A Jacksonville man with a prior conviction for child sexual abuse materials (CSAM) has pleaded guilty to new charges of receiving such illicit content over the internet. Alexander James Koby, 40, faces a significant federal prison sentence, potentially ranging from 15 to 40 years, along with a life term of supervised release, U.S. Attorney Gregory W. Kehoe announced on Wednesday, August 20, 2025.
Background and Prior Conviction
Koby’s plea marks his second federal conviction related to child sexual abuse materials. In 2014, he was found guilty in federal court for possessing CSAM. After serving his federal sentence, Koby was released in August 2019 and began a 25-year term of supervised release, a period during which he was expected to adhere to strict conditions.
He has been held in federal custody since September 2024. This transfer occurred after he was moved from state custody, where he was serving a sentence for failing to register as a sex offender.
Investigation and Confession
On December 7, 2022, law enforcement conducted a search of Koby’s Jacksonville residence. During the search, officers seized a computer, a cellphone, and an external hard disk drive, all suspected of containing illicit materials.
During an interview following the search, Koby admitted to using a specific internet browser to search for photos and videos depicting children being sexually abused. He also confessed to masturbating while viewing these materials. When asked about his continued engagement in such activities, Koby disturbingly stated that he derived a “high from living dangerously.”
Forensic Findings and Charges
A thorough forensic examination of the three seized devices yielded a substantial cache of illicit content. Investigators discovered a total of 103 videos and 2,311 photos depicting young children being sexually abused. These materials were downloaded and received by Koby via the internet between March and December 2022.
Koby’s sentencing hearing is scheduled for November 20, 2025. The case was investigated by Homeland Security Investigations and is being prosecuted by Assistant United States Attorney D. Rodney Brown.
The guilty plea of Alexander James Koby underscores the ongoing efforts by federal authorities to combat the proliferation of child sexual abuse materials. This case highlights the severe penalties associated with such crimes and the persistent vigilance required to protect children from exploitation.
