article: A British woman told today of her horror at finding her two best friends shot dead on a sofa at a villa in Spain. Peter Tarsey and his wife, Jean, both 77, were found covered in a green raincoat, each killed with a single bullet in a double murder of 'terrible cruelty'. The friend, Ann, said she had gone to the house on Sunday afternoon with another friend because she was concerned at not being able to reach the couple on the phone. The expat, who had been friends with the couple for 25 years, said: 'I knew something was wrong as soon as we got there. What we found was like something out of your worst nightmare. Murdered: Peter Tarsey and his wife Jean, both 77, were killed with a single bullet each while locked in each other's arms under a raincoat on their sofa in their detached country home in Xalo, near Benidorm . Grim: Police were alerted on Sunday at 4.15pm when friends went round to the house for their regular Sunday dinner. They found the door open and the couple dead in each other's arms on the sofa in the front room . 'I'm still in a state of shock. Both the couple's cars were there, so we knew they must be in the house. 'We climbed over the fence and found the kitchen door open. I knew as we entered the house something was terribly wrong. 'We saw them on the sofa covered in a green raincoat that Jean had recently bought. 'They were covered up but their legs were visible at the bottom of the coat. 'We knew it must be them but Eduardo wanted to make sure, so he pulled the coat back just to check. 'They were in each other's arms like he was protecting her. I really don't want to think about it as it's so upsetting.' A murder investigation has been launched after Jean (pictured) and Peter Tarsey, both 77, were found shot dead inside their villa in Spain on Sunday . While police say they are not ruling any lines of inquiry out, they believe the couple were murdered . Ann, who asked for her surname not to be published, said she 'can't imagine' who would want to kill them, adding: 'They were such a lovely, friendly couple who would do no harm to anyone.' She said: 'I really hope the police catch whoever was responsible and throw away the key. 'It didn't look like a robbery as the house looked normal. There were none of the disturbances you would associate with a robbery.' Ann and her friend, Eduardo Juan, found the couple at around 4pm on Sunday at the couple's house in Xalo, near Benidorm on the Costa Blanca. Their dog Domino was inside barking when they arrived. The four friends went out for lunch every Sunday and Ann became concerned when she could not raise them on the phone. Mr Tarsey always went by his middle name of David. The couple, pictured together the day before they married in February 1960 . A 15-year-old Mr Tarsey practises his diving at a pool in London, four years before competing at the Olympics . She added: 'David was an Olympic diver and Jean was a swimmer. They met when they were 13 at a diving club in England and were childhood sweethearts. 'Who could do such a thing to a defenseless elderly couple? As far as I know they had no enemies and were not overly concerned about burglaries. 'There have been some robberies not far from Xalo in recent years and they have been getting more violent, but this is just terrible. I can't imagine anything worse. 'Their sons Alexei and Sascha are absolutely devastated.' Eduardo told a local Spanish newspaper of the moment he lifted the raincoat up. He told Las Provincias: 'From the shock I got, my legs are still trembling. 'The bodies were covered with a raincoat but the legs were sticking out. 'He was hugging her, on top of her, as if he were protecting her, because my impression is that they had an extremely cruel death. 'He was such a good person, I'm sure if they had asked for money or something very valuable, David would have given it so they didn't hurt his wife.' The killer or killers threw the couple's computer into the swimming pool (above), possibly out of fear it contained images captured on the couple's webcam . Eduardo told the paper he had known the Tarseys for 40 years, adding: 'They were very good people, humble, friendly and not ostentatious. Everyone who met them loved them. 'We called the Tarseys' sons, Alexei and Sascha, at 10.30 that night to inform them of the deaths of their parents. It was horrible.' Police have revealed that Mr Tarsey was shot in the back of the neck while Mrs Tarsey was shot in the face. The killer or killers threw the couple's computer into the swimming pool, possibly out of fear it contained images captured on the couple's webcam. Police said they are still investigating the motive for the murders, but believe it may have been a bungled robbery. A television was stolen, but police denied reports that an attempt had been made to force the couple's safe. No gun was found at the property, but police believe the murder weapon was a small pistol. The Tarseys, originally from West London where Mr Tarsey worked as an engineer, bought their Spanish home in 1990. They had put it on the market for €230,000 (£170,000) last year, hoping to move to Majorca to be closer to their son Sascha, a friend said.
