2. An Autopsy Case of a Stunt Man Who Jumped into Seawater Riding a Motorcycle: A Case Report

We report a rare case of the death of a stunt man who jumped into the sea driving a motorcycle on location for a TV drama. A special ramp had been constructed for the jump. The stunt man and a passenger drove up the ramp at a speed of 60–70 km/h and jumped into the sea from a height of about five metres. Both men swam up, but the driver fell unconscious at the surface. He was sent to hospital, but did not recover. The autopsy revealed a deep laceration of the right axilla with complete rupture of the axillary artery, bone fractures of the right ribs and the right pelvis, and a small laceration of the upper lobe of the right lung. Other visceral organs were not injured. We finally judged that his cause of death was exsanguination due to rupture of the right axillary artery on the basis of the presence of a small amount of blood inside the heart and ischemic organs. All injuries were probably inflicted by a collision with the motorcycle upon reaching the water surface; the axillary injury might be due to the left handlebar piercing into the part.
