I was leaning more into the theory that someone was obsessed with Missy....a friend that she worked out with stated that
Missy wasn't her self the last couple of weeks.......someone loved her ideal life and was jealous......that could to point why LE can't say for sure if it was a woman or man dressed up as a swat.]
Not sure if it's OK to quote part of this article so I just used a few key words from it and included the link. Of course this is just opinion from a former prosecutor.
"Veteran prosecutor...thinks the killing was anything but random... the person was trying to get the drop on the victim
* to make them think youre police so that they can feel safe around.
Here is the link to this article.

Since it doesn't sense to me for the perp to walk around causing minor damage to fool LE, it does make sense if they were just trying to fool Missy. So they could get her where they wanted her. Maybe they knew she would recognize them otherwise and be unwilling to be near them.
