The families of Thailand murder victims Hannah Witheridge and David Miller have been invited to help secure death sentences for the suspects despite widespread doubts over whether police have caught the real killers. Justice officials said the grieving parents can team up with prosecutors to file joint murder charges against two Burmese migrant workers accused of the brutal killings of the  backpackers on a Thai beach. The quirk of Thai law means murder victims’ families can hire lawyers and investigators who could turn up additional evidence or testimony.
