A serious autopsy could well indicate the true cause of this latest death on the island of Ko Tao but here the police will do everything not to damage tourism as always. I don't think you can panic and call it the island of death for this series of deaths knowing that before the Covid, Ko Tao was visited annually by up to 3 million tourists. The island is also known as a dangerous island due to extreme sports and its natural configuration.
However, specified that this island is part of Chumphong which does not even have a good reputation from its inhabitants against tourists, several have died simply walking in the city late at night, attacked to steal what they possessed.
It is evident in Thailand in general it is also dangerous to go to isolated places alone or in pairs, there are many cases of unsolved murders in isolated places and not only on Ko Tao.
That Thailand is dangerous for tourists is evident, both for the traffic and for believing that the Thai smile welcomes you and you are not in danger.
