(Delmarva Now) -- An Accomack County man was sentenced to 15 years in prison Tuesday in U.S. District Court in Norfolk after he pleaded guilty in January to a child pornography charge.
The sentence is the mandatory minimum.
John Martin Bowen, 56, of Melfa, was taken into custody in October and was indicted in November on nine charges involving child pornography.
When federal law enforcement officers executed a search warrant at Bowen's residence on Oct. 18, 2016, they seized several electronic devices on which they found "a staggeringly large collection of child pornography including many extremely disturbing images and videos," with some files dating back as far as 2006, according to a position with respect to sentencing document filed in court by the prosecution.
One of Bowen's laptop computers contained more than 700,000 images of child pornography and another contained more than 1 million images, according to the document.
Additionally, officers found a handcrafted, child-size doll in the same room with several of the electronic devices, suggesting Bowen "was not a mere passive viewer of child pornography," the document said.
The remaining charges were dismissed after Bowen agreed to plead guilty to one charge of receiving images of minors engaging in sexually explicit conduct.
He will be on supervised release for the remainder of his life once he completes his prison term, according to the sentence handed down by Judge Robert G. Doumar.
Bowen was described in one court document filed by the defense as "a caring son and dedicated member of the United States Navy" who had had a difficult childhood and who suffered from depression. He served 14 years in the Navy before being honorably discharged.
He worked from 2003 to 2016 as a shipping manager at a Cheriton agribusiness.
Bowen was required to register as a sex offender after a 2001 conviction on charges of aggravated sexual battery and taking indecent liberties with a minor.
