Victims ... David Miller, 24 and Hannah Witheridge, 23.

She did everything she could to convince her it was a bad idea because she was “out of my mind” with worry when the trip was first booked.

Tragically, her mother’s worst fears were realised.

It was on that trip in September 2014 on the party island of Koh Tao that the 23-year-old from Norfolk in the UK was brutally killed alongside another British backpacker, David Miller, 24.

They had only been in the country for days before they were murdered. Two men have been sentenced to death over her murder but are appealing their convictions on the basis of claims they were tortured into confessing.

They also claim evidence used to convict them was tampered with.

The details of the crime were chilling. The trial of the accused, Zaw Lin and Wai Phyo, heard details of Ms Witheridge being struck on the head with a hoe and raped. She and Mr Miller then were beaten to death so they couldn’t identify their attackers.

Their bodies were found semi-naked on the beach with obvious wounds.

Ms Witheridge’s death is now the subject of an inquest at Norwich Coroner’s Court. A statement from her mother revealed the family’s anxiety over the trip — and how she only made the decision to go at the last minute, reported The Sun.

“The family had always been against Hannah going on the trip and tried to persuade her out of it. None of the family was happy with her going there, but she had made her mind up.”

The original plan had been to go to Australia or Europe. To make her mother feel better, Ms Witheridge promised to Skype her every day.

“I was out of my mind when she did all this. But I relaxed when she got to the small island of Koh Tao because I knew she was just swimming and sunbathing,” reported the UK Daily Telegraph.

Then came the day no parent ever wants to experience. It was confirmation of her worst fears and that a mother’s intuition was right.

“September 16 was the day which changed our lives forever. My husband burst into my kitchen and collapsed crying and sobbing.

“It was like a bad dream — but my dreams were never like this.”

Ms Witheridge and Mr Miller had only just met. He had been backpacking across Asia and Australia before spending time on Koh Tao.

CCTV footage shows the two leaving a bar together just hours before their battered bodies were discovered.

The final photo of the pair looking happy and carefree, the couple appear to be with a large group of friends, enjoying their evening with drinks at a bar called Choppers.

Ms Witheridge’s family flew to Thiland to be told what happened and bring their “beautiful and fun loving” daughter home.

The facts of the case were excruciating to learn and “too much to bear”.

The statement included a touching tribute.

“There wasn’t a bad bone in her body. She achieved so much and had so much more ahead of her. Our family is broken and will never be the same again. It will never make any sense. The fact that she is not here, affects us every day.”

The inquest heard from a British Home Office pathologist, Dr Nat Cary, who detailed the injuries that killed Ms Witheridge were consistent with the blade of a hoe. It was likely she was struck multiple times and would have died quickly.

There were also signs of sexual assault and dragging.

Norfolk coroner Jacqueline Lake recorded a conclusion that Ms Witheridge had been unlawfully killed, reported the Daily Gazette.

But it appears the families of the victims are satisfied justice has been served.

Mr Miller’s family from Channel Islands said after the trial that they accepted the verdict.

Michael Miller — the brother of David — said “justice” had been served.

“He (David) was hacked down from behind, dragged into the sea and left to die. That will live with us forever. What happened to Hannah Witheridge is unspeakable,” he said.

“David always stood up for justice and justice is what has been delivered today,” he added, endorsing the work of the Thai police and the reliability of the forensic evidence.

And Ms Witheridge’s father — when asked for his view at the inquest — had this to say.

“I think it’s exactly how it happened, or unfolded.”
