The Department of Justice announced the results of Operation Grayskull, a joint effort with the FBI that successfully dismantled four dark web sites containing child sexual abuse material and resulted in convictions carrying more than 300 years in combined prison sentences.
Operation Results
The investigation led to the conviction of 18 offenders across multiple states. Thomas Peter Katsampes, 52, of Eagan, Minnesota, received the most recent sentence yesterday: 250 months in prison plus lifetime supervised release, along with $23,000 in restitution.
Katsampes pleaded guilty in February to conspiracy charges related to advertising and distributing child pornography. Court documents show he joined a dark web site in 2022, distributed illegal material, and eventually became a staff member responsible for moderating content and advising users.
Key Convictions in Southern District of Florida
Eight individuals were convicted for running the primary site targeted by the operation:
William Michael Spearman (Madison, Alabama) received a life sentence and was ordered to pay $123,400 in restitution for engaging in a child exploitation enterprise.
Joseph Addison Martin (Tahuya, Washington) was sentenced to 42 years in prison with $174,500 in restitution, also for engaging in a child exploitation enterprise.
Keith David McIntosh (Grand Rapids, Michigan) received 55 years in prison for conspiracy charges, enhanced due to a prior conviction.
Other sentences ranged from approximately 21 to 28 years, with restitution orders totaling hundreds of thousands of dollars.
Additional Prosecutions Nationwide
Nine more individuals were convicted in other federal districts:
- Charles Hand (Maryland): 14 years
- Clay Trimble (Arkansas): 18 years
- Samuel Hicks (Indiana): 16 years
- Richard Smith (Texas): 14 years
- Michael Ibarra (Washington): 12 years
- David Craig (Texas): 9 years
- Robert Rella (Virginia): 5 years, 8 months
- Patrick Harrison (Michigan): 5 years, 10 months
- Thomas Gailus (Oklahoma): sentencing pending
International Impact
The operation extended beyond U.S. borders, resulting in arrests in the United Kingdom, Netherlands, Italy, Germany, Estonia, Belgium, and South Africa. Two other individuals in the United States died before charges could be filed.
Site Operations
According to court documents, the dismantled websites were among the most serious on the dark web, containing sections specifically targeting infants and toddlers, as well as violent content. Site leaders maintained sophisticated operations including staff meetings, user promotion systems, and detailed advice on avoiding law enforcement detection.
Investigation Details
The FBI’s Child Exploitation Operational Unit and Miami Field Office led the investigation, with assistance from FBI offices in eight states. The Justice Department’s Child Exploitation and Obscenity Section coordinated prosecutions.
Quotes from Officials:
“Today’s announcement sends a clear warning to those who exploit and abuse children: you will not find safe haven, even on the dark web,” said Acting Assistant Attorney General Matthew R. Galeotti.
FBI Director Kash Patel called it “one of the most significant strikes ever made against online child exploitation networks.”
The operation was conducted under Project Safe Childhood, a Department of Justice initiative launched in 2006 to combat child sexual exploitation and abuse.
