A man has been convicted of murdering a prison officer in a punishment attack.
Mr Chapman also worked as a doorman
Mark Dorling, 37, of Crystal Palace, south London, stabbed Aaron Chapman in the chest at his Sutton home in 2002.
The Old Bailey heard Mr Chapman, 23, was a body builder who often cheated on women and was suspended from his prison job for moonlighting as a bouncer.
James Pearson, 38, from Surrey, was cleared of murder but convicted of conspiracy to wound. John Gordon, 34, of Croydon, was cleared of all charges.
Dorling and Pearson will both be sentenced on Friday.
No-one knew the exact motive for his murder, but Mr Chapman's extra-curricular activities and the company he kept was thought to be behind it, the jury heard.
David Williams, prosecuting, told the court there were rumours circulating that Mr Chapman was too close to some of the prisoners at High Down Prison in Sutton, that he was supposed to be guarding.
It was also alleged he had had an affair with the wife of at least one serving prisoner.
"There were whispers he might be involved in bringing in drugs or other contraband," said Mr Williams.
"He was described as charming but immature. His charm made him a favourite with women.
"He had a series of relationships with women - many at the same time. He had a capacity for deception which made this successful," he added.
On December 10, 2002, Mr Chapman called the emergency services to his home, saying he had been stabbed.
Ambulance and police crews found him alive and conscious but covered in blood with a 7in (17.8cm) wound to his chest and heart.
The next day, despite an operation to save him, he died.
