An alcoholic murdered his partner by slashing him with a broken vodka bottle after downing 1.5 litres of spirits, a court heard.
Michael Riches, aged 55, bled to death after an artery in his wrist was severed by his partner Tony McCall, it is alleged.
In a 999 call played to a jury at Sheffield Crown Court, McCall could be heard telling the operator: “I think I’ve killed him.
“He was having a go at me. He just nagged, and nagged, and nagged, I can’t do anything right, and I just hit him. I think he’s dead.”
David Brooke, prosecuting, said: “On the evening of October 6 last year the emergency services received a 999 call from this defendant.
“He said it was an emergency and he’d had a go at someone, another man, and the man was bleeding. He told the operator he thought he had killed him.”
Mr Brooke said police attended and broke into Riches’ bungalow in Swinburn Place, Herringthorpe, Rotherham.
“They found Mr Riches unconscious on the settee in the living room. The defendant was sitting next to him and appeared to be drunk.
“There was a great deal of blood and broken glass, and Mr Riches had sustained a severe injury to his wrist. He had effectively bled to death.”
Mr Riches was taken to Rotherham Hospital after paramedics restarted his heart, but died at 5am the next morning.
Mr Brooke said the men had been in a relationship since 1978 but both were alcoholics.
“The background is one of domestic violence between the two, and years of heavy drinking by each man,” he said.
McCall, also 55, of Redscope Crescent, Kimberworth, denies murder.
The trial continues.
