Alyssa Bustamante—the 18-year-old Missouri girl who, at 15, confessed to murdering a 9-year-old neighbor and bragged about "killing people" on MySpace—has been sentenced to life in prison.

As Alyssa Bustamante's cache of "Jackass stunt" videos resurface on YouTube, Missouri's penal system finds itself at its wits' end trying to accommodate a rare beast: the violent female juvenile offender.

Alyssa Bustamante's MySpace, Facebook, and YouTube profiles are eerie in that "teen who engages in self-injurious behavior and bullshits about being tough" way. Except, when she lists "killing people" as a hobby? Police say that part was true.
