The defence have until today to wrap up their case but chief lawyer Nakhon Chomphupat said they had experienced problems convincing witnesses to testify as some feared retribution. A verdict is due to be delivered in October.
Andy Hall, foreign affairs advisor for the Migrant Workers Rights Network, tweeted to say that judges asked the defence at the end of yesterday’s trial if their witnesses testimony would be be completed by today.
‘The judge will rule on the length of trial extension tomorrow and the judges, prosecution and defence lawyers will then agree on mutual dates.’
Burmese migrants Zaw Lin and Wai Phyo are accused of killing former Victoria College student Mr Miller (24) and Miss Witheridge (23), from Norfolk, on the Thai island of Koh Tao last September.
They face the death penalty if found guilty.
Defence lawyers claim their clients are being used as scapegoats but prosecutors say they have concrete evidence linking the pair to the crime.
‘There’s a problem, our informers lack courage to stand as witnesses because some of them still work on Koh Tao.’
Meanwhile, the family of Miss Witheridge have returned to court for the final days of her alleged killers’ trial.
In a brief statement the family said they were there to represent their ‘beautiful girl’.
‘Our world changed forever on 15 September 2014,’ they said.
‘Words cannot begin to explain the journey we have endured, a journey that has no end.’
‘We hope that the reporting of the case offers both Hannah and David their dignity and we ask that we are afforded our privacy to digest the case and the evidence being presented.
‘This story bears no happy ending; their lives were ended brutally that night without sense or reason.’
It is understood that Mr Miller’s family have not returned to Thailand.
The defendants deny charges of murder, rape and robbery.
