I guess it's time to stop stalking and start talking! This is my first post, so like everyone else says, forgive me if I do this wrong or if any of this has already been covered!
I've been pretty obsessed with this case ever since I stumbled upon it a while back. I have spent LONG hours googling and looking through millions of pictures and profiles of missing persons in countries all over the world and all through America and Canada. It seems as though the obvious ones have been ruled out and based off of the surprisingly large number of websites looking for "lyle's" true identity, there is certainly no shortage of people doing their own research on him. The biggest question for me is why no one is "looking" for him. My only thought is that he tied up each and every loose end he had. I can almost guarantee he quit his job amicably, giving notice well in advance as well as probably telling everyone he was associated with that he would be moving and doing the same for whatever living arrangements he had up until September, making sure that no one had any reason to need to contact him in the future. Another thing I'm starting to realize in researching suicide, especially by hanging, is that for him to look that lifelike and not grotesque after he was finished and especially in the hours afterwards, he had to have an extensive knowledge about the whole concept. I came across a website that basically outlines exactly what he did, written many years ago (based off of the years in the sited statistics) that I am convinced he read. I'll post a screenshot if I can figure out how. That being said, I also wonder if he was in the medical profession. I know people have suggested that before, but much of that was based off of the handwriting, which I personally discounted, only because I write almost identical to him and have absolutely no medical experience whatsoever. Anyway, I realize I have really not said anything of any real value, just a couple of opinions,but some of my other theories are so outlandish that I'm almost embarrassed to post them!
