"This guy is not to be found" - Trevor Deely

In the dead of a stormy December night, 22-year-old IT worker Trevor Deely vanished from a rain-soaked walk home after a company Christmas party — last seen on CCTV, umbrella in hand, forever lost in Dublin’s empty streets. Despite decades of police investigations, enhanced video footage, searches of canals and secluded areas, and a €100,000 reward, not a single clue has definitively explained what happened to him. Was he the victim of a stranger ambush by the mysterious “man in black” seen on camera — or did he meet with a tragic accident in a canal nobody noticed amid the taxi strike and heavy rain that night? On this episode of The Last Clue, we retell what we do know — and examine our own haunting theories 25 years later.
