I have been going back and forth between targeted and not targeted and still have not reached a conclusion. But what points me to the not targeted side are a few things. If this was targeted, SP would have had to have known she was going to be alone and not have brought her child with her. Otherwise, would we be looking at 2 murders and not just one, IF she had brought the child along like she had done in the past?? OR, if she had showed up with her child, would SP have gave up the plan and then tried to slip back out of the church without harming her and risked being seen by her/child and having cops called? With her bringing the child before to these workouts, it just don't make sense to me that it was planned, UNLESS he/she KNEW that she would be alone. And for me, only way to have known that, was thru her/husband directly telling the SP.
Second thing that makes me think not targeted is: Why inside the church?? Obviously I don't know the layout of the EXTERIOR of the church but if I'm there just to kill my target, why go inside the church at all? I could wait until she gets there, and surely know that she's got to get equipment out of her vehicle to take inside the church since she's the instructor, and just ambush her then and there in the parking lot. Why go inside and put myself in a position to be "out of place" and possible alert her to my presence and give her a chance to get away or alert authorities before I could get to her. Especially if I don't know if she's alone or not. If I'm outside hiding, that takes all those possibilities out of play. If she shows up with her child, I can just sneak away and try later.
I'm leaning toward not targeted.
