COLUMBIA — A former Columbia man was arrested Wednesday morning on suspicion of possessing and promoting child pornography over the Internet, according to a news release from the Mid-Missouri Internet Crimes Task Force.
The man identified as Nathan C. Eyberg, 29, was arrested at his parents' home in Jefferson City on suspicion of two counts of possession and one count of promoting child pornography, the release stated. The Mid-Missouri Internet Crimes Task Force news release originally cited a different spelling of the suspect's last name.
The task force began investigating Eyberg in early October after obtaining information that child pornography was being distributed out of a Columbia residence using an Internet file-sharing program, the release stated.
“We are constantly looking for child porn,” Andy Anderson, task force coordinator, said. “A police officer traced evidence that child porn was being shared over the Internet, and we obtained a court-ordered search warrant for the residence. We obtained several computers, one with a lot.”
The task force recovered several thousand pornographic files containing both photographs and video, which, along with interviews, allowed them to establish probable cause to arrest Eyberg, Anderson said. The files contained images depicting the molestation of children estimated to be as young as 3 years old, according to the release.
In a previous Missourian report, Anderson outlined the basic procedures used to link suspected persons to child pornography possession and distribution on the Internet. Programs such as LimeWire and BearShare are commonly used to create, “peer to peer networks,” which allow members to share media over the Web. If child pornography is being shared, investigators trace the Internet Protocol, or IP address, to find the location of the computer sharing the illegal files and serve a warrant.
Anderson said he could not elaborate on the specific tactics the task force used to gather evidence while investigating Eyberg.
