Again, you focus on the wrong aspect of the case. Which happened first, gun shot or stab wound, is meaningless to whether this was Murder I. Everything she did prior to entering the states of AZ indicates a pre-planned anonymous trip to Travis' appartment. The killing blow was with a knife to the neck in the bedroom/bathroom hallway after she had stabbed him several times. When she shot him does not matter. She had several opportunities to exit his house without cutting his throat and killing him, but she did not take that option. She made a decision to cut his throat knowing it would end his life. He was face down in the entrance to his bedroom when his throat was cut. She was not under him, so she had to be standing over him from behind. He was no longer a threat, so self-defense is gone when she delivers the killing blow no matter which version you believe (any of her multiple versions, the State's, or any of the one's we have come up with). How the attack started does not matter anymore. Even her version if it is true does not save her from Muder I as she was not fighting for her life when she delivered the killing wound.
True but the title of this thread is sequence of events. We are trying to put the puzzle together with the evidence given.
