Abstract:
A 15-year-old male died of cardiac rupture due to blunt chest trauma from a traffic accident involving a low-speed scooter carrying 3 people and a head-on collision with a tree. The victim was sitting on the footrest of the scooter. It was concluded that the victim was compressed between the handlebar of the scooter and the other 2 passengers, causing cardiac ruptures via bidirectional compression and intravascular hydrostatic pressure. The victim may have served as a cushion for the other 2 passengers, who were not thrown from the scooter and sustained only minor injuries.
