The Appeals Court has upheld the death penalty handed down by the lower court on two Burmese migrant workers for the murder of British backpackers David Miller and Hannah Witheridge on Koh Tao in 2014.
A legal adviser to the convicted men's families, migrant-rights activist Andy Hall, told the BBC that he and the pair's counsel "don't believe the court can say beyond reasonable doubt that Zaw Lin and Wai Phyo were responsible for the events which took place in September 2014".
David Miller's parents made a statement today to English broadcasting company ITV.
TWO Burmese men found guilty of murdering Islander David Miller and a woman from the United Kingdom have lost appeals against their convictions.
The appeal judges ruled that the evidence accumulated during the investigation "was up to standard" and that the DNA found at the scene matched that of the suspects.
They added "Zaw Lin and Wai Phyo will now have time in jail to reflect on their horrific crimes".
Miss Witheridge, a University of Essex student from Hemsby, and Mr Miller, a civil and structural engineering graduate, were found on a beach having been bludgeoned to death.
However the family hoped Thai authorities would show leniency in relation to the death sentence. Miss Witheridge was beaten with the same weapon and raped.
Both men appealed their convictions, claiming that the confessions made during questioning, which were later retracted, had been extracted through torture or abuse.
