A Salt Lake City man was ordered to spend almost 20 years in prison for possessing child pornography.

U.S. District Judge Dale Kimball sentenced William Seth Hooker on Tuesday to 235 months behind bars. Hooker had admitted he possessed depictions of children engaged in sexual activity.

Hooker, 47, has prior convictions for child sexual abuse, sexual exploitation of a minor and rape of a child for crimes that occurred in 1997. He currently is serving a 150-month federal sentence for a 2007 armed bank robbery.

Kimball ordered that 120 months of the pornography term run concurrently with the bank robbery sentence and 115 months run consecutively to it. In addition, he placed Hooker on 10 years of supervised release after he gets out of prison.
