I just wanted to say that the cause of death was noted already. The cause of death was blunt force trauma to the head - by the hammer. This was pointed out by TLM, and by the Crown already, and will be confirmed by the ME at some point, I'm sure. Thats my :twocents: worth - that the ME will testify to that. We don't know that yet for a fact. But we DO know that the Crown and TLM have both stated that the cause of death was hammer blows to the poor girl's head.
In addition, I wanted to point out that we've already heard that (sadly!) Tori was ALIVE when her rib was fractured, and liver lacerated. The ME would know this because of the processes a living body goes through when it sustains a fracture (it has to do with the process of inflamation). There would be tell tale signs in the organs that had to do with oxygenation, chemicals released by the body etc - things that would NOT have taken place if the body were already deceased when the rib was fractured.
You can read more about the forensics behind how they would have determined if she were alive or already dead when the rib fracture and liver laceration happened HERE:
