I’m not saying 3 women are frequently killed by an angry baby-daddy. I’m saying that it’s a theory that makes a lot of sense to me in this particular case.
One of the big questions in this case is motive, and it’s frequently mentioned that one of the women may have been the target with the other two as collateral damage. Well, if Suzie was indeed pg (upset stomach, needing a friend etc), that could have pushed the already-angry ex over the edge. Double motive - solve both his criminal & personal problem birds with one stone. It’s a known fact that women are at highest risk for DV- related homicides when pg and/or trying to leave. And the theory that she may have been targeted due to the criminal case has been around since day one. So, it fits.
Another big discussion is that the “amateur “ criminal couldn’t pull this off alone. Enter the fresh-from-prison, experienced felon family friend and you’ve got that question answered, as well.
