A man has been found guilty of murdering a convicted child killer.
Ieuan Harley, 23, killed David Gaut after discovering he had been jailed for the murder of a toddler in 1985.
Harley and Darran Evesham, 47, were also found guilty of perverting the course of justice after attempting to conceal evidence from the attack.
David Osborne, 51, was cleared of both murder and manslaughter but had earlier pleaded guilty to perverting the course of justice.
The jury at Newport Crown Court took over five hours to return their verdicts on Monday afternoon following a three-week trial.
Gaut had moved into a flat next door to Harley's friend David Osborne in the village of New Tredegar after being released from prison.
He had told people he had been in prison for murdering a soldier - but his neighbours discovered the truth after searching the internet.
The court heard Gaut was then lured to Osborne's house on the pretence of borrowing a DVD - only to be brutally murdered by Ieuan Harley.
At least one knife was said to have been used to kill Mr Gaut and a screwdriver was later used to stab his dead body, leaving him with injuries that were so gruesome pictures were deliberately kept away from the jury.
Gaut had been jailed for 32 years for murdering 17-month-old Chi Ming Shek in 1985.
He was released on parole in November 2017.
The toddler's mother, who was then aged 23, had been out drinking and left Gaut to look after her two young children.
The the next day she found her son's dead body under a chest of drawers in his bedroom.
The boy died of multiple injuries including a broken arm, injured liver and spleen and a fractured skull.
During sentencing in 1985 Mr Justice Caldfield described the torture and murder of the toddler as "the worst crime in the land", adding: "The person murdered was a defenceless little baby and on the jury's finding you not only murdered that child but also tortured him."
In his police interview Osborne, of Long Row, admitted Mr Gaut had been killed in his flat and admitted helping to clean the flat and get rid of bloody clothes but he said he did this because he was scared of Harley, who he blamed for the murder.
During the trial Osborne claimed Harley was responsible for killing Mr Gaut in his flat while he was in the kitchen and said he saw his co-accused holding a knife over Mr Gaut’s dead body when he came out.
Harley, of no fixed abode, denied being responsible for Mr Gaut’s murder but claimed he had punched him and gave him a bloody nose three days before his death, which he said was the reason for Gaut’s blood being on his clothes.
Justice Clive Lewis said: “This is a serious matter, the sentence for murder is life and I have to fix the minimum term before a person can apply for parole.
“I will be prepared to delay sentence just in case there’s some psychiatric material in some way relevant in fixing the tariff.”
Harley, Osbone and Evesham will be sentenced at Newport Crown Court on 25 March.
