ALLIANCE, Neb. (AP) — A former Alliance hospital executive has been sentenced to three years in federal prison for possessing child pornography.

A judge sentenced 65-year-old James Parks on Tuesday and ordered him to serve five years of supervised release and register as a sex offender. He pleaded guilty in August to the charge in a deal with prosecutors.

The Nebraska State Patrol says the 2013 investigation began after a report from Box Butte General Hospital officials raised questions about information found on Parks’ work computer.

Authorities say a search of his email account showed conversations of a sexual nature about young girls between Parks and another man. Authorities say the account showed evidence the two men had exchanged videos and photos that depicted children sexually.
