Brian Ogbo, an Ireland-based Nigerian, has been sentenced to three and a half years in prison for the killing of Stella Nnadi, his 82-year-old grandmother, during what an Irish court described as a severe psychotic episode linked to untreated schizophrenia.
Ogbo, 39, was sentenced by the Cork Circuit Criminal Court after pleading guilty to the manslaughter of his grandmother at the family home in Carrigaline, County Cork, on February 23, 2025, according to an Irish Mirror report.
The court heard that Ogbo relocated from Nigeria to Ireland in December 2024 to reunite with his mother, Ruby Ogbo, and his grandmother after years apart.
During the proceedings, prosecutors revealed that Ogbo had been diagnosed with schizophrenia in 2017 but missed two scheduled anti-psychotic injections following his arrival in Ireland due to delays in accessing mental health services.
His mother, Ruby, a social worker, reportedly made several unsuccessful attempts to secure psychiatric treatment and medication for him.
Sinead Behan, presiding judge observed that the defendant was “clearly in the throes of a psychotic episode” when the fatal incident occurred.
Garda Tom Delaney, a detective told the court that Ogbo had spent hours pacing around the house before the attack, damaging parts of the kitchen and eating all the food in the home.
According to Delaney, tensions escalated after his mother confronted him over his behaviour and threatened to confiscate his phone and disconnect the house WiFi.
The detective said Ruby later removed the internet router from the house before attempting to leave, but Ogbo allegedly followed her with a pair of scissors.
“Ogbo pushed Ruby to the ground in the kitchen and punched her in the head while she was on the ground,” Delaney told the court.
The prosecution said Ogbo then went upstairs searching for his grandmother, who had locked herself inside a bathroom in fear.
“He shouted at her to open the door. The deceased shouted, ‘Oh my God, Oh my God,’” the detective recounted.
Ruby reportedly fled the house to seek help from neighbours after warning them that her son intended to kill her mother.
The court heard that Ogbo eventually forced open the bathroom door, dragged his grandmother downstairs and pushed her outside the house.
Although the elderly woman managed to escape to a neighbour’s home alongside her daughter, her condition reportedly worsened two days later.
Medical examinations later revealed bleeding on the brain, and she died in hospital on February 25, 2025.
A postmortem examination found that Nnadi died from blunt force trauma to the head caused by being forced down the stairs during the attack.
Jane Hyland, defence counsel, described the case as “a tragedy for the family and also a tragedy for Ogbo,” noting that the defendant had maintained a close relationship with his grandmother throughout his life.
Hyland argued that Ogbo’s mental condition at the time of the incident was so severely impaired that he was incapable of controlling his actions.
The defence also maintained that he could have qualified for a verdict of not guilty by reason of insanity if the matter had gone to full trial.
Judge Behan criticised what she described as serious failures within Ireland’s mental healthcare system, stating that the death could “arguably have been prevented.”
She further condemned the “unforgivable failures” in psychiatric care and support services, noting that a treatment appointment for Ogbo arrived by post two days after the killing.
In sentencing, the court considered Ogbo’s early guilty plea, lack of previous convictions and support from family members.
He was sentenced to five years imprisonment, with the final 18 months suspended.
The sentence was backdated to February 27, 2025, when he was first remanded in custody.
The court also ordered that Ogbo must continue engaging with mental health and probation services after his release from prison.
