I think Jorge was in AA and Sarah hated it
This may not be a new observation but thought I’d mention. When he was found dead inside that suitcase was a vial of Valium prescribed to him. Valium is prescribed to those who are coming off alcohol as sudden alcohol withdrawal can be very dangerous. Of course spending time with Sarah would thwarted his attempt at sobriety Valium or not, which is why he had alcohol in his blood after death on that night
At the time he died he was on probation. A condition of his probation may have been that he seek help for alcohol use disorder. He was regularly attending probation. You may recall Sarah mentioning the probation officer in the interrogation and how his probation officer just loved her. Sarah said the probation officer had called her, I think Sarah actually called the probation officer - information seeking for the sake of control. In the interrogation she said that because of this “he changed!” and she acted happy about this. But I don’t think she was happy, she was resentful.
There is a video of Sarah - I think the 2nd of February - waking up Jorge accusing him of taking her keys. He said “I don’t know where your freakin keys are” and she said with contempt “so you’re not even going to curse now?” A few weeks after this he would be dead.
AA is often affiliated with Christian charities and if he was attending maybe he really was changing and embracing faith. Sarah had isolated him but now he was part of a community. I believe Jorge had mentioned Jesus in some text messages. I think his mother is a Christian I’m not sure how I know that. But he may have been embracing the faith he was brought up with..
Sobriety and community may have given Jorge the clarity to see that he needed to leave this relationship. When he started packing the suitcase to leave she brought out the baseball bat and suffocated him in his own suitcase.
If Jorge was changing this was intolerable for Sarah, as it reveals her own shortcomings and failures. If Jorge was getting better, she hated it and that’s what drove the violence she inflicted on him.
I’m speculating based on some of the things I’ve mentioned in this post. I’m rewatching the entire trial at the moment.
Edited for typo and to add another thought. Apologies if I’ve doubled up on any of the points I’ve made.
