Quite so, some were very mysterious like :
"Frenchman Dimitri Povse, 29, was found hanged in a bungalow on the island on New Year's Day 2015 and his death was ruled as suicide despite his hands being tied behind his back.
Associate Professor Charnkanit Krittiya Suriyamanee, a criminologist and lecturer at the faculty of social science and humanities of Mahidol University, said he doubted the suicide theory citing some irrelevant evidences, according to Chiangrai Times.
He said that the victim had been drunk to the extent that he was unable to control himself, he would not have been able to tie himself up so tightly that he died of suffocation."
