Lucas Michael Chansler is a 26-year-old sexual predator sentenced to 105 years in prison after pleading guilty to multiple counts of child pornography production. Over several years, he tricked roughly 350 teenage girls from 26 states into giving him explicit pictures of themselves by posing as a teen boy and befriending them online before threatening to distribute the photos on social media. He was eventually tracked down to his Jacksonville, Florida home when one victim reported his extortion attempts to the FBI and the The National Center for Missing and Exploited Children. While the Feds have been able to locate more than 100 of his underage victims, nearly 250 young women have yet to be identified. And that's where you come in.
