The last moments of murdered British tourists Hannah Witheridge and David Miller on the Thai island of Koh Tao. The surveillance footage, released by a hotel nearby Sairee beach where the two bodies were found, separately shows Witheridge in pink top and white skirt, and Miller in a grey-blue t-shirt, walking back and forth between their hotel and a beach bar between the hours of 7pm to 1:46 am.
The bodies of the two 24-year-olds, both suffering head wounds, were found on the beach the following morning, sparking a manhunt to find the killer on the island.
Thai police have said they still have no prime suspects, and are looking for more evidence. They have said that the suspects are of Asian origin and that they are now waiting on DNA results.
A cash reward of £4,000 is being offered for any information that might help the investigation.
