A tragic murder-suicide case has rocked Dublin after 12-year-old Oisín Reddin was found dead from asphyxiation, an inquest has revealed. The boy’s body was discovered in his Clondalkin home on January 8 alongside the body of his father, Wayne O’Reilly, 48, who died from suspected self-inflicted injuries.
Terrifying Discovery Raises Welfare Concerns
Oisín’s body was found in a bedroom at Lindisfarne Grove, while his father’s body was located earlier in Cherry Orchard Drive, Ballyfermot. O’Reilly, who reportedly struggled with mental health issues, had a history of threats to harm himself and his son, though no charges were brought.
Oisín’s mother, Pamela Reddin, formally identified his body at Dublin City Mortuary. Garda Lisa Sexton escorted Pamela and Oisín’s grandmother to the mortuary the day after the discovery.
Coroner Clare Keane confirmed: “The cause of the boy’s death was external obstruction of the airway.” She also offered condolences to Pamela and Oisín’s family, saying, “I am so sorry for your loss.”
Ongoing Investigation and Welfare Review

An inquest has been adjourned until September 29 as authorities continue to investigate the circumstances surrounding Oisín’s death. Inspector Paul Mayock requested time to review the postmortem report and Garda findings.
It was revealed that Oisín was known to Tusla, the Child and Family Agency, though he was not in state care. The boy and his father had gone missing last October, triggering a Garda alert before they were found safe in a Limerick hotel two days later.

Tusla had implemented a safety plan allowing Oisín to live under the supervision of his father and extended family. Following this tragedy, the National Review Panel is conducting an independent review of the case to scrutinise welfare arrangements and lessons to be learned.
Background: Troubled Family History
- Wayne O’Reilly was previously arrested multiple times under the Mental Health Act.
- He allegedly sent threatening texts against himself and Oisín, raising serious concerns.
- Despite these warnings, no charges were filed, and Oisín remained with his father under a safety plan.
This heartbreaking case highlights ongoing challenges in protecting vulnerable children amid mental health crises. Authorities vow to continue their investigation and ensure thorough reviews are carried out.
