The family of Hannah Witheridge have released a statement as the trial draws to a close.
Hannah, 23, from Hemsby, in Norfolk, was killed alongside David Miller 24, on the island of Koh Tao last year.
Two Burmese workers accused of the killings deny the charges, claiming they were tortured for their confessions.
"Our family have returned to Koh Samui for the closing days of trial. As a family we are here to represent our beautiful girl.
Our world changed forever on 15th September 2014. 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.
Please remember, above all, that Hannah and David were both real people, they were loved by their families and all those that were privileged enough to know them. This story bares no happy ending; their lives were ended brutally that night without sense or reason."
