In my opinion, this is a very solemn and sensible post.
All we have at the moment is conjecture, because we are not privy to all the information that is known, or the information that will be discovered through an investigation.
I believe your implication is well-founded. It strikes me as highly implausible that the professional sensitivity and judiciousness shown by the efforts to shield Kiely would be undone in such a careless manner.
Although I choose not to examine that picture thoroughly, IMO it is anything but her hand. Maybe it's the headrest, maybe it's a reflection of something outside of our field of view, maybe it's a shard of glass, maybe something else.
To be gruesome, I don't know much about forensics but I doubt after two weeks in the water, Kiely would still be able to grip something at all. I don't know how two weeks in the water affects rigor mortis but I know what I believe happens.
It's just too upsetting, so I'm going to relieve myself of this part of the discussion, but I did want to thank you for the wide range picture and the context you've provided.
