I have a question--wouldn't Ayla's blood having been found in the basement suggest that Ayla has met harm? Of course, I understand that there could be an explanation, but isn't the presence of blood at least a suggestion of harm? Maybe I misunderstood your post. I apologize if I did.
In some ways, it would. The thing is that LE won't confirm the amount and/or location of the blood that was found. It could have been the 4 drops that people have said, or it could have been way more than that.
I've wondered if the blood evidence could possibly be less significant than most of us believe. An innocent explanation is not outside the realm of possibility, because we don't know the circumstances.
JMO and you didn't misunderstand me!
