Without spending a lot of time on Wikipedia and looking at SSI statements I can't verify this, but I'm fairly sure that many years ago I worked with a murderer on the lam, who remained at large for a good twenty years till people recognized him from America's Most Wanted. He had been a white collar worker and was then a short order cook. His big asset was drabness. He did not stand out, he did not say much, and if you thought you might have seen him you could not say where or how. I think this sort of thing must be a lot harder to do now.
