Based on my experience dealing with an actual scuba fatality, the facts rarely all add up nicely.
The woman's buddy in my case swore that she had released the victim's weightbelt. I know for a fact that her weight belt was still around here and I released it when they were attempting to pull her up onto the dock. I don't know why the buddy swore she had done that, but she might have pulled out a BCD strap and thought that was the victim's weightbelt.
On the other hand I thought there was no blood at all, but multiple of my buddies have mentioned a whole lot of blood. I'm probably misremembering there based on the M.E.s result that death was due to lung barotrauma and probably just because blood doesn't freak me out at all, so I probably just never noticed it (odd that I was right in front of her, unclipping her drysuit hose and releasing her weightbelt as she was dragged out of the water and I don't recall a spot of blood and other people describe the front of her drysuit as being bloody at that time).
I also had the buddy tell me that the accident occured at 10 feet of depth and that they had made a safe ascent up to that point. I heard the buddy repeat that over and over to multiple different rescuers. The buddy still wound up being put on O2 with several people flat-out assuming that the buddy was going to be bent and not bothering to listen what was clearly stated over and over that the accident occured at a depth of 10 feet. People's preconcieved notions of the accident, however, led them to not listen to that and assume the accident occurred at more significant depth and that the dive buddy could be bent.
So you are all trying to take media reports and court documents and try to make 2+2 add up to 4 when I don't think that is remotely possible.
