According to court documents, in May 2020, agents from Homeland Security Investigations (HSI) began investigating a lead from the Clay County Sheriff’s Office (CCSO) about the uploading and sharing of files depicting the sexual abuse of children from a residence in Jacksonville Heights. CCSO reported that an agent with the North Dakota Bureau of Criminal Investigation had also commenced an investigation into an upload and distribution of files of child sexual abuse material from the same residence around the same time period. HSI learned that the Jacksonville Sheriff’s Office had also been investigating the sharing of depictions of the sexual abuse of children from the same residence in July 2020, and the Leon County Sheriff’s Office had begun an investigation of the upload of files depicting sexual abuse from the residence in September 2020. HSI, working with CCSO and the St. Johns County Sheriff’s Office, executed a federal search warrant at the residence on December 3, 2020. However, HSI discovered that Sills had recently moved from the residence in Jacksonville Heights to an apartment in the Ortega area. HSI determined that the same file-sharing program that had been used at Sills’s former residence was being used at Sills’s new address. Agents located internet activity consistent with the upload of depictions of child sex abuse.

“Every time child pornography is shared, it victimizes a child again,” said HSI Jacksonville Assistant Special Agent in Charge K.
