Erin Caffey was 16 when she decided her family had to die. On March 1, 2008, in Texas, her ex-boyfriend Charlie Wilkinson, 19, and his friend Charles Waid, 20, entered her home with guns and a katana while she waited outside in a car.
They killed the mother, nearly decapitating her in her bedroom. Her 13-year-old brother was shot in the face, and her 8-year-old brother was stabbed to death. They set the house on fire with everyone inside. Terry, the father, was shot five times and managed to crawl 300 meters through flames to get help.
The motive, according to prosecutors: her parents had forbidden her from continuing to see Wilkinson. Two days after the family confrontation, the plan was already underway. Erin received two life sentences plus 25 years. She will not be eligible for parole until she is 59 years old.
