You may be right. But not if she died within minutes of the head injury. It's the same argument being used about the ligature, that there was no head swelling b/c she died after being choked. Same argument here. If the blow killed her, no swelling.
I agree that I don't think it was a bat now. That should have left plenty of external bleeding and clearly didn't...no laceration.
LOL...this is never ending, isn't it...
I should have said, I agree IN that I don't think it was a bat, now.
