Allegedly...
Whether it be the shooter or the person who hired the shooter, someone did not want the Barraza’s to make the Orlando trip? But, then they would have known about the garage sale? Only a small circle of people knew about the garage sale. Of course, it is possible neighbors saw the signs go up.
The killer appeared adamant that S not be present and waited until S was out of the way before shooting Liz.
We know that the killer drove back by the crime scene- did the killer hear sirens, even after shooting off those four (4) rounds of deafening gunshots! Did they have no other choice but to turn around and drive back by the crime scene?
Speculation: Did an earplug drop out of the killer's ear(s)
Definitively, the killer’s only intention was to kill Liz? It wasn’t a robbery, a mistaken identity, road rage or neighborhood rage of some sort or anything else? It looked very personal.
It looked so personal. I'm so curious the connection between killer and person that contracted the killer. The killer made it look personal... aggressively walked up very quickly toward Liz with purpose. But, what if the killer is actually the one that wanted Liz dead, and didn't hire anyone? Wanted to kill Liz themselves? It makes sense to me. Their body language spoke it!
Did Liz do something to someone, or did someone want Liz out of the way for whatever reason, or what would the motive be? Motive would lead to the killer… I am sure of it.
Who benefits most from the death? Number one question with LE, right?
Someone knows something, and probably dont realize their information is important.
My thoughts, only and topped off with a little spitballing
