PORTLAND, Maine — A Berwick man was sentenced Tuesday in U.S. District Court to seven years in prison for possession of child pornography.

Jack B. Moore, 52, also was sentenced by U.S. District Judge D. Brock Hornby to eight years of supervised released.

In addition to prison time, the judge ordered Moore to pay more than $22,000 to three victims for one year of counseling each, according to the U.S attorney’s office, which prosecuted the case.

Moore pleaded guilty in April.

He had been held without bail since his arrest in December 2011 in North Carolina.

The investigation that led to Moore’s arrest began in 2008 when two different FBI agents monitoring the Internet for known images and videos of child pornography traced downloads to Moore’s IP address, according to the prosecution version of events to which he pleaded guilty.

On Oct. 15, 2008, the FBI in Maine seized a computer, camera, printer, four compact discs, 104 floppy disks, an address book, printouts of pictures of child pornography and nonpornographic photos of minor girls, according to the court document.

The National Center for Missing and Exploited Children found in Moore’s collection 2,000 images and six videos of child pornography from 33 known series, including 201 images of known child pornography on the floppy disks, according to the prosecution version of the crime.

Moore left Maine and went to live with a relative in North Carolina, according to the sentencing memorandum submitted by J. Hilary Billings, the federal public defender who represented Moore. When he was arrested there, investigators found more child pronography on his computer.

“He told the arresting officers that he started with adult pornography, and the age of the people in the images he viewed became younger and younger as time went by,” the attorney wrote.

Moore faced up to 10 years in federal prison and fine of up to $250,000.
