security Investigations," according to the press release.
The prosecution falls under Project Safe Childhood—a national initiative launched by the Department of Justice in 2006 to combat child sexual exploitation and abuse. The program brings together resources from various agencies at all levels to locate offenders who exploit children online and provide justice for victims.
