In 2002, 91-year-old Edwin Hiles was murdered in his Oxfordshire home and the way police tracked down his killer changed forensic investigations forever and led them straight to the killer
Frail 91-year-old Edwin Hiles was brutally murdered in his Oxfordshire home by a former local slaughterman who cut his phone line so he couldn’t call for help.
Paul Weedon, 24 – who worked in the ‘gut room’ of Mutchmeats’ slaughterhouse in Witney, Oxfordshire – stabbed the pensioner in the throat in 2002 after trying to rob the widower when he refused to give him money for rent.
Mr Hiles’ body was found in the front downstairs living room of his semi-detached home by a neighbour who had called in to see him. But there was no sign of the killer.
Mr Hiles was known in his community for his small-scale money lending to those in hard times and detectives immediately linked his murder to his generosity and that he may have had cash at his house
What followed changed British forensic science forever. In order to catch the killer, investigators pioneered a breakthrough technique known as “fibre-taping” for the first time in the UK – linking the victim’s body directly to bloodstained clothes Weedon had stashed in a nearby woodland close to where he was living in Chipping Norton.
Rather than just gathering loose fibres to see if the two people interacted, investigators used a complete, grid-indexed tape on both the killer’s clothing and Mr Hiles’ body to reconstruct their positions during the attack.
During the trial in 2003, Weedon had changed his story multiple times, even claiming to have seen drug dealers kill the elderly widow, according to the Oxford Mail. He also claimed he had been deliberately framed by an acquaintance who had had dealings with Mr Hiles.
But later on, he then said he stabbed Mr Hiles in the throat after the pensioner came at him with a kitchen knife to stop the robbery. In mitigation, Julian Baughan, defending, said: “This wasn’t pre-planned. It was intended possibly as an application for a loan which turned into a robbery which went wrong.”
The breakthrough forensic testing from 2003 will be shown and explained on the brand new documentary series UK Forensic Breakthroughs on the True Crime channel. Spanning across 10 episodes, each instalment will focus on its own murder case where scientific breakthroughs and microscopic evidence secured justice for grieving families.
Forensic scientist Jo Millington will give exclusive access to the experts behind the investigations, including the case of Edwin Hiles, which is set to air on September 27. Jo Millington has been a forensic scientist for over 30 years, even working behind the scenes on BBC’s Silent Witness.
Speaking of the new documentary, Jo Millington said UK Forensic Breakthroughs stands out from other crime shows and explained: “The first difference is that it puts forensic science at the heart of the show, which normally sits on the periphery in the shadow.
“Over a 10 part series, we’re using the programme to kind of assure a spotlight on forensic science. And more importantly, the scientists that do forensic science, every single day.”
Jo explained how forensic evidence isn’t just about fingerprints and bloodstains. Speaking to the Mirror, she said: “Forensic science is based on the principle that every contact leaves a trace and that’s exactly what people do when they commit a crime. Every interaction, every step has the potential to leave material in the crime scene or take it away.
“The challenge sometimes is finding the evidence in the first place, but once forensic scientists do find it then they can start to interpret it and put it into the context of an investigation.
“The evaluation of the science is really important. For example, finding my DNA in a place where I live or work is unlikely to unlock a case, but if investigators find my fingerprint in the blood of the person that has been injured, then that is like a timestamp.
“It tells you I was there when the person was bleeding – that contextual evaluation is vital – and in that particular example, I would have questions to answer.”
As well as shining a light on the forensic science work, Jo aims to tackle one common misconception about her job. She added: “The thing about forensic science is it’s mostly a process – things need to happen in a particular order in line with a particular method and the results need to be checked and double checked by people who are trained and competent.
“The chain between the evidence that is collected from a crime scene and the scientific findings that are presented to the court, and the jury, needs to be water-tight. That level of diligence and checks takes a longtime.”
