To your number 2 question, the theory was that Casey lied, partied, was promiscuous, etc. because Daddy & bro molested her and it was the big lie in the family so, according to the defense, it’s perfectly understandable why she lied and acted as she did for those 31 days...total crap IMO!
You’re right.
But none of that would matter if the baby drowned herself in the pool - would it?
IMHO the judge made a mistake when he let the defense introduce the accusation of incest without demanding the defense to substantiate the claim.
In allowing the defense to keep pounding the incest accusation he handed them a gift that probably led to the not guilty verdict.
The defense worked the whole trial to cast suspicion on the father and it obviously worked. We are already hearing jurors say they did not trust the father - that they think he was hiding something.
For jurors who were looking for an out or didn’t want to deal with sending a young woman to prison for life, the defense attorney gave them something to hang their hats on.
Now they can pretend they had a valid reason to duck the guilty verdict.
I think the jurors will be plagued by their bad decisions and sorry conduct the rest of their lives. Nightmares will be the least of it.
