UPDATE: The wife of a doctor found dead at his home in Feock has been charged with his murder.
GP Geriant Hughes, known as Gary, was discovered with stab wounds last Friday.
His wife Marion Hughes was arrested on suspicion of murder before being taken to hospital for treatment of injuries she had sustained.
Mrs Hughes, 58, was released from hospital on Tuesday and taken into custody.
Police confirmed this morning that she had subsequently been chraged with murder. She is due to appear before magistrates in Truro this morning.
Detective inspector Ben Beckerleg said: "This is the beginning of an investigation, but early indications suggest this was a domestic incident and no-one else is being sought at this time. An investigation had now begun to fully understand the circumstances and events leading up to this man's death."
If anyone has any information about this incident call 101 quoting log 124 of 15 November.
Tributes have been paid to Mr Hughes by family.
They said: “We are devastated by the tragic loss of our devoted and caring father. He was always there for us and we cannot believe he is gone. The last time we were all together was at the wedding just six weeks ago. We will always cherish the happiness we shared as a family that day.”
Mr Hughes was the son of two doctors, well known locally and now deceased, and came from a large family with six sisters.
Sister, Radio Cornwall presenter, Nina Davey, said described Mr Hughes as an amazing big brother and a brilliant dad, as well as being a well respected GP.
One male neighbour, who did not want to be named, said: “We’ve only been here 3 ½ years but he was extremely nice to us when we arrived and came and visited us and welcomed us.”
He described the couple as “a very nice couple who had no problems at all, who kept themselves together.”
“He was bought a new SLK car for his 60th birthday and they rode round in it together. They seemed very happy.”
Mr Hughes, who was the senior partner at the Clinton Road Surgery in Redruth, qualified in 1977 and was a member of the Royal College of General Practitioners.
The surgery website listed his professional interests as obstetrics and family planning, and said that in his spare time he liked to go sailing.
Joy Adamson, practice manager, said: “All the doctors and staff are truly saddened at the loss of a much loved colleague and friend.
“He worked at the surgery for over 30 years and will be sorely missed by the doctors, staff and patients and we would like to send our condolences and best wishes to his family.”
