A full DNA profile, which police believe belongs to the killer, was created from crime scene evidence in 2008 but "a missing piece of the jigsaw has yet to be traced". But ultimately, the programme drills down to a closer examination of the case against Stone. It is, clearly, far from convinced. When I came out of the appeals court the media were there,” says Stone, “and they shouted out ‘Michael’. I shouted out, right at the top of my voice ‘I’m an innocent man’ to reach the media. And if you look at my face [in still photographs] it looks like I’m going psychopathic or something – but I’m actually shouting ‘I’m an innocent man’.

A 47-year-old woman, also from Coulsdon, has also been arrested on suspicion of assisting an offender. All five remain in custody. The answer is ‘probably not’ but it does do a very fine job in highlighting the key elements of such a grisly crime. Formal identification has not yet taken place, however, the family of a 54-year-old woman reported missing from Upstreet on Wednesday 23 August are aware. The death is being treated as suspicious and on 24 August a man in his 20s from Margate was arrested on suspicion of murder.” The detonation caused the building to collapse and a further 21 people were injured but the people responsible have never been found. The full list has been revealed by Kent Police and, despite many fresh appeals as well as more modern forensic techniques, the killers of these 40 people have never been caught.The impression of the child was still there, as if he had been softly taken out,” Elizabeth recalled. The impact on the people involved in those first moments is both harrowing and clearly emotional all these years later. Michael Stone has been behind bars since he was first arrested in 1997 Miss Knell's body was left in her bedsit by the murderer, whereas Miss Pierce's was dumped on Romney Marsh. A Kent police spokesperson said the death was being treated as suspicious. He said: “Officers have attended a location near Minnis Bay, Birchington, where a woman was found deceased. Kent police was alerted by a member of the public shortly after 7pm on Friday 25 August and patrols are currently at the scene. Stone’s legal team travelled up to Durham – Bellfield is in the same jail as Stone – to get more information.

In just April this year, the parents of Wendy Knell asked the public for help to establish the identity of their daughter's killer.Anyone with information should call 999, quoting reference number 23-1922.

Her car, a silver Suzuki, was found parked in the village of Saint Nicholas-at-Wade, where she is believed to have walked from. It was known as the Great Crime of 1860. On June 29, 1860, an unknown assailant murdered 3-year-old Francis Savile Kent in a brutal fashion. The Kent family lived in the peaceful village of Road in Wiltshire. Their home, known as Road House Hill, was an elegant setting for the family of nine and their three servants.

The headless body of a teenager was discovered more than 10 years ago but no one has ever been charged with his murder. Two years later members of the Staff Band of the Royal Marines School of music were in their recreation room in Deal when a bomb went off. Despite numerous appeals for information and multiple arrests, police have never been able to make any significant progress, leaving his family desperate for answers. The only physical evidence connecting Constance to the crime was a missing nightdress — that Whicher believed Constance was wearing when she killed the child.Explains Stone’s barrister, Mark McDonald: “From that meeting, we got a lot more detail. We had the description by Bellfield, of what they were wearing, how he did it, who he hit first, how he murdered them, who he tied up, how he’d killed the dog. He said he knew the area very well.

Mr Dighton said: "I have still got hope that it will be done and dusted one day and they will catch who did it." Richard Leivers – the Kent Police officer who saw the dead bodies and carried Josie Russell from the copse when he noticed she was still alive – speaks of the profound impact it still has on him all these years later. “Nothing,” he reflects, “could prepare me for what I saw.”

A Brutal Murder At Road House Hill
