A headteacher who killed his "bullying" wife, sawed her body up and hid the remains in a freezer has been convicted of manslaughter but cleared of murder.
Dalton said he was bullied by his wife and treated like a slave
Paul Dalton, 35, from Kingston, Surrey, told the Old Bailey he killed Tae Hui by accident after years of torment.
He said the 38-year-old had taunted him over an affair and he "lashed out" in a "blind panic" when she lunged at him.
Dalton admitted killing his wife but denied murder. He is due to be sentenced on Monday.
'Scared of her'
The defendant always maintained he accidentally killed his Korean-born wife, denying prosecution claims he left her to die.
Dalton, who said she treated him like a slave, told the jury: "She always got what she wanted. I was scared of her. Everyone was scared of her."
The couple ran a language school in Kingston that he set up, but the defendant said she denied him a wage and also took his passport to stop him leaving, stalking him when he tried to escape.
During the fateful row, he said his wife told him she had only married for "the visa".
After the violent scuffle, Dalton went upstairs and returned to find blood coming from her mouth. Cause of death was given as inhalation.
'She was gone'
"She was not breathing. I looked into her face and she was gone," he said.
Later, he bought an electric saw, a bow saw and dust sheets before chopping the body into nine pieces and put them in a fridge-freezer in the kitchen.
Dalton, a teetotal computer specialist, was traced by police to Japan after his parents visited his home as they had not heard from him and discovered the body.
He told the court he had fled to make sense of what had happened, saying his "brain was on fire".
Dalton admitted killing his wife - who he met in 1994 and married three years later - and preventing her burial.
The jury convicted him of manslaughter on the grounds of lack of intent (to murder) after less than an hour's deliberation.
