Part 3 of 3. So after hearing about the case of Hannah and David it is time to hear about some of the cases which have also given Koh Tao the reputation that it has today. Hear the story of a body found in a drain pipe. Numerous deaths at sea, 2 tourists found hung. A 50ft fall where there was no broken bones. A questionable bike accident and a death where even the police cannot agree on the cause. But the underlying story to all of them, they were all closed without a satisfactory answer.
