New details are emerging about the teenager who killed a teacher and a student at her school. Social media accounts believed to be linked to Natalie "Samantha" Rupnow suggest a fascination with previous school shooters. In an online document written by Rupnow, the troubled teen says she hates society and is "glad to be different."
