What do we think about the "we didn't kill her, but..."? So, she died, but EB claims that AB did something horrific afterwards - like what - dismemberment, I assume?
So, what in her mind would be "we didn't kill her"? Frankly, I could see someone at this level saying in her head, "We only beat her, and then she died, so we didn't kill her, really." (As if that wasn't murder.)
My theory is that someone hit her, she got sick and wasn't taken to hospital, and died later from it, and then AB dismembered her to hide the body.
What's your take on why she would claim they didn't kill her, and yet she died?
(Although, in her mind, she might think it is "cool" to have a husband that did awful things to dead bodies, so the letter might all be manure, AFAIK.)
