"It is a sad fact of life that some murders go unsolved and that sometimes killers get away. However, nowadays new scientific techniques such as genetic finger printing offer a way of tracing the killers". 1987 Murder Unsolved - Weston-super-Mare. On the day she died-March 28,1987-she had left her blue-Datsun car in Worlebury Hill Road, near the entrance to the woods, and gone for a stroll with her white west Highland terrier Bilbow and brown mongrel Cindy. Police think the 66-year-old was probably returning to her car when the killer struck. Two people reported hearing a scream in the woods at 12.20pm that Saturday and Mrs Fleet's body was found 20 minutes later by a friend,Sylvia Lewis,who lived in Worle, and who had been alerted by the barking of the dogs. She had been beaten, stabbed and strangled. She saw her lying motionless and ran to a nearby house for help. David Davies andhis wife Hazel went with her into the woods and found her dead. But thge work of the police was hampered by the lack of an obvious motive -the widow had not been robbed and there was no indication of sexual assault. In the weeks and months that followed, 120 police officers interviewed more than 5,000 people and took hundreds of statements. But the bulk of their inquiries centred on trying to find two youths seen running away from the woods about half an hour after the killing. A man was also seen running along nearby Ashley Drive. One of the youths was described as aged bewteen 15 and 18, and 5ft 5in tall with dark trousers and a white ski-jacket with red and blue trim. The other was aged aboiut 16 and was also wearing a ski-jacket but with red and grey or dark blue squares. Six weeks after the murder, police released a photofit of a teenager seen chatting to Mrs Fleet in the woods two days before she died. Witnesses suggested that the pair knew each other and were talking quite openly He bore a strong resemblance to one of the youths seen fleeing from the woods shortly after the killing. As the passing months turned to years, many people in Weston believed the killer would never be found, but police continued to work away doggedly on the case. In 1997, on the 10th anniversary of the - murder, detectives revealed they were using new DNA tests to try to solve the case. They were examining clothes, blood, fingerprints and other evidence found at the scene. Originally, these had not yielded any clues, but, as DNA techniques became more sophisticated, the exhibits were subjected to repeated tests in the hope that they would provide the necessary breakthrough. Then, in 2000, in another effort to get the public to provide the vital information which could lead to the murderer, the case was featured on a TV Crimestoppers Special. At the time, detectives had been using the latest forensic techniques in their hunt and were hoping the computer-enhanced images - which had digitally 'aged' the youth who was seen talking to Mrs Fleet days before she died - might jog people's memories. Forensic scientists from the charity National Missing Persons Helpline had been working on the original photofit picture of 1987 and used new techniques to come up with what he might look like today. The Avon and Somerset force was one of the first in the country to use the technique to try and catch a criminal. , Officers, who believed Mrs Fleet knew the youth, asked people to look at the two pictures and to ring in if they recognised him. But they said that there was no indication that the man - who would now be in his 30s - was still living in the Weston area. A police spokesman said: 'The person seen talking to Mrs Fleet may or may not be her murderer. If people think they are that person seen speaking to her it is in their own interest to speak to us and give us their version of events. „ . , 'He was seen a number of times talking to her and we are very surprised we have not established his identity. We still believe there are people in Weston with information who have not yet come forward. We know it is not always easy People may have been struggling with their consciences and we hope this photograph will help.' The programme resulted in a new witness coming forward. He told detectives that he often saw Mrs Fleet talking to a youth who played with her dogs when she walked them in the woods. This squared with information taken from other people shortly after the killing. But despite a £7,000 reward on offer for information leading to conviction, no one has yet been able to give the police the lead they need to make an arrest. A man from Montpelier in Bristol was taken into custody five years ago in connection with the murder but was released from police bail without charge. Since then the trail has gone cold. 1987 The brutal murder of Helen Fleet The brutal murder of Helen Fleet has left a lasting legacy in Weston-super-Mare.
