BANGOR, Maine — A Corinth man was sentenced to four years in prison for possession of child pornography during an appearance Thursday before Judge George Z. Singal at U.S. District Court.

David Livingston Brown, 41, also was ordered to undergo eight years of supervised release after completing his sentence, U.S. Attorney Thomas E. Delahanty II said in a news release.

Brown pleaded guilty to the charge on July 28 of last year.

According to court records, Brown emailed a video containing child pornography to an undercover federal agent in April 2013. On July 18, 2013, a search warrant was executed at Brown’s home in Corinth.

Brown admitted to sending and receiving images of child pornography by email and collecting hundreds of images and videos of child pornography over several years.

A forensic examination of computers and computer storage devices seized from Brown’s home turned up hundreds of images and videos of child pornography.

The joint investigation that led the to conviction was conducted by the FBI and the Maine State Police Computer Crimes Unit.

The case was brought as part of Project Safe Childhood, a nationwide initiative launched in May 2006 by the U.S. Department of Justice to combat the growing epidemic of child sexual exploitation and abuse.

Led by U.S. attorneys’ offices and the Justice Department’s Child Exploitation and Obscenity Section, Project Safe Childhood marshals federal, state and local resources to better locate, apprehend and prosecute individuals who exploit children via the Internet, as well as to identify and rescue victims.
