A mother-of-two was strangled to death by her partner of four months after a "binge drinking session" during which both of them were arrested and released, a barrister has told the Central Criminal Court.
Amanda Carroll's body was found in her bedroom the following afternoon by her then 16-year-old son, who had left the house that morning to play football not knowing she was dead.
Earlier this week, Sean Nolan (36) of Ashington Crescent, Navan Road, Dublin, pleaded not guilty to murdering Ms Carroll (32) at her home in Homestead Court, Quarry Road, Cabra, Dublin 7, on October 21, 2018.
Yesterday, the accused was re-arraigned in front of a jury of six men and six women and pleaded guilty to her manslaughter, but not guilty to murder.
Opening the trial Shane Costelloe SC, for the prosecution, said Mr Nolan's plea means he accepts he killed Ms Carroll.
But, counsel said, the prosecution case is that when Mr Nolan "put his hands on the throat and mouth of the deceased" he intended to kill or cause serious injury and is therefore guilty of murder.
"You have to decide whether we have proven that he intended to kill or cause serious injury when he killed her," Mr Costelloe told the jury.
Outlining the case, he said the deceased began a relationship with the accused about four months before her death.
It was a "volatile" relationship, he said, "that seems to have arisen with excessive consumption of alcohol".
The day before she died the couple went on a "binge drinking session" that started early in the day and continued throughout Dublin city and county.
At about 5.30pm on October 20, Mr Nolan was driving his car but due to his intoxication he crashed and was arrested, counsel said.
Ms Carroll was arrested for an alleged public order offence.
They were detained for a couple of hours and released at about 8pm that night.
Mr Costelloe said the jury will hear they continued their drinking and were seen between 10pm and 11pm by people who described Ms Carroll as being "highly intoxicated".
A taxi driver took them back to Ms Carroll's home where they were caught on CCTV entering the apartment complex.
The following morning at about 10am, Ms Carroll's son Denis (18), went out to play soccer. When he arrived back home that afternoon, he went into his mother's room and realised she was dead.
The accused, Mr Costelloe said, had left the apartment earlier and was seen walking around Dublin 7.
When gardaí were alerted they found Mr Nolan and brought him to a garda station where he was questioned.
Mr Costelloe said the accused accepted he put one hand over Ms Carroll's mouth and another around her neck when they were lying in bed that night.
The trial continues.
