I found an article about JBR in an online version of a magazine called Inside Crimes.
It stated that the theory put forth here about accidental killing of JBR by brother then the staged strangulation is not prosecutable as murder. I'll post a link. Could this be the true quagmire that ties the hands of prosecutors? Being able to prove it was murder.

I've been a big fan of that article for quite some time, Cathy. And you may be right.
