"(Kara) observed the defendant pull out a gun and shoot her father. As she fled from the house, (Kara) then saw the defendant turn and point his gun towards her mother."
Maybe you didn't see this part. She WATCHED him kill her parents. She saw them bleeding and dying. Then she stepped over them in her rush to join her beloved.
What if she willingly went to a bank and signed a contract to buy a house? Would it be legal? No. Why? Because we say that 14 year-olds aren't mature enough to make those decisions, willing or not.
And this contradicts the earlier, sibling reports, which stated that he went looking/calling for her after the shootings...!
