A former British Olympic diver found shot dead along with his wife at their Spanish villa was originally from Brentford.
Peter and Jean Tarsey, both 77, were discovered locked in each others' arms on the sofa of their home in Xalo, near Benidorm, on Sunday (March 29) afternoon.
Detectives believe the couple, who had lived on the Costa Blanca for more than 20 years, were shot at point blank range with a pistol.
Peter, known locally as David, competed at the 1956 Melbourne Olympics and won Commonwealth bronze for England two years later in the springboard.
Jean, originally from Camberley, Surrey, was described by friends as a keen charity worker and Reiki healer.
On Tuesday, British Swimming sent its "warmest condolences" to the family of the couple, who had two sons, Alexei and Sascha.
The Tarseys' home had reportedly been burgled twice previously and police are investigating whether they were killed in a bungled robbery, although there were apparently no signs of a break-in.
A friend described them as a "lovely couple" and said everybody who knew them was "absolutely devastated".
She said Peter had been an engineer back in the UK, selling his business when he and Jean moved to Spain in 1990.
The couple's home, which had a large swimming pool and mountain views, had been up for sale since last year.
