Deirdre Morley found not guilty by reason of insanity of the murders of her three children
The jury have returned their verdict.

LAST UPDATE | May 20th 2021, 3:58 PM

PAEDIATRIC NURSE DEIRDRE MORLEY has been found not guilty by reason of insanity of the murders of her three children. 

The 12 jurors accepted the evidence given by two psychiatrists that the accused, who specialised in renal care at Our Lady’s Hospital in Crumlin, was suffering from a mental disorder at the time of the three killings and fulfilled the criteria for the special verdict.

The case, Deirdre Morley’s defence counsel had told the jury, was a “tragedy of enormous proportions”, with the “tragic irony” of the accused being someone who had committed her entire professional life to the care of children as a paediatric nurse.

The two consultant forensic psychiatrists called as expert witnesses were both in agreement that the accused was unable to appreciate what she had done was morally wrong and was unable to refrain from her actions

In his closing speech, defence counsel Michael Bowman SC said the case was a “tragedy of enormous proportions” that had been visited upon parents who were “utterly committed” to the welfare of their children.

He stressed that the tragic loss of three children was at the core of the case and their parents had been left in a set of circumstances where their offspring were no longer with them. It was clear, he said, that his client was labouring under a mental illness which was defined within the Criminal Law Insanity Act 2006.

Bowman suggested that one of “the tragic ironies” in the case was that the accused had committed her entire professional life to the care of children as a paediatric nurse and bore that responsibility heavily on her own shoulders but had suffered from depression and anxiety since the late 1990′s.

“Despite the best efforts of those around her and the level of support they offered, it was not enough to prevent her slipping into a state of delusion and psychosis from which she could not return,” he remarked.

The three-day trial at the Central Criminal Court, which the State called “a desperately sad case”, heard that Morley had unsuccessfully attempted to drug her three children on the previous day, having formulated a plan to then suffocate them in their sleep.

The 44-year-old highly trained clinical nurse, of Parson’s Court, Newcastle, Co Dublin, had pleaded not guilty by reason of insanity to the murder of her sons Conor McGinley (9) and Darragh McGinley (7) and her daughter Carla McGinley (3). The children’s bodies were discovered at the family home just before 8pm on January 24 last year.

The trial was told that Darragh was the first child to be killed and there had been a disagreement that morning over the amount of “screen time” he was watching on his iPad and the television.

After killing Darragh she then smothered her daughter Carla. After collecting her eldest child Conor from school and bringing him to Tesco, she brought him home where he was also killed. She left him inside the room downstairs while his siblings’ bodies had been brought upstairs.

Assistant State Pathologist Dr Margot Bolster found the children had died by asphyxia from compressions of the chest area and airways.

Morley had made “crystal clear” to gardaí in her interviews that she wanted to make sure that she “was gone” after she killed her children and before her husband arrived home that evening.

She left her home after 4pm. However, she crashed her car in a grassy area and lost consciousness. She left the house again on foot at 6.30pm but was found by a taxi driver, who gave her a lift back to the estate.

After returning from an overnight work trip in Cork, the accused’s husband Andrew McGinley found his wife unconscious and being cared for by paramedics in the estate. He then discovered the bodies of his three children in the house. Darragh and Carla were found upstairs in the master bedroom and Conor was downstairs.

Two notes written by the accused had been left in the house, with one placed at the bottom of the stairs, to urge whoever came through the door of the family home not to go into the front room or upstairs and to phone 911 instead.

Mental state

Dr Brenda Wright, called by the defence, gave a detailed description of the accused’s mental state deteriorating in the weeks before the killing and said she was suffering with bipolar affective disorder at the time. The witness said the defendant believed it was morally right to smother her three children as she thought she had “irreparably damaged” them and “had to put an end to their suffering”.

Dr Mary Davoren, for the prosecution, testified that the accused was suffering at a minimum from recurrent depressive disorder and experienced a severe depressive episode on the day.

Morley told gardaí that she was feeling “overwhelmed” at the time, her thoughts had been “getting darker” that week and she wanted to save her children from the “pain and suffering” she felt lay before them because of her shortcomings as a parent. She believed she had to take their lives as they were “more damaged” by her parenting skills and they “had to go together”.

The defendant, the court heard, had previously found it difficult to cope with stress at work and had taken the loss of a child in her ward particularly badly.

In his charge to the jury, Mr Justice Paul Coffey said there was “no contest in this sad and tragic case” about what the correct verdict should be. He said the evidence was all one way and both the prosecution and defence agreed that the defence of insanity applied.

One hour and 28 minutes into their deliberations, the jury asked Mr Justice Coffey for clarity on the special verdict of insanity. He told them that the case is “unusually free from controversy of any kind” and was one in which it is agreed that the special verdict of not guilty by reason of insanity should be returned on all counts.

The jury of ten men and two women spent four hours and 23 minutes deliberating over two days before bringing in three verdicts of not guilty by reason of insanity.

After they had delivered their verdict, Mr Justice Coffey thanked the jury for their service saying: “I’m aware this was a very disturbing case for everyone involved and it must have had a very great impact for everyone of you. I want to thank you on behalf of the people of Ireland.”

The judge exempted them from jury service for the next 15 years.

He then made an order committing Ms Morley to go to the Central Mental Hospital today and for the matter to be brought back before the court on May 31.


In her opening address, prosecuting counsel Anne-Marie Lawlor SC said the jury’s primary concern would be the accused’s mental state on January 24 and there was no issue in the case as to what happened to the children and how they died.

The accused’s mental health had deteriorated very significantly and she suffered a breakdown in July 2019. She was admitted to St Patrick’s Hospital in Dublin as an inpatient for four weeks. Those closest to Ms Morley had sought to manage her problems as best they could but didn’t realise the gravity of the situation.

“In the days before the children’s deaths, there was a belief that her mental health had improved significantly and psychiatrists will assist you in that was not the case,” indicated Ms Lawlor.

The court heard that both Clondalkin Mental Health Services and the Swiftbrook Medical Centre had written to St Patrick’s Hospital requesting that Deirdre Morley be readmitted due to concerns about her mental health.
