A jury at the Central Criminal Court today found electrician Sean Nolan (36) guilty of murdering Amanda (36) at her apartment in Cabra, north Dublin, on 21 October 2018.
The court heard he violently attacked her after she called him by the name of her ex-boyfriend and told him she never loved him.
Just days before killing her, Nolan had posted a series of pictures of Amanda online saying how he loved her. He added that he was “in the right place now” and apologised for past behaviour.
Amanda posted under the pictures saying Nolan was the “love of my life”.
After being congratulated by a pal, Amanda wrote: "Tanks hun his [he's] the best."
But days later, Nolan viciously turned on her at the flat on Homestead Court.
He choked her until he killed her before fleeing the flat and later told gardai her had put his hand on her neck and mouth “to get her to shut up”.
Nolan will be given a mandatory life sentence next Wednesday.
Today, the Central Criminal Court jury has found an electrician guilty of murdering his partner of four months, whom he strangled in her bedroom after a "binge" drinking session.
The panel of six men and six women rejected the defence contention by a majority verdict that Sean Nolan (36) that what had happened to the mother-of-two was an "accidental death".
Defence counsel Michael O'Higgins SC with Garrett McCormack BL had asked for a verdict of manslaughter on the grounds of lack of intent due to alcohol intoxication.
Instead, the jury accepted the State's case that there could be no doubt that Nolan intended to kill or cause serious injury when he put his hand around Ms Carroll's neck for 20 seconds.
In his closing speech, prosecution counsel Shane Costelloe SC with Caroline Cummings BL argued that drunken intent was still an intent and one can decide in a split second to kill or cause serious injury to someone when they have alcohol taken.
Evidence was given that the couple went on a "binge drinking session" that started early in the day and continued at different locations throughout Dublin into the night.
The accused and Ms Carroll were involved in a road traffic collision a few hours before the 33-year-old was killed and both fled the scene before being intercepted.
Nolan's bloods were taken as there was a concern he was drink driving or drug driving and Ms Carroll was arrested for a public order offence and had to be handcuffed with her hands behind her back after striking out at gardai.
However, after being detained in Mountjoy Garda Station for a couple of hours, the pair's drinking session continued into the night.
When the couple returned to Ms Carroll's apartment that night, Nolan put one hand on the neck of the mother-of-two and the other over her mouth after she called him by the name of her ex-boyfriend, said she never loved him and tried to hit him.
"I was angry. I just wanted her to go asleep and stop," the accused told gardai.
Nolan explained to detectives that he knew his girlfriend was dead when he woke up in her bed the next morning and had "just panicked" before he ran out of the apartment.
Ms Carroll's body was discovered in the bedroom of her apartment the following afternoon by her then 16-year-old son Denis Carroll who had left the house earlier in the morning to play football not knowing that his mother was dead.
Denis Carroll told the trial that he could see his mother was not breathing saying: "I could see her cheek was puffy and she was cold. I knew that I was not going to see her again."
The trial heard that gardai found Nolan on a North Dublin street after they identified the body of Ms Carroll, with the accused telling them that the couple had argued and he thought he had “choked her until she passed out" before falling asleep.
The defendant said he had "freaked" and spent the day walking around. When he was then arrested on the Navan Road and placed in a patrol car, Nolan said “I probably killed her” when told of Ms Carroll’s death.
The accused also gestured to the arresting officer how he had put his hand on his partner's neck and over her mouth "to get her to shut up."
Assistant State Pathologist, Dr Margaret Bolster, testified that Ms Carroll died from compression of her neck and mouth which was complicated by the ingestion of sedative type drugs.
Ethanol, Diazepine, sleeping tablets, alcohol, antidepressants and cocaine were detected in the deceased's system.
Dr Bolster pointed out that the mother's death could not have occurred without asphyxia but the drugs consumed had an added effect.
The 12 jurors found Nolan guilty of murder by a majority verdict of 10-2. They had deliberated for eight hours and eight minutes over five days.
Following today's verdict, Mr Justice MacGrath thanked the jury for the attention they had given the case. He exempted them from jury service for ten years.
Nolan made no reaction when the verdict was delivered.
Members of Ms Carroll's family said "yes" aloud when the verdict was announced by the court registrar.
Mr Justice MacGrath will hand down the mandatory sentence of life imprisonment on November 4 and remanded Nolan in custody until that date.
The judge directed the preparation of a victim impact report by Ms Carroll's family.
