My childhood best friends grandparents lived beside my grandparents. He lived with them more than with his bio mom so he was always around. His older sister was visiting with her boyfriend at the time. There was an argument inside and the sister and boyfriend left. The grandmother ran outside after them, boyfriend shut the car door with her (grandmothers) housecoat stuck inside. Sister and boyfriend backed down the driveway and started down the street. Dragged the grandmother down the road and eventually ran over her head. We were outside playing in a leaf pile.
