John Brennan Crutchley, better known as the  Vampire rapist, was a suspected serial killer who is believed to have murdered up to 30 women. Although never convicted for these crimes, one brave teenage girl was able to put him behind bars... but only after he raped her and drank half her blood. Then we get into the holiday spirit with the Christmas time killing spree of Ronald Gene Simmons. He killed 16 people in Arkansas - including his entire family.
