June 26, 2010. A Pennsylvania state trooper witnesses a car speeding and crashing into trees. Stopping to help, he finds that the driver, Michael Ballard, is alive - and drenched in blood. When asked what happened, the man answers, "I just killed everybody." Not far from the accident, police make a gruesome discovery. In the home of Michael's ex-girlfriend, Denise Mehri, they find four bodies that had been stabbed repeatedly with a knife.
