Edward Mate, 78, of south suburban Riverdale is charged with aggravated child pornography.

The Cook County Sheriff's Office says it seized more than 1,000 graphic and sexually violent images involving children, including infants. The sheriff says a website tipped authorities after finding graphic images being exchanged in one of its chat rooms.

The Cook County sheriff says those images were then traced to Mate's computer address.
