I wrote about this in post #814, but I honestly think we are seeing a new kind of criminal--one that has existed in movies for awhile, but who has the mind and resources of a hacker. He identifies security flaws and is expert at exploiting them-- in other words, he's got an algorithm. His crime reminds me of other kinds of crimes (especially financial crimes, crimes in cryptocurrency, etc) that seem impossible to believe because they're so straightforward it makes them an elegant kind of genius. And leaves us scratching our heads.
He is doing the things he feels he needed to do and nothing else, IMO. He didn't need an automatic weapon (say what? bolt action?), he didn't need crazy decoys to get away (unless the cell phone deliberately left behind turns out to be one), and my feeling is (and this is MOO and I'm prepared to eat crow if I'm wrong) he doesn't think he needs to worry about having been seen, or leaving DNA, or whatnot. He doesn't view those as mistakes -- just as details he can ignore. I'd bet he at least *thinks* he's got a plan for that. I think he has help, and I think it comes from outside the country. If my hypothesis seems cinematic, it's because I think this crime and its solution are very deliberately cinematic.
If we have seen anything wild unfold over the past several years, it's that a private party can amass enough money that they can create a private space company with which NASA now must play ball. I believe this killer may have access to that kind of money and that breed of network, the kind where you can make anything happen, including making a killer vanish.
All MOO.
