First time poster, long time member. Here is what I think happened :
Pic @ 5 :30pm of Travis in the shower, looks surprised & scared
Next pic he is sitting down in the shower. I believe in this pic he was startled, trying to get out of the shower & he slips on the water & his fallen position gives her a perfect stab. This is where I believe she stabbed him in the heart, hitting the pericardial sac & supervior vena cava, he manages to get up, staggers to the sink not to look at himself but simply for support, he coughs, thus the blood spatter at the sink. She is behind him stabbing him in the back. He turns to flee, staggers down the hallway, (higher blood stains) he's leaning on the wall, he falls, rolls on back, thus defensive wounds to his feet, he manages again to get up on all fours (her statement he says "I can't feel my legs") , he gets to bedroom/hallway threshold, she straddles him & slits his throat. Much blood here. She drags him back to the shower, he begins convulsing & the animal who is Jodi Arias shoots him in the head, using his tassle pillow as a silencer. He is dead now, no blood along cerebral/sinus bullet track as he has lost all his blood volume. She showers at this point, then gets him him the shower. All the while the water (shower) was running, thus the high water stains on the storage boxes. She throws the camera in with the bedding, probably lost track of it as her time to get out of there was running out as the roommates were due home, washes the camera & gets the heck out of there.
This woman disgusts me. Here total disregard for the justice system, her lack of respect to Mr. Martinez, & the fact that she has never shown remorse or said "I'm sorry" to Travis' family makes me sick. Death penalty or LIP, neither matters to me as long as she gets to suffer knowing what she did for the rest of her miserable life.
It doesn't matter to the case what sequence his death occurred, both are considered cruel for premeditated murder but this is my two cents. She is evil through & through.
