My Big Question: They did not have ANY idea about this suspect until 6 days ago, and I'm wondering: Do ALL law Enforcement collect DNA samples of their Force, and if not, why not?
Also, despite the officer saying that nothing in Michele's book led them to THIS man, it's clear that her book and ALL THE OTHER PUBLICITY, including possibly Websleuths, amped up the interest, the public curiosity and exposure and maybe even led to whatever it was that enabled them to zoom in on this man 6 days ago, before they took DNA from the discarded DNA piece.
I'm thinking it was the brilliant forensic drawing (sorry, forgot artist name, my apologies...someone fill in here). I think LE looked at that photo and ran some kind of reverse photo ID program against their own former employees in the entire six-county area for those period of time he was active, then Bingo.
