A Port Neches man has been sentenced to 25 year in federal prison on child pornography charges. 33-year old Christopher Dale Harrison was found to be in possession of child pornography during a search of his home in April of last year. During the search, agents located and seized an external hard drive and a cell phone from the house and a camera that he had recently purchased at a local pawn shop. All items contained images of child pornography. Harrison pleaded guilty to the charges in November and was sentenced yesterday.
