Nice post, @Sjöberg. Appreciate your posts. Not sure if it's considered official or if it is helpful; however, I've linked the parents' video below. BN is Liz's dad. If interested, please reference video at timestamp @10:57.I think this statement (parking in the garage) has never been accompanied with any kind of an official link. My family would also say stuff that I "always" do - while I might do these things on most days, it's rarely so black-and-white.
Why I find this statement fishy is that we have the doorbell footage of Liz going to Starbucks in the morning. And she goes to a car that is parked outside, not in the garage. And when she returns, she again parks outside, not in the garage.
Maybe she did park in the garage 95% of days. But we have video proof that she did not do that always. Moreover, the killer might be totally unaware of her parking habits 95% of the days if the killer drove by 2 AM and saw Liz's car parked outside.
MOO
@8:46 BN: The Orlando trip was one of several trips that they had planned and budgeted for because they really loved doing it.
@9:33 Beginning talks about the garage sale
@10:57 BN: So what Liz always did when she left the house was her car was in the garage - she would go out to the car, lock the door, set the alarm and then she’d start her car up. Lock the doors, open the garage door and back out.
The day of the garage sale. That abundance of caution led her to set the alarm in the house on instant trigger and leave the door from the garage into the house unlocked. I can only say this was in case she needed a quick retreat. That she knew if she could get to the door and pop it open the alarm would instantly go off.
