Top horror cases deciphered by science after more than 20 years

The couple Peter and Gwenda Dixon were murdered with a shotgun while walking on a coastal road in the summer of 1989. Their bodies were later found hidden near a coastal road, on a beach. 60m high cliff. Mr. Dixon’s hands were tied behind his back. His wife, the only wear.Police believe she was sexually assaulted. Their bank cards were used to withdraw money, indicating that Mr. Dixon was forced to give out his pin number by the killer. The police got involved again, but no one was arrested. Many readers called the BBC’s crime-monitoring department, while detectives made close to 4,000 notices. Case This really became a real-life mystery when investigators had to consider people who had dived in the bay, even had to zoom in on a photo of a cow found on the Dixon couple’s camera to find out. find the number on its ear and find the owner, or investigate all the people who signed the notebook in the nearby church with no clue.Detectives even looked between the killer and the Irish Republican Army (IRA) for a link after finding several weapons buried near where the victim’s body was found. Were the Dixons murdered after an incident with the IRA because they were smuggling weapons to west Wales?One mystery case Others also reached a stalemate when the bodies of Richard and Helen Thomas, 58, were found in the ruins of a farm near Milford Haven, nearly 10 meters from where the Dixons were killed. They were killed by a shotgun. At the peak of the investigation 1 year later, up to 150 officials and employees were involved but to no avail.In December 1998, John Cooper, a former farm worker and welder, was sentenced to 16 years in prison for armed robbery and 30 burglaries.Police discovered that the man had used the fence around his home near Milford Haven as a place to hide valuables, tools and weapons, including a handgun made in Belgium. He had carefully prepared the exit by cutting holes in the fence. However, police did not find a link between Cooper and the murders and sexual assault mentioned above.In 2006, Dyfed-Powys (Welsh) police established Operation Ottawa to review all available evidence. In 2008, police questioned Cooper again for four days in a row, but Cooper still pleaded not guilty. Even so, the results of genetic testing in 2009 showed a link between Cooper and the brutal murder case above.The scientists then re-examined 600 exhibits, especially a Belgian-made pistol. They found under the black paint of this gun a drop of blood that matched the blood sample of the victim Piter Dixon.The pair of shorts found at Cooper’s house when he was arrested for theft also denounced him. There was a blood stain on the right leg of his pants, which was confirmed to be Peter Dixon’s blood after scientists examined it. On the hem of the pants was a liquid that matched the DNA of Dixon’s daughter Julie.Police confirmed that when Cooper killed Mr. and Mrs. Dixon, his pants were stained with blood, so he had to wear Mr. Dixon’s pants to go home and continue to use these pants. The results of the DNA test showed that the IRA had nothing to do with these murders. The mysterious divers in the bay near the scene were also not involved.In the face of incontrovertible scientific evidence, Cooper bowed his head to plead guilty. Thus, 20 years after Mr. and Mrs. Dixon was killed and 24 years after Mr. and Mrs. Thomas was shot this arrow was executed.John William Copper was born in Milford Haven, Pembrokeshire, Wales on September 3, 1944. After leaving school at the age of 15, Cooper took on a number of odd jobs. At the age of 22, he married a woman named Patricia and had two children, Andrew and Theresa.In 1978, for winning a contest in the newspaper Spot the Ball, Cooper was awarded a car and £90,000. But soon, he plunged into the road of gambling and drinking. A friend of Cooper’s said: “He poured most of his winnings into pubs and bookies. He often fights so people don’t dare to get close.” The winning amount was exhausted when Cooper started the road of robbery.>>>Watch more videos: The mystery of the abandoned mansion, inside is a hundred-billion-dollar warehouse.
