LAWYERS filed an appeal yesterday against the conviction of two Myanmar workers sentenced to death for the 2014 murder of two British backpackers on Koh Tao, in another twist in a case mired in controversy and dispute.

The bodies of backpackers Hannah Witheridge and David Miller were found on a beach on Tao Island in September 2014. Police said Witheridge, 23, had been raped and bludgeoned to death and Miller, 24, suffered blows to his head.

A court sentenced migrant workers Zaw Lin and Win Zaw Htun to death after convicting them of the crime on December 24, 2014.

The 198-page appeal says the DNA evidence used in the case was inadmissible and had not been collected, tested, analysed or reported in accordance with internationally accepted standards, representatives of the two men said in a statement yesterday.

The appeal also says the questioning and charging of the migrant workers was unlawful because it was done without lawyers or trusted persons present, according to the statement.

Confessions, which the two later retracted, were extracted through torture or abuse, it said.

Police have denied mishandling the evidence or that confessions were extracted under duress.

Ruling expected next year

The mothers of the two Myanmar men accompanied the lawyers to court yesterday after visiting their sons on death row in a prison near Bangkok at the weekend, the statement said.

“We have submitted this to the Appeal Court so they can understand more, so they can see the importance on how a death |sentence decision needs to be |perfectly clear,” Nakhon Chompuchat, the defence team’s head lawyer said.

“We don’t have new evidence, we are basing this on evidence that was presented earlier,” he said.

The court would likely rule on the appeal in 2017, he said.

Police drew widespread domestic and international criticism for their handling of the case and the evidence.

Protests erupted in neighbouring Myanmar after the verdict, with many people there believing the two workers were scapegoats.
