A 30-year-old man has gone on trial charged with the murder of a musician in Sligo in August 2015.
Keith Brady of Cartron Estate, Sligo has admitted killing 59-year-old Martin 'Matt' Kivlehan at his apartment on Holborn Street in the town between 2 August and 3 August 2015, but he denies murdering him.
His plea of not guilty to murder, but guilty to manslaughter, was not accepted by the Director of Public Prosecutions.
The jury was told Mr Kivlehan lived on his own in Sligo, but people would occasionally visit him for a drink.
Senior Counsel Paul Murray told the court certain facts would not be in dispute.
He said Mr Brady and his sister Janice were in Mr Kivlehan's house when Mr Kivlehan died.
He said Mr Kivlehan died as a result of two stab wounds, one on either side of his neck.
Death would not have occurred immediately, the court heard, but would have occurred rapidly as a result of haemorrhaging blood.
Mr Murray said Mr Kivlehan had very high levels of alcohol in his blood and was "grossly intoxicated" when he died.
His body was found the following day when someone called in to the apartment.
The seven women and five men on the jury were told they would have to decide whether the killing of Mr Kivlehan amounted to murder or manslaughter.
Mr Murray said they would have to decide what the natural and probable consequences were of stabbing someone not once, but twice, on either side of the neck.
He said they would also have to decide if Mr Brady intended to kill or cause serious injury to Mr Kivlehan.
The case is expected to finish next week.
