Twenty-two-year-old Trevor Deely vanished while walking through Dublin after a work Christmas party. CCTV captured his final known movements, but no confirmed trace of him has been found and Gardaí continue to seek information.
Trevor Deely was 22 and working in information technology in Dublin when he disappeared in the early hours of December 8, 2000. He had attended a work Christmas party and later returned briefly to his office before setting out on foot toward his home.
Gardaí state that Trevor returned to the Bank of Ireland Asset Management offices to collect an umbrella. CCTV showed him at the building and later captured him passing the Bank of Ireland ATM on Haddington Road at approximately 4:14 a.m. That is the last confirmed sighting released by investigators.
An unidentified man was recorded outside Trevor's workplace earlier that morning. Garda appeals have sought information about that man and about anyone who may have seen Trevor after he left the office.
The disappearance triggered extensive searches, witness inquiries and repeated public appeals. Investigators examined waterways, CCTV, phone information and multiple theories. A major search in the Chapelizod area in 2017 did not recover Trevor or evidence that resolved the case.
Some public theories have suggested accidental death, criminal involvement or homicide. None has produced a court finding or a confirmed account of what happened. In particular, people visible in CCTV should not be treated as perpetrators merely because investigators sought to identify or interview them.
Gardaí continued public appeals years after the disappearance and maintain a dedicated missing-person entry for Trevor. Official material asks anyone with information to contact Pearse Street Garda Station.
Reporting in 2025 noted that the case had not been upgraded to a murder investigation after a review of cold cases. That distinction matters: foul play has been considered as a possibility, but the official status remains an unresolved missing-person investigation unless new evidence establishes otherwise.
Investigators still do not know where Trevor went after the final CCTV sighting, whether he met anyone, whether he entered water, or whether another person caused his disappearance. No body has been recovered and no person has been convicted of an offense connected to his disappearance.

The absence of an answer has generated many theories. This archive does not identify any person as responsible unless reliable evidence or a court judgment establishes that responsibility.
