In June 2000, a young woman from Wales set off on a round-the-world trip in search of adventure, excitement and discovery. Only two months later her trip would come to an abrupt and violent end while she stayed at a backpackers hostel in the Chiang Mai province of Thailand.
Now, twelve years on, her mother has embarked on a similar journey, this time in search of answers, determined to find those responsible, and finally bring justice to Kirsty.
News of Kirsty's death was broadcast accross the world and the Thai police explored various lines of investigation in the search for her killer. There was a string of wittnesses and the guest house owner was initially charged with rape and murder before the evidence against him was declared not to be credible.
It was at this point that the Jones family contacted their local police force which would prompt a Welsh investigation that has lasted well over a decade.
The involvement of Dyfed Powys Police would soon result in a major breakthrough as her clothes and belongings were brought back to Wales for analysis and DNA was found which would suggest her killer was from the Chiang Mai area. Both Dyfed Powys Police and the Thai Police were now able to refocus their search. But again the years went by and the inquiry seemed to go nowhere.
Then, early this year, the team from Dyfed Powys Police went to Thailand once more to meet the new investigator in charge of Kirsty's case.
Wales This Week travelled with Sue Jones when she returned to Thailand, a journey which was far from easy but which she felt was vital in the continued search for her daughter's killer
Speculation and theories about Kirsty's death have been rife in the Far East ever since it happened but with Sue's appeal for information and the offer of a ten thousand pound reward, there's renewed hope of a breakthrough in a case which has led to such anguish for twelve years.
Wales This Week: Justice for Kirsty is on tonight (4th September) at 7.30 on ITV 1 Wales
