This testimony is just white noise at this point. Filibuster is right.
Instead I checked out
bermstalker's timeline.
The timeline helped shape my understanding of their relationship. Travis never really stopped dating or seeing other women, I don't think they ever really were a comitted couple in his mind. Jodi might have wanted that but was seeing other people and looking for opportunities with other men.
What if her motivation for the killing was recognition? What if she wanted everyone (the Mormons, Travis's other girls, Prepaid Legal people, The Hughes) to know that she really was his girlfriend? The "long email" from May 16, 2008 lays out her motive for the killing.
Now the trip to Cancun with The Hugheses. Travis can't take her, I think mainly because The Hugheses will hold it against him which would harm his professional life (already suffering) and social life in the church. Yes, Jodi is jealous of Mimi, but she has tolerated other women in the past. She was not violent to Mimi or Lisa, her violence was directed at Travis. By killing him, she vented her rage at never being recognized as his girlfriend. By killing him, she showed everyone that she possessed him and now he must admit that she was/is his girlfriend.
She has gotten her wish. Now it's all over the news that Travis's "girlfriend" or "ex-girlfriend" killed him. It's a shorter headline than overly attached psycho fuckbuddy.
