Nothing new on this case, apparently. However, I must have overlooked the obituary a few weeks ago stating that she "died by accident" while on a "private retreat" and walking around the lake (which she DID have a connection with -she'd visited it as a child).
I guess this is certainly a possibility, but what could the accident have been? Slipped, caught off-balance, etc. and fell into the lake? There are three possibilities that I can think of which would prevent her from simply getting back out again (and she was a good swimmer, now we know). Those would be that either she was walking along a part of the lake that had a long, "unclimb-able" drop to the water, or that she'd hit her head on the way down, or that she suffered some other medical problem which incapacitated her to a point such that she wasn't able to swim, climb, etc.
I think the first would be something we would have heard of as a possibility, should LE/family considered it possible. The second possibility, that she hit her head, could certainly have been something that wouldn't necessarily have been noted before an autopsy, although I'd think it more likely than not that there would be some indication of such.
Now, the third possibility: She had a "medical event" that precluded her from swimming, getting back out of the lake. This could have simply been a freak event, such as a heart attack, stroke, etc. Or, did I read somewhere that she had asthma? And, if not, doesn't everybody? Okay, hyperbole here, but so many, many people have asthma these days. Could she have fallen and the cold water triggered a severe asthma attack, rendering her unable to swim? Actually, very cold water can have a stunning effect on even a "normal" persons breathing capacity ("cold water shock").
Just thinking here, but I wonder if anyone else has any ideas?
And another note on the car keys: Apparently, they were placed on the top of the front tire, therefore, were deliberately placed. So, why would she do this? There are only two reasons that I can think of: She didn't want to carry them with her (Why not? No jacket pocket? Wouldn't she have been wearing a jacket? Hmmm.) or, she left them for someone else to find, meaning that she knew she would not be returning. Any thoughts or other ideas on this?
RIP Raffaella.
