A second man has been convicted of killing a banker in front of his family during a robbery at their London home.
White posed as a postman to get access to the high-security house
Elliot White, 24, was found guilty of the manslaughter of John Monckton, last November - but was cleared of murder.
White had admitted robbery but said he never agreed to take part in a killing - his accomplice Damien Hanson, 24, was convicted of murder on Thursday.
There have been calls for an inquiry into Hanson's early release from a 12-year sentence for attempted murder.
The jury is still trying to decide whether White, from Shepherd's Bush, west London, is guilty of the attempted murder of Homeyra Monckton, 46 - a charge he denies.
Jurors will resume deliberations on Monday.
Prosecutor Richard Horwell told jurors the attack was "every householder's nightmare".
Hanson and White, who were childhood friends, burst into the house, in Upper Cheyne Row, Chelsea, early in the evening on 29 November 2004.
White had tricked Mr Monckton into opening the door of the heavily-secured house, described as "like a fortress", by posing as a postman with a parcel.
Hanson, who was said to be obsessed with wealth stabbed Mr Monckton in the heart and lung and his wife twice in the back, before "calmly and coldly" demanding her jewellery.
The couple's daughter Isobel, 9, rang the police after the robbery.
Her father died soon afterwards but Mrs Monckton survived although she still requires a stick as a walking aid.
John Monckton was repeatedly stabbed by Hanson
During the trial, a taped police interview was played to the court in which White admitted knowing Mrs Monckton would be at home.
But he added: "I don't stab people. I don't do that type of thing."
The trial heard White told police he had been restraining Mr Monckton when "another person" attacked him - and that he thought the banker was being punched, not stabbed.
He said he pulled away only to be attacked himself by the knifeman. Some of White's blood was left at the scene.
Hanson, who was masked during the attack, had claimed he was never at the Moncktons' house that night and had been visiting his sister in Brixton.
But the jury did not believe him and convicted him unanimously of murder and robbery. He was also convicted of the attempted murder of Mrs Monckton by a majority of 11 to one.
During the trial they were told of Hanson's criminal record - he had only been released from jail three months earlier, after serving just over half of a 12-year sentence for attempted murder and robbery.
Referring to Hanson's early release, Harry Fletcher from the National Association of Probation Officers, called for an independent investigation into Hanson's "extremely serious offence".
The inquiry should look at the reasons for the parole decision and any findings should be acted on immediately, he said.
