Trevor left Buck Whaley's nightclub in Leeson Street after a Christmas party and entered his workplace nearby at Bank of Ireland Asset Management at 3.30am.
Trevor was a member of the IT department of the bank and when he arrived he was "drowned wet", said fellow staff member Karl Pender who was working overnight in IT. Trevor chatted with Karl, briefly logged onto his computer, then went for a coffee with Karl to the office canteen and chatted about the night's Christmas party. He picked up a big umbrella and left the building as the rain poured down.
Around 4am, Trevor called his close friend Glen Cullen and left a voice message telling him he was on his way home and he would talk to him tomorrow. He never reached his apartment. But as a result of an enhancement of images taken from the CCTV cameras gardai are now aware that a man was standing in the doorway of the office, possibly sheltering from heavy rain, as Mr Deely walked in shortly before 3.30am. Mr Deely is seen talking briefly to the man and then walked into the office.
The man is later shown walking across the road. CCTV footage later shows Mr Deely leaving the building and walking along Haddington Road, shortly before 4.15 am.
The footage contains an image of a man walking behind Mr Deely but it is not clear if this is the same man who had earlier been in the doorway.
