Respectfully, we don't know what TA's MO is. Really, all that we know about her comes from these murders. But based on what we do know, I would argue that she definitely shows signs of being sadistic, and torture very clearly suits her, in purchasing not one, but five stun guns, so each of the murderers would have one, after googling which stun gun delivers the most pain. Probable bludgeoning of the victims is certainly sadistic too. And as far as being in a hurry, bc she had to pick up her grandkids, she knew where they were, and many believe that her babysitters may have known where she was. I doubt there was a designated time for her to pick them up, or that they would have been tossed out if there was, and she missed the deadline. Lastly, she apparently convinced four people to help kill 2 women that they had no connections with. I don't see how someone can draw a line by agreeing to kill someone that they don't even know, because someone asks them to, but they will only do it humanely. Apparently, neither of the women were shot, so their deaths were very likely not immediate, nor even necessarily quick. JMO
