An investigation revealed that former Taiwanese decathlete Ku Chin-shui, who was not aboard the flight, had given two bleach bottles containing gasoline to his nephew to transport, which exploded when exposed wires attached to a motorcycle battery in the same overhead bin as the gasoline sparked after being jostled during the landing. Ku was convicted in 2002 and sentenced to seven and a half years in prison, but a later trial upon his appeal found him not guilty on 27 December 2004.
