Steven Ray found guilty of murdering Rory Hemming
A man has been found guilty of murder after stabbing another man with a knife picked up from a draining board.
Steven Ray, 36, of Thornburgh Road, Heeley, Sheffield, stabbed Rory Hemmings, 29, at a house in Errington Crescent in the city in November.
Mr Hemmings had gone to the house where his ex-partner lived and an argument with Ray escalated into a fight, Sheffield Crown Court heard.
Ray, who was in a relationship with Mr Hemming's ex, stabbed him in the chest.
Det Ch Insp Craig Jackson, of South Yorkshire Police, said Mr Hemmings was speaking to his ex-partner when Ray intervened and "the situation spiralled out of control".
Mr Hemmings collapsed after the stabbing and was pronounced dead at the address on the morning of Sunday, 15 November, he said.
A post-mortem examination revealed he died due to a single stab wound to the chest.
Mr Jackson said: "This is an incredibly tragic case where the jury were asked to decide upon whether the defendant's actions were proportionate in the circumstances.
"They clearly decided that this was not the case."
Mr Hemming's mother said: "I still can't believe he's gone and that his two daughters will have to grow up without their father.
"Rory had so many friends and was loved by everyone, he wasn't a bad person, he was just going through a very difficult time in his life, but he would have been fine."
Ray is to be sentenced at Sheffield Crown Court on Thursday.
