A Rocklin man pleaded guilty today in federal court in Sacramento to possession of child pornography.
According to the plea agreement filed in the case, law enforcement officers in September 2011 identified a computer at the home of Donald G. Callahan, 62, offering child pornography through an Internet file-sharing service. On Oct. 25, agents searched his home and seized his computer and several compact discs.
The computer contained approximately 898 image files and 536 video files showing the sexual exploitation of children, according to a federal Department of Justice news release. On the compact discs were an additional 16 video files.
Callahan is scheduled to be sentenced by U.S. District Judge Morrison C. England Jr. on Sept. 20.
The case is the result of an investigation by the Sacramento Internet Crimes Against Children Task Force, a federally and state-funded task force managed by the Sacramento County Sheriff's Department with agents from federal, state and local agencies. The Sacramento task force investigates online child exploitation crimes, including child pornography, enticement and sex trafficking.
