You are looking at this through the eyes of a normal person. She is a stalker, deciding days ahead that if she couldn't have his lifestyle, no one would. She took the gun and the knife because she wanted to seduce him then kill him. She knew his habits. Get him relaxed, then in the shower, then as he turns in the shower, stabs him in the heart. He comes out stumbling, coughs up blood in the sink, according to the ME, she continues stabbing him in his back, he makes his way to the hallway losing blood and collapses. She then turns him over slits his throat from ear to ear and drags him back to the shower. Then she puts a bullet in his head for satisfaction. That's all it was. Satisfaction that she could stalk him, slaughter him, shower his dead body and hers, try to clean the crime scene, deletes the photos and puts the camera in the wash with Clorox. The card in the camera survived. She isn't sad he is gone. She is quite proud of her handiwork. She is lying. There was never a struggle for her. Just him struggling to live. He couldn't even fight back. If she isn't found guilty of premeditated murder there will never be any justice.
If this were self defense, whether by stabbing or shooting, once he was down, you or I would run out the door, go to a neighbor, scream for help, get the police. None of that happened.
Travis had no history of stalking. She does. He has no history of pedophilia.
