Just after school started in September 2011, Nathan Arger was busted by the FBI. Friday night, he is headed to prison after receiving a twelve and a half year sentence.
It is the finish of the case that outraged west suburban parents and Arger's neighbors, and disgusted most anyone who read the charges.
"It's just scary, it's a very unsettling, scary feeling," said Amy Wiginton.
Wiginton, whose family lived across the street from the child porn suspect, expressed a sentiment typical of reaction when the case broke in 2011.
Across the street in LaGrange Park lived a 34-year old man who had amassed a stunningly large collection of child pornography.
Arger was known in kiddie porn circles as "MrDizzle420" when the FBI traced sexual, sadistic images of young children to his computer.
Nearly 67,000 child porn pictures and almost 3,000 videos of children kept on his computer.
Arger lived in the basement of his father's house.
"What do you say about it? He made a mistake. He has a problem. And that's the way it is," said Daniel Arger, Nathan Arger's father.
According to FBI records obtained by the I-Team, Arger's computer files were titled: "Boys," "Documents," "Girls," and "Private."
During initial questioning Arger told federal agents the focus of his child porn collection are images of girls 5 to 10 years old; and that he kept images of young boys just to trade with other child porn fans.
During the investigation authorities say Arger worked part-time at Lyons Township High School, but that neither school equipment nor students were involved in his crimes.
For more than a decade one of the FBI's top initiatives has been to stop child exploitation and close down related organized sex rings.
They have arrested hundreds of people, but child pornography remains one of the fastest growing online businesses pegged at more than $3 billion in income to the purveyors of perversion.
