“Mr. Morris has a low chance of being a repeat offender because of his general maturity and the fact that he would likely respond to the requirements of probation,” Moon said moments before delivering a punishment.

The terms of the sentence include placement on the federal sex-offender registry and 20 years’ supervised probation upon release from prison. Moon will decide within 90 days the amount of restitution to be paid to the victims identified in the pictures and videos.

Defense attorney David L. Heilberg argued for the most lenient sentence possible and said the Internet sharing program could have delivered much of the pornographic material found on Morris’ computer without his knowledge.

“Looking at the big picture, this is the only thing in all his years that Mr. Morris has ever done wrong,” Heilberg said. “It’s serious, but so is [the mandatory minimum of] five years in prison.”

Federal prosecutor Nancy Healey countered that Morris had to have some knowledge of what was on his computer because much of the material came from people he met in live chat rooms. Plus, he admitted to investigators that he had a predilection for child pornography, she added.
