With all the eyes that have been all over this case from day 1, I find it incredibly difficult to believe that IF all three men were involved, not a single LE officer or agent, have been able to tie that together in almost 6 years. No one, but this mysterious unnamed DM source, that is. My how handy for that person, especially if they can somehow benefit from it, like it maybe they wrote a book about it, or something.
Probably just a huge coincidence though.
Sure I know, folks have their opinions of bumbling LE along the lines of Barney Fife or the Keystone Cops (or worse) but that's one heck of a large brush to paint ALL of them with.
