A LaGrange Park man who is a former part-time employee of the Lyons Township High School radio and television stations will plead guilty to possessing and transporting child pornography next month, according to court documents.

Late last month, U.S. District Court Judge Amy St. Eve ordered that Nathan Arger’s change of plea hearing be held on June 19 and any plea agreement or plea declaration be delivered to her by June 18.

Arger, 32, was arrested in September of 2011 at his home by the FBI, which reported seizing hundreds of images and a dozen videos depicting children exposing their genitalia and engaged in sexual acts with adults.

Agents also reported that Arger himself was pictured with two different prepubescent girls, one of whom was nude from the waist down.

Arger was placed on unpaid leave from his part-time, non-faculty job at LTHS when his arrest was announced. He is not suspected of engaging in any illegal activity involving Lyons Township High School students or any of the school’s technology equipment.

He has been under home confinement after posting $100,000 bond shortly after his arrest. Arger was indicted in October 2011 and ordered to undergo mental health counseling in advance of his trial. At the time he pleaded not guilty to the charges against him.

Now it appears a trial won’t be necessary if Arger changes his plea, as expected, on June 19.
