Today, the Justice Department shared details of Operation Grayskull, a joint initiative with the FBI that successfully dismantled four dark web sites involved in child sexual abuse material (CSAM). The operation has led to 18 convictions, including that of Thomas Peter Katsampes from Minnesota. Katsampes was sentenced to over 20 years in prison and ordered to pay restitution.
“Yesterday’s sentencing reaffirms our steadfast commitment to protecting our children,” said U.S. Attorney Hayden P. O’Byrne for the Southern District of Florida. “Thomas Peter Katsampes and his co-conspirators ran some of the darkweb’s most heinous networks, enabling horrific crimes against innocent victims.”
The operation has been lauded as a significant blow against online child exploitation networks. “We’ve not only dismantled dangerous platforms on the dark web,” noted FBI Director Kash Patel, “but we’ve also brought key perpetrators to justice.”
Several individuals were convicted in the Southern District of Florida, including Selwyn David Rosenstein from Boynton Beach, Florida; Matthew Branden Garrel from Raleigh, North Carolina; and others. Their sentences ranged from several years to life imprisonment.
Operation Grayskull resulted in arrests beyond the United States, including in countries such as the United Kingdom and Germany. Former Assistant U.S. Attorney Gregory Schiller and other officials coordinated these efforts under Project Safe Childhood, an initiative aimed at combating child sexual exploitation.
