Just a few things about this case from my observation and curiosity.
The video. At about :19 of this video the perp starts doing something that seems to confuse a lot of people:
I personally think that up until :39 or so, this person is using the door as leverage to do something with an object. Many people think he/she is trying to pry the door open. I think it is likely that they are not doing that, but are using the door as a holder instead of putting something on the ground or a table. I know it sounds strange, but the way they use that hammer at the end to smoothly go over the top of the object is eerie to me. I still cannot jog a good explanation for that.
Also, at about 1:45 in the video the perp is seen breaking glass. Some people think its really weird that they hit the glass with such a wimpy looking flick of the wrist. I may have an explanation for that. When I worked at a place with heavy snow, one of my responsibilities was to break the ice off of the generators when they became frozen over. At first, I hit it full force, but then the ice flew into my face. I noticed myself hitting the ice with a wimpy wrist in order to control how hard the shards flew back at me.
I have always wondered if the reason the perp was opening so many doors is because they were looking for what room Missy was going to be setting her class up in, so they could ambush her.
Missy's family. Why do we only hear from Brandon, his stepmother, and his father? They all seemed to be super loud and vigilant, but I cannot seem to find anything, anywhere, where any of Missy's family has spoken out.
The struggle she put up. There has always been the question of why or how Missy was not able to fight back, although she was in really good physical shape. I have wondered if she didn't really want to hurt the person attacking her. Maybe this person was someone she knew she could overpower but was just trying to get them to relax and merely defend herself.
The gun. In some online research, I have seen where people narrowed down her case as unsolved homicide by a firearm. Does this mean specifically lead, gunpowder, and bullet casings? Or could this be a
firearm but not exactly what we are used to thinking of when we hear that?
I personally would really like to see this case solved one day. There is too much video footage for it to have gone on this long IMO.
