Cause of death

Traumatic rupture of the thoracic aorta

AI-generated summary

A 16-year-old male died from traumatic rupture of the thoracic aorta following a motor vehicle collision. The vehicle left the road and struck trees after the driver applied brakes while on gravel, causing severe lateral deceleration forces. Although the deceased's seatbelt failed during the collision (due to a design flaw where two anchor points shared the same bolt, creating a scissor effect under lateral loading), forensic evidence confirmed the aortic rupture occurred before seatbelt failure. The fatal injury resulted from severe deceleration forces rather than from the seatbelt failure. The coroner identified a potential design defect in the Daewoo Espero rear seatbelt anchoring system that could be corrected with a spacer between anchor points, and referred findings to the vehicle distributor.
