He's dead. Karma or fate... But when you live as carelessly as this man lived, it's not at all surprising. Maybe even deserved. Given his purported history, I suspect the list is quite long as to possible suspects.
Not everyone from Malaysia... there are day trippers from every country with a land boarder crossing, and they (as is everyone else is) are counted as "tourist"... stat-padding.
"projected" 25 million by years end... those are 2014 numbers... still a long way to go to 40 million (pre-covid, 2019). Counting all the Malaysian day-trippers is just stat-padding.
Love the cheap charlies who think they can get a good haircut for 100-150 baht... A good cut, from someone who can swing a pair of scissors (and not just an electric clipper) is going to cost you 300-500 baht, minimum.
Easy to get visas (or visa free entry) and blending in with the hoards of tourist... Sure, THA has always been a great hideout for criminals. Neither new nor news.
