DNA doubt over evidence in two backpackers’ deaths

Forensic samples taken from a weapon allegedly used to kill two British backpackers in Thailand do not match the two men on trial for the killing, a court has heard.

Hannah Witheridge, 23, from Norfolk, and David Miller, 24, from Jersey, were found dead on the island of Koh Tao last September.

Burmese migrants Zaw Lin and Wai Phyo are on trial for murder after denying their involvement.
