Gardaí are examining new pieces of information concerning the disappearance of Philip Cairns, who went missing in Dublin 40 years ago. The 13-year-old schoolboy vanished on October 23, 1986, as he walked from his family home on Ballyroan Road back to Coláiste Éanna in Rathfarnham.
The Disappearance on Ballyroan Road
Philip Cairns left Coláiste Éanna at 12:50 p.m. on October 23, 1986, to make the short journey to his family home. He later collected his bag and left to return to afternoon lessons, but he never arrived and was never seen again. Six days after he vanished, his schoolbag was discovered in a laneway linking Ann Devlin Road and Ann Devlin Drive near the school. Some of Philip’s books were missing from the bag when it was recovered.
When last seen, the 13-year-old was 5.2 feet tall with short black hair. He was wearing his school uniform, which consisted of a grey jacket with black shoulder corners, grey school trousers, grey shirt, and school pullover. Over the past four decades, gardaí have followed more than 1,600 lines of inquiry in one of Ireland’s most high-profile unsolved cases.

Recent Media Attention Brings New Information

A Garda spokesperson appealed to the public, stating that anyone with information should not assume authorities already possess it or that the details are irrelevant. Investigators are specifically appealing to individuals who were young at the time and unable to come forward previously, but who may now be able to assist with changing circumstances and the passage of time. Authorities have reassured anyone stepping forward that they will be treated sensitively and discreetly.
