Barry McCarthy guilty of wife Lorna's murder
A man has been found guilty of the murder of his estranged wife in what police called "a horrific attack".
Barry McCarthy, 50, admitted killing Lorna McCarthy, also 50, at their home in Gorleston-on-Sea, Norfolk, in September but denied murder.
The couple had separated four months earlier but continued to live together, while sleeping apart.
McCarthy was found guilty at Norwich Crown Court following an eight-day trial. He will be sentenced on 1 May.
Following their separation, McCarthy discovered that his wife had been using dating websites. He confronted her about it and she agreed to delete her profiles, Norfolk Police said.
On September 27, they had an argument and she sent text messages to friends and family saying she feared for her life.
In one sent to her daughter Kerrie Oates, she asked her to call police if she did not hear from her the next day.
She added: "I'm quite serious as I really don't know what he is capable of these days."
Her daughter never received the message.
Later the next day, McCarthy handed himself into police, telling them he had killed his wife, Norwich Crown Court heard.
Officers went to their home and found Mrs McCarthy in the back bedroom. A post-mortem examination revealed she had died from a stab wound to the heart.
McCarthy pleaded not guilty to murder on the grounds of diminished responsibility.
Det Ch Insp Paul Durham said: "This was a horrific and brutal attack on a woman in her own home by a man she had spent 25 years of her life with.
"My thoughts go out to Lorna's family and friends, and I hope today's verdict will help bring them some comfort as they still try to come to terms with her tragic death."
In a statement on behalf of the family, Mrs Oates described her mother as a "bright and beautiful woman who lit up the world".
She added the family was "absolutely devastated and heartbroken" but "pleased that justice has prevailed and the murder charge has been upheld".
