Scary cases are decoded by science

Modern inspection technology helps Wales police break down 4 murders and mysterious rape two decades ago.

The couple Peter and Gwenda Dixon were murdered with pistols while walking on a coastal road in the summer of 1989. Later they found their bodies hidden near a coastal road, on one cliff 60m high. Mr. Dixon's hand was tied behind. His wife, the only wear. Police believe she was sexually assaulted. Their bank card was used to withdraw money, indicating that Mr. Dixon had been told by the murderer of the pin code. The police came back, but no one was arrested.

Many readers have called the BBC 's criminal surveillance department, while detectives have issued nearly 4,000 announcements. This case really became a mystery in the midst of life when investigators had to consider those who had dived in the bay, even had to enlarge a picture of the cow found in the couple's camera. Dixon found the number on his ear and found the owner, or investigated all those who had signed the notebook in the nearby church without seeing any clues.

Detectives even considered the murderer and army of the Irish republic (IRA) to see if there was any connection after finding a number of submerged weapons near the place where the body was found. Is it possible that Mr. and Mrs. Dixon were murdered after the incident with the IRA because they smuggled weapons to western Wales?

Another mysterious case came to a standstill when the bodies of Richard and Helen Thomas , 58, were found in the ruins of a farm near Milford Haven, the way the Dixon spouses were killed. nearly 10m. They were murdered by a shotgun. At the peak of the investigation about a year later, there were 150 officials and employees who entered but had no results.

In December 1998, John Cooper, a former farm worker and welder, was sentenced to 16 years in prison for robbery and armed robberies.

The police found him using the fence around his house near Milford Haven as a hiding place for valuable property, tools and weapons, including a handgun made in Belgium. He carefully prepared the withdrawal line by cutting holes in the fence. He was proud of his ability to survive, so he wrote in his notebook and called it the " special forces air guide" . However, police did not find a link between Cooper and the murder and sexual assaults mentioned above.

In 2006, police Dyfed-Powys (Wales) set up the Ottawa Campaign to review all available evidence. In 2008, police again interrogated Cooper for four consecutive days but Cooper still pleaded not guilty.

Even so, the 2009 genetic test results show a link between Cooper and the brutal murder cases mentioned above.

Later, scientists checked 600 exhibits, especially Belgian-made pistols. They found under the black paint of the gun a drop of blood that matched the blood sample of the victim Piter Dixon.

A pair of shorts found at Cooper's home when the man was arrested for stealing also accused him. There was a blood stain on the right side of the pants, confirmed to be Peter Dixon's blood after the scientists checked it. On the contour of the pants there is a liquid that matches Dixon's DNA pattern, Julie.

Police claimed that when Cooper killed Mr. and Mrs. Dixon, his pants were covered in blood so he had to wear Mr. Dixon's pants to go home and continue using the pants. The results of the DNA assessment show that the IRA has nothing to do with these murders. Mysterious divers in the bay near the scene are not involved.

In the face of indisputable scientific evidence, Cooper bowed his head to plead guilty. Thus, 20 years after Mr. and Mrs. Dixon were killed and 24 years after the shot of Mr. and Mrs. Thomas were executed. In addition to murder, Cooper was also convicted for raping a 16-year-old girl and sexually assaulting another 15-year-old girl.
