I'll bet the witnesses--including ones who are hiding-- are terrified of Jodi.
These murderers do go free--we have all seen that with OJ and CA. Imagine being a person who testified against one of these two and then they're out on the street.
I think Travis was depressed because he was hitting 30, which is the end of the "normal" marriage phase for a Mormon male. At 31, he would be forced to leave the singles ward and would be going to church among all the families and a few single ladies. Family wards have Family Home Evening with their families--so no more cookies and status as a prime eligible bachelor would change. He would be one the ward members would ask about, "Why isn't a handsome, successful guy like that married?"
He's writing a book about success. He doesn't want to be seen as a failure and I think he was pretty much a straight and narrow guy until he met seductress Jodi Arias. Now this is just my opinion so don't get all upset, but I think he told Jodi he was going to go to the bishop and get his life straightened out. This would mean confession and naming her. He was effectively nullifying her plan of blackmail and his action would finger her and generate a meeting for her with her bishop.
She saw herself as losing everything if she lost Travis--her place at the winners table at PPL and her status as a Mormon convert. She had given up her relationship with Daryll for Travis and along with it the house which was going to launch her into the middle class. Now she has nothing and is back living with her grandmother. She spent all that time climbing the ladder of success via him and he "owed" her for these losses and so she was entitled to his car. All he had to say to lose his life was, "I'm calling the police."
Everything she did was for herself. She may have killed him to keep herself out of jail.
I personally hope she gets the DP. I know from my son that these famous killers enjoy celebrity in prison and have romance, attention and a whole prison culture at their feet. It makes me sick to think about her getting her attention-





hunger fed after so brutally taking the life of a decent guy she seduced and then trying to paint him as abusive and a pedophile with her lies.
