PORTLAND, Ore. (AP) – A Portland man who educated children was sentenced to 15 years in federal prison for producing child pornography by sexually exploiting young children online.

The Oregonian/OregonLive reports 34-year-old Juan Carlos Ramon had taught elementary school in California and was running after-school programs at North Gresham Elementary School when arrested in November 2017.

Ramon pretended he was a young girl online and began communicating with two girls, ages 6 and 8, via an internet application known as musical.ly. On the app, he engaged in a sexually-explicit game of “Simon Says,” asking the girls to send him nude photos.

A relative of the girls discovered the images and informed authorities.

Ramon admitted to federal investigators he used his iPhone and computer to send, receive and store child pornography. He said he had been requesting pornographic images from girls for several years using the website “Omegle.”

Ramon in court apologized to his victims, family and friends.
