WASHINGTON — A Fairfax County man, whose computers in his basement bedroom contained more than 600,000 images of child pornography, has been convicted.

On Wednesday, a circuit court jury found Adrantes Bruzual, of Herndon guilty, and sentenced him to 12 years in prison with a $4,000 fine.

In February 2014, a Fairfax County detective who was monitoring a file sharing network for people trading child pornography, discovered an Internet Protocol Address, which geo-located within Fairfax County.

After confirming the files contained child pornography, detective Nick Boffi traced the physical address of the IP to the home on Missouri Avenue, in Herndon, that Bruzual shared with his parents and sisters.

While executing a search warrant, Boffi located two computer towers and two monitors in Bruzual’s basement bedroom.

In an initial interview, police say Bruzual admitted he was the only person who used those computers.

A forensic search found several hard drives, containing over 600,00 images of child pornography.

Bruzual was charged with 20 counts of child pornography, and later indicted.

In trial, Bruzual testified other people used the computers found in his room, and he had no idea the pornographic images were on the computers.
