In July 2011, Florida, 17-year-old Tyler Hadley killed his parents with hammer, after a few hours, he invited 40-60 people to his party through Facebook at home in the night. They played, smoked and drank when the bodies of Tyler’s parents were still in the bedroom. Finally Tyler was charged with second-degree murder. Nobody could understand why he killed his parents, it is really just because they won’t allow him holding a party? Hadley had left high school and hit a child while driving his father’s car in 2010.
