His family and friends are delivering leaflets throughout the city in the hopes that it will trigger somebody's memory.
"Look, what I'm saying to him is - if you make a phone call, just make a phone call to his mother, she's waiting at home, and all we want to know as a family is that he's safe," said Tim's father, Stephen.
"And look, if he wants to stay in Dublin, that's fine, but just make contact."
