The police on these islands are inbred straw chewing bumpkins and one cannot hope for or expect western style of investigations or sample taking to occur.
As usual, all will be swept under the carpet asap and no soiling of thailands reputation as a safe and wondrous tourist destination will be allowed to take place.
Parents will weep, friends will wail, facebook pages will be inundated with meaningless grief,sombre candlelit vigils will be held, and armchair investigators will speculate, but the thai penchant for obfuscation, denial and deceipt will, as always, triumph in the end.
