Since 2000 many theories have emerged about what had happened to Trevor. Did he fall into the canal close by. Did he change his name and jet off to South America to get away from Ireland and start over. I remember being very vocal in my office at the time of his vanishing. During the period of 2000, we had seen many young women disappear in the 90's including Jo Jo Dullard, Fiona Pender, Deirdre Jacob and Annie McCarrick and to be fair it had crossed my mind did one of these missing women have a similar experience connected to Trevor.
My gut feeling was that the man seen talking to Trevor outside the Bank Of Ireland on the night of his disappearance is the man responsible for Trevor's vanishing. My theory is that man was collecting a debt from Trevor for something that Trevor had acquired from that man or associates of that individual. The man turned up outside that building because he must have known Trevor worked there and was asking him do you have my money. The boss is getting upset and needs his cash. Trevor didn't have the means at that time to repay the man and after a few warnings had got impatient and decided to deal with Trevor in a more aggressive way.
This theory by the way is pure speculation but having watched the evidence on TV documentaries, having seen the guy in the grainy image on CCTV and taking into account that Trevor just vanished, the only reasonable conclusion is that Trevor met his end in a very unpleasant manner. The area where he vanished was crawling with Pimps, Prostitutes and drug dealers. I also remember cocaine was rampant and that many people were taking it. The drug has to come from somewhere and someone has to pay for it. I am not suggesting Trevor had a drug habit but it is a theory that must have been examined by Gardai. In the last few hours Gardai have been digging up an area of land in Chapelizod, West Dublin and following a tip off from an individual who said that Trevor had an interaction with top Dublin Criminal who was operating in that locality at the time.
To this day I still see photos of Trevor attached to lamp posts on Haddington Rd and Baggot St. I wish Trevor's family have closure soon and that this case is not a cold case anymore and that it is eventually solved.
