In 2011, Stephanie Pistey, an 18-year old girl from Panama City, Florida, was found guilty of being an accessory to the murder of a 16-year-old boy named Jacob Hendershot. Investigators suspect that her involvement in the boy's death stemmed from the vampire cult that she belonged to.

"Since I was like 12, every fiber in my body, basically everything, I know this is going to be crazy, but I believe that I'm a vampire and part werewolf," the 18-year-old stated in a video interview with MSNBC.

At the time of her arrest, Pistey's Facebook profile listed "unworldly things" and "blood" among her main interests. She said that although she has drunk the blood of her fiancé and co-defendant William Chase, she did not drink the blood of the murder victim.
