Wasn't it mentioned that one of the victims (presumably Kaylee) had already moved out and was only "back in town" to show others her new car?

Not sure where she was from or where she was staying before coming back that day, but I'm wondering if something could have happened away from Moscow, only for someone to follow her back to Moscow that day and complete the attack?

I'm wondering if LE is also looking for information from wherever she was at before returning to Moscow. I wonder if there's highway footage of someone leaving town shortly after her and then returning to town early-am on the 13th at a time that would match up with the driving distance? Just a thought. 🤔
