the families of the dead women must seek the assistance of their Embassy there,join hands together to solve what had happened.Why on earth will they not allow the bodies to be back home and instead would like to cremate there if there is no mystery? I have read before,there was also a tourist who was raped and killed in another resort in Phuket, that was last year?

u got it right, actually that is the first thing the thai authorities must do.Investigate the guest house owner and the surrounding circumstances before her death.
