A man has been found guilty of murder after he repeatedly stabbed a guest who had offered him money for sex.
But the South Australian Supreme Court jury acquitted a co-accused, who slit the stabbed man's throat.
Instead of murder, the jury found Luke James Hutchings, 30, guilty of assisting an offender by helping to clean up the scene and dispose of Andrew Negre's body.
Hutchings and Michael Joseph Lindsay, 29, had denied murdering Mr Negre, 37, whose dumped body was found in an Adelaide reserve on April 8, 2011 about a week after he died.
The jurors, who returned their verdicts late on Thursday, were told Mr Negre had gone back to Lindsay's house for a social gathering.
Witnesses said Lindsay became enraged Mr Negre made an unwanted sexual gesture and offered him $200 for sex.
Hutchings told the jury that after his housemate punched, kicked and repeatedly stabbed Mr Negre, he had looked at Hutchings while still holding the knife in his hand.
Hutchings said he thought he might be next, so he grabbed the knife and slit the throat of Mr Negre, whom he believed was already dead.
His lawyer contended while his client's actions were extraordinary and appalling, they were believable.
He said Hutchings had been reacting to his housemate turning into "a homicidal maniac" in an episode of sudden "cyclonic fury".
Looking at the situation clinically, Hutchings achieved the desired result by disarming Lindsay and did not further harm Mr Negre, who was already dead, the lawyer said.
Lindsay's barrister had submitted the jury could find Lindsay guilty of manslaughter on the basis of his being provoked by Mr Negre.
The case will return to court on August 30.
