I'd like to point out something that has been bothering me for a long time where I think LE's timeline may be wrong (this isn't the first timeline for me to disagree with, like I dispute the current Mansion Murders timeline). The basic issue I have is that there's approximately 30 minutes of footage and LE gives 30 minutes between the perp entering and Missy arriving:

If there's only hallway footage and the cameras are motion activated, the perp could have conceivably spent the night in one of the rooms sleeping there. For instance it's said that the perp went into various offices, but unless there's room cameras as well, the perp could have spent an indefinite amount of time in each of the rooms vastly stretching the timeline. Potentially the only reliable camera times I'm seeing are based on the gun store camera that presumably runs 24/7 that shows when Missy and then the camper arrived and if that too could be off where they would have to look at the 911 call timestamp and tie that to the gun store camera.
If for instance there is no camera footage in the kitchen and the perp did break-ins around the kitchen, there would be no way to capture what time that happened. Conceivably the perp could have already been at the church then disabled the exterior cameras and staged the broken doors and windows to only make it look like they broke in. It would be pretty obvious that this was targeted if there had been no signs of breaking in, but without some independent way of timing that, the broken windows and doors could mean many things and could have happened over a wide range of hours instead of needing to happen around 4 AM. This could also explain the lack of clear detail on any vehicles entering the church prior to Missy, which the perp could have arrived the day before for church (or broken in Sunday night), spent the night and then been picked up after all the LE and campers arrived during all that confusion and activity.
