A rock flying right into your windshield could change your life forever in a split second. Many incidents are accidents, but imagine if it was a deliberate act. Five teens from Michigan are accused of throwing six-pound rocks off an overpass. Now they are in shackles and their families are in a state of shock. The prank, called "dinging," killed 32-year-old Kenneth White. The teens pled not guilty to second degree murder charges at their arraignment.
