I just find it hard to believe that Katrina had been doing errands...and failed to complete them all at one time. Instead she completed part of them, went to the marital home, and left again at 9pm to complete more errands. Then she was planning to return to the marital home? For what purpose? After all, she still had to go to her own separate residence in Roscoe and go to work the next morning. Her family stated that they knew something was wrong when she failed to show up for work.
What errands are done after 9pm...especially if you have been out during the afternoon doing errands. And if she was picking up groceries or such, would she not return to her own separate residence instead of going back by the marital home? Lots of questions about all of this.....
