(COLORADOAN) — A 13-year-old boy extorted into sending naked pictures of himself to someone he thought was a female classmate.

A Fort Collins seventh-grader having sexually explicit video chats with a man nearly twice her age.

A 10-year-old having phone sex with a Loveland man who thought she was a 13-year-old.

The cases highlight the dangers kids face when they go online: They don’t actually know who they’re talking to, and they don’t know where the pictures they send may end up. Parents across Larimer County are struggling to keep up with their kids as they use and sometimes abuse Facebook, mobile phones, video chats and the Internet, in some cases with lifelong repercussions.

As part of an exclusive news investigation, WND’s Chelsea Schilling located dozens of child-porn images posted by pedophiles and predators who trade thousands of pornographic photos on Facebook. The four-part series included: 1) “Kids raped, sodomized on Facebook Pages,” 2) “Can Facebook’s child porn explosion be stopped?,” 3) “Investing in Facebook? You don’t have clean hands” and 4) “Facebook kid porn: Reaction hot and heavy.”
