A medical source said he suffered a fatal injury to the inferior vena cava, a large vein that carries the deoxygenated blood from the lower and middle body to the heart.

The condition in general is called Blunt abdominal trauma, or injury to abdominal organs.

This reportedly caused excessive bleeding and injury to the liver. The child died from Inferior vena cava (IVC) rupture.

Earlier on Monday, officials at the University Teaching Hospital of Kigali (CHUK), said one of the 17 people, who were admitted, including the driver and teacher, was in critical condition and needed surgery.

The New Times could not get official confirmation from the CHUK about the passing of Mugabo.
