Jacksonville Child Sex Offender Sentenced To 15 Years For Receiving Child Sexual Abuse Materials Over The Internet And Ordered To Pay $45,000 In Restitution To Child Victims

Jacksonville, Florida – Senior United States District Judge Timothy J. Corrigan has sentenced Alexander James Koby (40, Jacksonville) to 15 years in federal prison for receiving child sexual abuse materials (CSAM) over the internet. Koby was also ordered to serve a 15-year term of supervised release and pay $45,000 in restitution to child victims. Koby pleaded guilty on August 15, 2025. Koby has been in federal custody since September 2024 when he was transported from state prison 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 of possessing CSAM. After serving his federal prison sentence and being released in August 2019, Koby began serving a 25-year term of supervised release while living in Jacksonville.

On December 7, 2022, a search of Koby’s residence revealed that he possessed a computer, a cellphone, and an external hard drive in violation of the terms of his supervision, and 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 further 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 devices seized from Koby’s residence revealed that they contained a total of 103 videos and 2,311 photos depicting the sadistic sexual abuse of young children. Koby had downloaded these contraband materials using the internet from March 11 through December 7, 2022.

“This predator’s repeated conviction for seeking out and downloading hundreds of videos and thousands of photos depicting the sadistic sexual abuse of children—to ‘live dangerously’—is in defiance of the law, and at the expense of perpetuating the lifetime victimhood of innocent children,” said Homeland Security Investigations Jacksonville Assistant Special Agent in Charge Tim Hemker. “These images and videos are not just pictures, but evidence of heinous crimes against real children. Every time this vile material is viewed or shared, the suffering of these young victims is renewed. HSI and the INTERCEPT Task Force partners will stop at nothing to find these predators and hold them accountable to their crimes.”

This case was investigated by Homeland Security Investigations. It was 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.
