According to court documents, in April 2008, the Martin County Sheriff's Office (MCSO) began investigating the use of file sharing software to transport child pornography over the Internet. Law enforcement officers identified Duncan's computer as having numerous child pornography videos available for downloading over the Internet. The MCSO determined Duncan lived in Jacksonville and the Jacksonville Sheriff's Office (JSO) Vice Unit then continued the investigation.
On May 16, 2008, ICE special agents and the JSO Vice Unit executed a search warrant at Duncan's residence. After being advised of his constitutional rights, Duncan told law enforcement that he used file sharing software to share files and that child pornography would probably be found on his computer. Agents seized a desktop computer and numerous compact discs that revealed approximately 33 videos of child pornography. Some of the child pornography videos portrayed sadistic conduct involving children.
The arrest of Duncan was part of Operation Predator, a comprehensive ICE initiative aimed at those who prey on children, including human traffickers, international sex tourists, Internet pornographers, and foreign national predators whose crimes make them deportable.
Additional information about Operation Predator is available on the Web at www.ice.gov. ICE encourages the reporting of suspected child predators and any suspicious activity through its toll-free hotline at 1-866-DHS-2ICE. This hotline is staffed around the clock by investigators. Suspected child sexual exploitation or missing children may be reported to the National Center for Missing & Exploited Children, an Operation Predator partner, at 1-800-843-5678 or http://www.cybertipline.com.
