A Virginia man was convicted earlier this week in the death of a 2-year-old who died during a 2011 exorcism. Eder Guzman-Rodriguez beat his daughter Jocelyn to death in an attempt to rid her of the demon he believed was inside her. Police summoned to the scene encountered several people holding Bibles outside the home, where Guzman-Rodriguez stated that he had also become possessed by a "bad spirit" when he punched and choked Jocelyn to death. The girl was found on a bed, wrapped in a blanket surrounded by Bibles. 
Exorcism is the alleged expelling of Satan or lesser demons. In reality, however, it's just people yelling and screaming.
