A Belleville, Ill. man arrested as part of Attorney General Lisa Madigan's crackdown on child pornography last year will spend more than a dozen years in federal prison for his crimes.

Garold Lee Semelka, 62, pleaded guilty in June to receiving and possessing child pornography. His computer contained more than 600 images or videos of minors engaging in sexually explicit activity.

Ill. Attorney General Lisa Madigan says a year-long effort to target the top 25 consumers of child pornography in Illinois has been a success.

Two Belleville men - 61-year-old Garold Lee Semelka and Mike G. Telkamp, 48, were the 25th and 26th men arrested under Operation Glass House, the anti-child pornography initiative Madigan launched in August 2010.
