You may be on to something....Put your heads together.
66, can you ad any facts?
I'll have to read what was said - the gruesome knowledge statement had been discounted a few days ago, by someone in Keenan's office, maybe Nagel.
Since the coroner didn't even know about the head blow until he peeled back her scalp, the only thing Karr could know, if he did the crime, is the truth about the actual weapon used which didn't break the skin.
If he says a fireplace poker or something similar, I'll comment.
