Thanks for the compliment. Are you in the medical profession? I can't help but ask with a hat called ICU.
By all accounts, and this is a fact, the body was found wrapped in a blanket. Her own father recalls it as "papoose-like". So someone took the time to wrap her up after killing her. Yes, this was a brutal murder. I think the staging was not meant to be cold, jut to point away from the member of the family that killed her. There are so many theories floating around. If Patsy or John killed her, then I think it was an accident and was covered up, not to be cold, just to cover it up to look like an intruder. If Burke killed her (a strong theory for me) then I have no problem with the scenario that he was enraged with his sister and the parents covered it up.
All my theories involve a family member. I have no doubt that her parents loved her, but I truly believe something went horribly wrong that night and they felt they had to cover it up for their only remaining child together. oops, did I say that out loud?
