(AP) — An April trial is scheduled for a 65-year-old former hospital executive in Alliance accused in a child pornography case.

James “Jim” Parks pleaded not guilty on Monday to seven felony counts of possession of child pornography. He is a former member of Alliance’s Police/Citizen Advisory Board.

The Nebraska State Patrol says a four-month-long 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 an email account of Parks 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.

His trial is set to begin April 28.
