Darrin Cates pleaded guilty on October 23, 2015.

According to court records, on January 9, 2015, law enforcement authorities executed a search warrant at Cates’s residence and seized computer equipment. A forensic examination revealed about 550 images and 276 videos of child pornography depicting two to 11-year-old children. Cates admitted that he possessed large quantities of child pornography and that he was interested in eight to 12-year-old girls.

In imposing sentence, Judge John Woodcock noted that the images were “egregious,” “disturbing” and “abhorrent” and said that Cates “committed a crime that touches upon a societal nerve,” and that it was “profoundly troubling” that Cates collected such “truly sick images.”

The investigation was conducted by the Maine State Police Computer Crimes Unit and U.S. Immigration and Customs Enforcement’s Homeland Security Investigations.
