ROSEBURG, Ore. — A Roseburg man has been sentenced to 14 years and eight months in prison after pleading no contest to five counts of Encouraging Child Sexual Abuse in the First Degree in a case involving one of the largest collections of child sexual abuse material ever discovered in Oregon.
The Oregon Department of Justice announced that 56-year-old David Arthur Kelly was sentenced in Douglas County Circuit Court after investigators uncovered more than 740,000 files of child sexual abuse material (CSAM) on a hard drive at his residence.
According to authorities, the investigation began when members of the Southern Oregon Child Exploitation Team (SOCET) identified CSAM files being shared through a publicly accessible peer-to-peer file-sharing network. Between June 2023 and August 2024, investigators made 19 separate connections to Kelly’s computer and downloaded numerous illegal files.
The Oregon Department of Justice Internet Crimes Against Children (ICAC) Task Force assumed the investigation in October 2024, identified Kelly as the suspect, and executed search warrants at his Roseburg home.
Investigators discovered a one-terabyte hard drive containing more than 740,000 CSAM files, all of which were configured to be shared over the internet, according to prosecutors.
“This is 740,000 instances of a child being exploited and that exploitation being spread,” Oregon Attorney General Dan Rayfield said in a statement. “This man didn’t just possess this material; he made it available to anyone who wanted it. This sentence reflects the severity of those choices, and I commend the dedicated investigators at SOCET and our ICAC Task Force who did the painstaking work to bring this case to justice.”
Kelly entered his plea before Douglas County Circuit Court Judge Kathleen Johnson. During sentencing, Kelly told the court he had “made a mistake.” Judge Johnson rejected that characterization, citing the enormous volume of material involved and telling Kelly that his actions “were not a mistake” but rather “a series of repeated decisions to exploit children.”
Kelly was indicted by a Douglas County grand jury on Nov. 6, 2025, on 10 counts of Encouraging Child Sexual Abuse in the First Degree. As part of a stipulated agreement, he pleaded no contest to five counts and received a sentence of 176 months in state prison.
The case was prosecuted by Senior Assistant Attorney General Elijah Michalowski of the Oregon Department of Justice Criminal Justice Division, who was appointed as a special prosecutor by Douglas County District Attorney Richard Wesenberg.
