The Bullseye Game Show Killer: The Chilling Crimes of John Cooper
The Game Show That Caught a Serial Killer

John Cooper: The Bullseye Serial Killer in The UK — A chilling account of John Cooper’s crimes, including the shocking details of his murders and the role a game show appearance played in his capture.
John Cooper: The Bullseye Serial Killer
John William Cooper, the notorious “Bullseye Serial Killer,” left a trail of tragedy and terror in the United Kingdom with his appalling crimes. Born in 1944 in Wales, Cooper’s early life was marked by a series of criminal activities, including approximately 30 robberies and violent assaults, which were exacerbated by a substantial gambling habit. This troubled background laid the foundation for the heinous acts that would later earn him notoriety as one of the most infamous serial killers in the UK.
John Cooper’s criminal activities escalated into a string of brutal murders that shook the nation. In 1985, he callously took the lives of siblings Richard and Helen Thomas, and in 1989, he committed the double murder of Peter and Gwenda Dixon. The magnitude of these crimes was further compounded by his attack on five youngsters, which involved sexual assault and rape. The impact of these crimes reverberated throughout the victims’ families and the wider community, leaving a lasting scar on the fabric of UK society.
The Game Show “Bullseye”
Cooper’s appearance on the game show “Bullseye” in 1989 holds a chilling significance in the context of his criminal activities. His seemingly jovial demeanor on the show, where he casually shared details that later became crucial in the criminal investigation, added a disturbing layer to his already dark and sinister persona. The comparison of his appearance on “Bullseye” with his malevolent criminal history reveals a stark picture of his character’s complex and deceitful nature.
The investigation into John Cooper’s crimes was a meticulous process that relied on a variety of evidence to link him to the murders. His physical appearance bore a striking resemblance to a police sketch of the murderer, and his hobby of scuba diving on the coastline provided critical clues that placed him at the scene of the crimes. Additionally, tiny traces of blood found on clothing from his home became vital pieces of evidence in solving his crimes. These meticulous investigative efforts underscore the dedication and perseverance of the law enforcement agencies involved in bringing Cooper to account for his appalling deeds.
In 2009, the investigative efforts of law enforcement resulted in Cooper’s arrest, followed by a trial and life sentence being handed down in 2011. The pivotal role played by the “Bullseye” tape and forensic evidence in his trial underscored the significance of leveraging technological advancements in forensic techniques to secure convictions in complex criminal cases.
The Impact
The impact of John Cooper’s crimes reverberated beyond the tragic loss of innocent lives, spurring significant changes in the UK criminal justice system. His case underscored the imperative of reevaluating cold cases and leveraging advancements in forensic techniques to effectively pursue and successfully close these cases. The continued pursuit of cold cases ensures justice for the victims and the safety and security of the public.
Cooper’s Sentence and Claim of Wrongful Conviction
Currently serving a life imprisonment sentence, Cooper still claims he is wrongfully convicted. Cooper has applied as recently as April 2023 to the Criminal Cases Review Commission (CCRC), marking another chapter in the ongoing saga of his case. The CCRC’s pivotal role in reviewing criminal instances where individuals believe they have been wrongly convicted or sentenced underscores the complexities of convictions like Cooper’s. Such cases motivate law enforcement to do their best to protect the investigation’s integrity and conviction.
