A 39-year-old Nigerian man living in Ireland has been sentenced to three and a half years in prison for killing his grandmother. Brian Ogbo pleaded guilty to manslaughter after the death of Stella Nnadi, 82, at their home in County Cork.
Ogbo arrived in Ireland from Nigeria just two months before the fatal incident in February. He came to reunite with his mother, Ruby Ogbo, and his grandmother after years of separation.
The Cork Circuit Criminal Court heard that Ogbo had suffered from schizophrenia since 2017. When he moved to Ireland in December 2024, he missed two scheduled anti-psychotic injections due to delays accessing mental health services.
His mother, a trained social worker, tried repeatedly to secure psychiatric treatment for her son. Her efforts to get him proper medication proved unsuccessful.
Judge Sinead Behan noted that Ogbo was "clearly in the throes of a psychotic episode" when the attack occurred. Detective Tom Delaney testified that the defendant had spent hours pacing throughout the house before the violence erupted.
According to Delaney, Ogbo damaged parts of the kitchen and consumed all food in the home. Tensions mounted when Ruby confronted him about his behaviour and threatened to take away his phone.
She removed the internet router and tried to leave the house. Ogbo allegedly chased her with scissors in hand.
The detective told the court that Ogbo pushed his mother to the ground in the kitchen. He punched her repeatedly while she lay on the floor.
His grandmother, fearing for her life, had locked herself in the bathroom upstairs. Ogbo began shouting at her to open the door.
"Oh my God, Oh my God," the elderly woman cried out, Delaney recounted to the court. Ruby managed to escape the house and alerted neighbours about her son's threats.
Ogbo forced open the bathroom door and dragged his grandmother downstairs. He pushed her outside the house, but she managed to reach a neighbour's home with her daughter.
Two days later, Stella Nnadi's condition worsened and she was admitted to hospital. A medical scan revealed bleeding on the brain, and she died on February 25, 2025.
Postmortem findings showed she died from blunt force trauma to the head. The injuries occurred when she was forced down the stairs during the attack.
Defence counsel Jane Hyland described the incident as tragic for both the family and Ogbo. She argued that his mental state was so severely compromised he couldn't control his actions.
According to Hyland, Ogbo had maintained a close bond with his grandmother throughout his life. She suggested he might have received a not guilty verdict if the case had proceeded to full trial.
Judge Behan strongly criticized Ireland's mental health system during sentencing. She stated the death could "arguably have been prevented" with better care.
She condemned what she called "unforgivable failures" in psychiatric services and support. A treatment appointment for Ogbo arrived too late to prevent the tragedy.
