Hope for John Cooper as DNA clears man jailed in 1987
Breakthrough in UK’s longest miscarriage of justice highlights power of new forensic science
A MAN jailed for a brutal murder 38 years ago has today walked free from court after the Court of Appeal quashed his conviction—offering renewed hope to others claiming wrongful imprisonment, including Pembrokeshire’s most notorious inmate, John Cooper.

Peter Sullivan, now 68, was convicted in 1987 of the rape and murder of 21-year-old barmaid Diane Sindall, who was attacked while walking home from work in Birkenhead. Despite maintaining his innocence throughout, Sullivan spent nearly four decades behind bars—until new forensic testing revealed DNA from an unknown man on preserved crime scene samples.
The Criminal Cases Review Commission (CCRC) referred the case back to the Court of Appeal last year, and today (May 13), judges ruled that the fresh evidence completely undermined the original conviction.
Sullivan’s case is now believed to be the longest-known miscarriage of justice involving a living prisoner in British legal history.
The ruling highlights the growing role that advances in DNA science are playing in overturning unsafe convictions. It also raises serious questions about other historic cases—including that of John Cooper, who is currently serving a whole-life sentence for the 1985 murders of Richard and Helen Thomas in Scoveston Park and the 1989 killings of Gwenda and Peter Dixon near Little Haven.
Cooper’s 2011 conviction relied heavily on DNA and forensic evidence—particularly fibres and trace DNA allegedly linking him to the crime scenes years after the murders occurred. Advances in forensic science were hailed at the time for cracking the cold cases, but serious questions have since been raised about the handling and interpretation of that evidence. Critics argue that crucial items were poorly stored, contaminated, or even cross-referenced between unrelated cases, with incomplete exhibit logs and inconsistencies in how samples were managed. There are also concerns that some forensic results were presented to the jury with greater certainty than the underlying science could justify, potentially prejudicing the verdict.
Cooper’s legal team submitted a detailed appeal dossier to the CCRC in 2023.
The case is now under formal review.
Concerns raised include missing or contaminated forensic samples, questionable police procedures, and the alleged mixing of evidence from unrelated cases.
One of the team supporting cooper in his fight to get his name cleared said: “If there was nothing in it, the case would have been rejected already.”
He added that the Peter Sullivan ruling shows how persistent investigation and modern science can uncover serious flaws in past prosecutions.
While Cooper remains behind bars, the momentum from today’s decision may shift public and legal focus back to the unresolved questions surrounding his case.

Man jailed after strangling partner and attacking police officer
A MILFORD HAVEN man who strangled his partner during a violent domestic assault before attacking a police officer has been jailed for two years.
Timothy John, aged 38, of Howarth Close, Milford Haven, appeared at Swansea Crown Court after admitting a series of offences arising from an incident in October.
The court heard that John had been arguing with his partner about his drug use when the situation escalated into violence. Prosecutor Craig Jones said the defendant grabbed the woman by the throat and held her in a chokehold for around ten seconds, leaving her struggling to breathe and fearing she would lose consciousness.
During the attack, John also punched and kicked the victim before smashing a glass bong over her head. At the time, the woman was still in her underwear and managed to flee the property and run into the street to seek help.
John also damaged the victim’s mobile phone by biting the screen, rendering it unusable.
Police attended the address the following day to take a statement from the victim and discovered John hiding in a bedroom. When officers attempted to detain him, he assaulted a female police officer, knocking her glasses to the floor, before escaping from the property.
The defendant handed himself in around 24 hours later.
John pleaded guilty to intentional strangulation, assault occasioning actual bodily harm, assaulting an emergency worker, criminal damage, and escaping from lawful custody. The court was told he has five previous convictions for six offences, although none for violence.
Defending, Dan Griffiths said John accepted the relationship was over and had been using cocaine at the time of the incident, which had made him paranoid, volatile and unpredictable.
He told the court that John had previously worked as a fisherman, roofer and welder, but had struggled with alcohol and substance misuse. Mr Griffiths added that a pre-sentence report highlighted a difficult upbringing and noted a lack of insight into his offending, with concerns that he attempted to minimise his behaviour.
The defence urged the court to consider a suspended sentence to allow John to work with probation services.
Sentencing, Judge Catherine Richards said the offence involved serious strangulation and a sustained assault on an intimate partner, leaving the victim frightened in her own home.
John was sentenced to two years’ imprisonment and made subject to a ten-year restraining order preventing any contact with his former partner.
Dyfed-Powys Police have been asked to provide a custody image of the defendant.

Police investigate suspicious disappearance of white-tailed eagle in mid Wales
Appeal launched after satellite tag is found cut from bird and dumped on remote moorland
POLICE and wildlife crime officers are investigating the suspicious disappearance of a satellite-tagged white-tailed eagle in mid Wales after its tracking device was found cut off and deliberately hidden.
Dyfed-Powys Police is working alongside the UK National Wildlife Crime Unit (NWCU) following the disappearance of the juvenile bird in the Newtown area.
Officers say the satellite tag and harness were recovered from remote moorland and show clear signs of having been removed from the bird using a sharp instrument, most likely a knife, before being concealed in an apparent attempt to dispose of the evidence.
Despite searches in the area, the body of the eagle has not yet been located.
Police are now appealing for information from anyone who may have been in the area at the time and witnessed suspicious activity.
Investigators are particularly keen to hear from people who were:
- At or around Gwgia Reservoir, Tregynon, between 11:00am and 1:00pm on Saturday (Sept 13)
- On access land near Bryn y Fawnog between midday and 3:00pm on the same day
All potential lines of enquiry are being pursued, including detailed forensic examination for DNA and fingerprints.
Police are working closely with the tag owners, the Roy Dennis Wildlife Foundation, and Forestry England to analyse tracking data and support the investigation.
The disappearance is being treated as a serious wildlife crime. The persecution of birds of prey remains a national policing priority, with species such as white-tailed eagles, golden eagles and hen harriers fully protected by law.
Satellite tags are widely used for conservation and research purposes, providing vital information about bird movements and survival. Each tag carries contact details so that any recovered device can be returned directly to researchers.
Members of the public who enjoy the countryside are urged to remain vigilant and report any suspicious activity involving birds of prey or their habitats.
Anyone with information is asked to contact Dyfed-Powys Police online, by calling 101 quoting reference 25000766626. Alternatively, information can be passed anonymously to Crimestoppers on 0800 555 111.

Teenager faces multiple charges after series of alleged incidents
Youth accused of assaults on police, criminal damage and railway trespass
A TEENAGE boy has appeared before the courts charged with a series of alleged assaults, public order offences and criminal damage incidents said to have taken place in Haverfordwest over several days in December.
The youth, who cannot be named for legal reasons due to his age, is accused of multiple offences alleged to have occurred between Wednesday (Dec 11) and Monday (Dec 16).
The charges include several counts of assault by beating, obstructing or resisting a police officer, using threatening or abusive behaviour, and criminal damage involving property valued at under £5,000.
It is alleged that a number of the incidents involved police officers acting in the execution of their duty. One charge relates to alleged trespass on or near a railway, while another concerns an arrest for an alleged breach of the peace.
The teenager appeared before the Youth Court, where reporting restrictions were confirmed under Section 49 of the Children and Young Persons Act 1933, preventing the publication of any information likely to identify him.
The court made further directions in the case, and the youth was remanded on conditional bail pending future hearings.
The case remains ongoing.
