I know that is a popular theory, but wouldn't doing that just bring more attention to the area? The entire rest of the staging seems to be hiding evidence of the SA (cleaning, redressing her body, the RN to point away from the sexual motive etc).
I just had this conversation with an IDI elsewhere, Annapurna. And what you say about trying to "hide" it just convinces me that the stagers were trying to cover as many bases as possible. As in, "well, we hope they don't look, but if they do, this will explain it."
It might also suggest something I've said for a while: whoever did it was immediately disgusted by it.
Then again, who says it has to make sense?
Do we know as a conclusive fact that the "splinter" (Steve Thomas) or "birefringent material" (Kolar) or "cellulose" (icr who said that) is a part of the paint brush? Or is that still up for debate? It's still possible it was secondary transfer of course, but if it was conclusively linked it would go a long way in how likely I find that theory.
Good point. It just makes sense to me that it was the paintbrush handle because that would allow them to do it without touching her. Seems to be a lot of that.
