One of the reasons behind thinking this was not a targeted crime was that the burglar came out of the kitchen room at 3:50 am. Missy's classes did not start until 5 am. The early bird campers started at 4:30am. If it was targeted why arrive so early? In addition, I think Missy Bevers probably entered the church whether it was raining or not since she needed to have restrooms for the camp participants.
After learning a little more about Missy Bevers you cannot come to any conclusions about the timing either. Most of the time Missy Bevers arrived at 4 am to set up for the fitness class. On this particular morning, April 18th, 2016, she was running late. Therefore, it would make sense if someone was expecting her at 4 am.
The other reason behind it not being targeted is that the killer was not lying in wait looking outside for Missy Bever's vehicle, which they would have to know in order to be sure it was her. Without knowing her vehicle, the only way to verify she was the one entering the church would be to wait until she actually entered the church. Again the problem is that when the burglar stops to look at the camera and put their tool away after trying to pry open the first door on the surveillance video, the timestamp is 3:58 am. In my opinion, they did look outside at 3:58 am or at least it appears that way.
The manner of death is also debatable. What if she was not only shot, but also assaulted with the tools the burglar suspect had with them? I would expect a panicked burlgar to only shoot the victim and leave as quickly as possible, especially if they have no relationship to the victim and have their identity covered.
Also, another point has to do with the embroidery on the tactical vest the burglar was wearing. Maybe this person did that themselves? This is a possibility if that that design has never been found anywhere.
This case is a great example of coming to conclusions without knowing what the police know. The more information released, the easier it will be to decide whether this was a targeted or non-targeted crime. Until more information is released about what happened that morning, everyone is left guessing.
