LOS ANGELES (Reuters) - A Missouri woman who prosecutors say used a fake MySpace persona to "torment, harass, humiliate and embarrass" a 13-year-old girl who committed suicide was indicted on Thursday on federal charges. Lori Drew, accused of participating in a hoax on 13-year-old Megan Meier that led her to believe she was chatting with a 16-year-old boy, was indicted on conspiracy charges by a U.S. District Court jury in Los Angeles. Meier had what she thought was an online friendship with the fictional boy, "Josh Evans."
