Gardaí Examine New Information in Philip Cairns Disappearance
Gardaí are examining new pieces of information concerning the disappearance of 13-year-old schoolboy Philip Cairns, who went missing in Dublin four decades ago. On October 23, 1986, the teenager left his family home on Ballyroan Road to return to Coláiste Éanna in Rathfarnham after lunch, but never arrived, marking the beginning of one of Ireland’s most high-profile unsolved cases.
That afternoon, Philip left the school at 12:50 p.m. to walk the short distance home, according to RTÉ. He gathered his schoolbag and left again at 1:30 p.m., which was the last time his family saw him. Six days later, investigators recovered his schoolbag in a laneway linking Ann Devlin Road and Ann Devlin Drive, though several of his books were missing. At the time of his disappearance, he stood 5 feet 2 inches tall with short black hair, and wore his school uniform consisting of a grey jacket with black shoulder corners, grey trousers, a grey shirt, and a school pullover.
Four Decades of Investigation and New Leads
Over the past 40 years, Gardaí have pursued more than 1,600 lines of inquiry, maintaining regular contact with the Cairns family. While Gardaí receive public information on a regular basis, recent media attention has brought the case back into public discussion and generated fresh leads. A Garda spokesperson stated that the newly submitted information is currently being examined and assessed to determine its evidential value.
Investigators are particularly appealing to individuals who may have been too young at the time to come forward, or who withheld information regarding Philip or his schoolbag due to circumstances that have since changed. The force has assured the public that anyone stepping forward now will be treated sensitively and discreetly.
The Impact of Time on the Cairns Family
The milestone anniversary coincides with the passing of Philip’s mother, Alice Cairns, who died in November of last year. In a 2016 interview with RTÉ Radio, she expressed that she had only begun to accept in the final years of her life—following the death of her husband, Philip—that her son would not return, having spent decades holding onto hope.

Authorities have urged anyone with knowledge of the case to contact Rathfarnham Garda Station at 01 666 6500, the Garda Confidential Line at 1800 666 111, or any local Garda station.
