It is the logical assumption.
Still waiting on tests and blood samples and crime scene evidence processing.
It’s been reported that Kalee and Jack had been together for 6 years. Kaylee was graduated this semester and moving to TEXAS for a tech job.
What about Jack? We don’t know much about him yet. Did Kaylee end the relationship before leaving for Texas permanently? Just a question I would wonder about since they called him so many times tight up to the window of death (3-4am). It’s strange IMO
