Datan was arrested in November at Los Angeles International Airport as he returned from the Philippines. Investigators found hundreds of sexually explicit images of boys in his digital camera.
A search of Datan's home in Normal Heights the next day turned up sexually explicit photos of child victims from prior trips to the Philippines and a large collection of pornographic images of children.
He was one of about a dozen men from around the nation charged under a law adopted in 2003 that included provisions increasing the penalties for those convicted of engaging in sex with minors overseas. The law also eased the burden of proof for prosecutors.
Immigration and Customs enforcement investigators focused on Datan because he was among about 130 people in San Diego and Imperial counties whose names appeared on a list of people who used credit cards to buy child pornography from a Belarus-based ring.
