In spite of claims of having a difficult childhood, bouts with depression and an addiction to pornography, a Howland teen is going to federal prison for more than five years after being convicted of child pornography charges.

David Hafely appeared before a judge in U.S. District Court on Friday where he was sentenced to a term of 97 months in prison, 37 months longer than the 60 months suggested by his attorney in a sentencing memorandum.

The 19-year-old former Howland High School student pleaded guilty earlier to charges of possession of child pornography, as well as receiving and transporting depictions of minors engaged in sexually explicit conduct.

Authorities say the pornographic images and videos found on Hafely's Kindle Fire tablet did not depict local children.

However, investigators say they traced the pictures and videos back to 21 victims.

As part of his sentence, Hafely has been ordered to make $42,000 in restitution to those victims.

When Hafely completes his prison term, he'll be placed on probation for ten years.
