Everything that possibly could have gone wrong, in order to implicate an innocent KA, would had to have gone wrong, in order for her not to be guilty of this murder. Someone would have had to get her Jeep and drive around while her phone was in the Jeep, although we have seen texts from her at her supposed appointment, during that time frame. They would have had to have gotten into her house, gotten her locked gun and ammo. Then they would have had to committed the murder while KA was otherwise still unaccounted for, spread her DNA around, then returned the Jeep, gun and phone to her without her having missed or reported any of those things.

Sounds plausible to me....
