An Surprise, Arizona man, Kelly James Morrow, who admitted molesting four young boys in China and documenting the abuse with hundreds of photographs and videos has been sentenced to 25 years in federal prison.

Kelly James Morrow, 49, who has a U.S. residence in Surprise, but been living in China prior to his arrest last June, was sentenced Monday by U.S. District Judge S. James Otero. The case resulted from a probe by U.S. Immigration and Customs Enforcement’s (ICE) Homeland Security Investigations (HSI) and the National Center for Missing and Exploited Children, which provided the initial lead that led to the investigation.

Morrow pleaded guilty in April to two charges – sexual exploitation of children outside the United States and possession of child pornography.

“This defendant is a sexual predator who not only abused young boys – he also documented their physical and mental abuse by taking thousands of pictures of his victims,” said United States Attorney Eileen M. Decker. “Just as Morrow’s photographs continued to victimize boys that he molested, his massive collection of child pornography victimized every one of the hundreds of child abuse victims depicted in those images.”

Morrow was arrested in June 2015, about a week after arriving at Los Angeles International Airport on a flight from Singapore. A search of his computer equipment and digital media revealed a collection of more than 60,000 images and videos depicting child pornography. In addition to the images Morrow produced in China while working on golf course projects, Morrow admitted in a plea agreement filed in court that he took a nude photograph of a young boy in Lincoln, Nebraska, in late 2014.
