This is what gets me. From day one, that simple question hasn't been answered satisfactorily or corroborated. Rightly so for investigative purposes. Wrongly so for the residents of Midlothian and other interested parties. Murder investigations tend to cut both ways. LE isn't going to hand over the goodies: the autopsy, the CCTV we haven't seen, their suspect list, a full report of their progress. All of it handicaps complete and accurate analysis.
The fact is SP murdered someone. Whether he bashed her heart and head with a claw hammer, or raked her heart and brain out of her body with a prybar, or he blew two holes in her, MB was murdered. The clues available to us are few: Sp's odd attire, behavior on CCTV, physical oddities. That's it. Everything else is an intuitive guess based on our life's experience, familiarity with some criminal behaviors and our burning desire to see justice done...there are motherless children. We want to help.
If anything comes of these kinds of murders, let's hope they convey the message that anywhere the public gathers or money changes hands, the best CCTV equipment must be available and in good working order. This blurry, stop motion stuff has got to go. Cheaping out on as important a security measure as cameras is indicative of how little proprietors and administrators value human life. Why bother if you're going to hand over a series of smudges to LE when a service person or innocent visitor is blown away? Lives are more important than the few pennies saved by not upgrading or maintaining surveillance.
I can't wait for this idiot to be captured.
