A Herndon man who was found with more than 600,000 child pornography images on his computer will face jail time.

A Fairfax County circuit court jury last week  found Adrantes Bruzual, 34, of Herndon guilty, and sentenced him to 12 years in prison with a $4,000 fine, WTOP reports.

In February 2014, a Fairfax County Police detective who was monitoring a file sharing network for people trading child porn, discovered an Internet Protocol (IP) address within Fairfax County.

After confirming the files contained child pornography, detectives traced the address of the IP to a home on Missouri Avenue in Herndon.

Police executed a search warrant and took two computer towers and two monitors from Bruzual’s basement bedroom. A forensic search found several hard drives, containing over 600,00 images of child porn.

Bruzual was charged with, and later indicted on, 20 counts of child pornography. In his trial, Bruzual testified that other people used the computers found in his room. He said he had no idea the images were on the computers.
