An Elizabeth City man who had more than 16,000 images of child pornography in his possession has been sentenced to 10 years in federal prison.

Alan Sigfred Anderson, 57, was sentenced to the active prison term by U.S. Chief District Judge Terrence W. Boyle in Raleigh on Wednesday, according to U.S. Attorney Robert J. Higdon Jr. Anderson pleaded guilty to one count of possession of child pornography on Nov. 19.

Following his prison term, Anderson must serve a lifetime of supervised release, Higdon said.

According to Higdon, an investigation of a file sharing network identified Anderson’s internet protocol address as advertising child pornography files. The probe further found that files containing child pornography were downloaded directly from his IP address.

After identifying Anderson’s address in Elizabeth City, law enforcement officials obtained a warrant to search his home, Higdon said. Special agents with Homeland Security Investigations and Pasquotank sheriff’s deputies executed the search warrant on Feb. 28, 2018, seizing numerous electronic devices from Anderson’s home.

Anderson agreed to speak with investigators and admitted to downloading and storing child pornography, Higdon said. A forensic review of the devices seized from his home revealed more than 16,000 images and videos of child pornography.

Higdon said the investigation of Anderson was conducted through the Project Safe Childhood initiative and also involved members of the Cary Police Department.
