Jacksonville Convicted Child Sex Offender Pleads Guilty To Receiving Child Sexual Abuse Materials Over The Internet

Jacksonville, Florida – United States Attorney Gregory W. Kehoe announces that Alexander James Koby (40, Jacksonville) has pleaded guilty to receiving child sexual abuse materials (CSAM) over the internet. Koby faces a minimum penalty of 15 years, up to 40 years, in federal prison and a potential life term of supervised release. His sentencing hearing is scheduled for November 20, 2025. Koby has been in federal custody since September 2024, after he was transported from state custody, where he was serving a sentence for failing to register as a sex offender.

According to court documents, in 2014, Koby was convicted in federal court for possessing CSAM. After serving his federal sentence and being released in August 2019, Koby began serving a 25-year term of supervised release.

On December 7, 2022, a search of Koby’s residence revealed that he possessed a computer, a cellphone, and an external hard disk drive. These items were seized. During an interview, Koby admitted that he used a particular internet browser to search for photos and videos depicting children being sexually abused and that he masturbated when viewing these materials. When asked why he would continue to do this, Koby stated that he gets a high from “living dangerously.” 

Forensic examination of the three seized devices revealed a total of 103 videos and 2,311 photos depicting young children being sexually abused. Koby had downloaded and received these materials using the internet from March through December 2022.

This case was investigated by Homeland Security Investigations. It is being prosecuted by Assistant United States Attorney D. Rodney Brown.

It is another case brought as part of Project Safe Childhood, a nationwide initiative launched in 2006 by the Department of Justice to combat the growing epidemic of child sexual exploitation and abuse. Led by the United States Attorneys' Offices and the Criminal Division's Child Exploitation and Obscenity Section, Project Safe Childhood marshals federal, state, and local resources to locate, apprehend, and prosecute individuals who sexually exploit children, and to identify, rescue, and seek justice for child victims.
