I just got a chance to rewatch the surveillance video in more detail/more closely. I have a few questions and statements regarding it.
1) I find it very odd that the perp casually walks around, looks into rooms, basically spends a lot of time on the surveillance camera. Typically when a perp knows that cameras are recording it is the opposite - they either try to do something to disable or disarm the camera, or they don't worry about it and get in and out in the shortest amount of time. So, does this mean that the perp isn't aware of the cameras? Maybe the perp doesn't, in fact, have as much knowledge of the church as I originally thought. I just find it eery that he/she is pacing around, reading the bulletin board, going and out of rooms, basically just "hanging out" waiting for MB..if he/she knew they were on camera the entire time why act so casual and why spend so much time on camera?
2) Around the 55-57 second mark on the video, what is the perp doing in front of the bulletin board with his/her hands?
3) It's apparent (to me at least) that the perp is not comfortable wearing the heavy uniform, but I think the odd walk/stature is actually due to the boots/shoes. I think the boots are purposely too big (either to throw off LE if a print is found, or simply because they didn't want to wear a pair of their own boots due to possible DNA). Those are not the suspects boots, and therefore it is causing he/she to walk strange.
4) Speaking of the uniform, I think I asked this the other day but I can't remember the answer - where would the suspect be able to purchase something like that? I can't imagine those are readily available at many stores around town. Is that a costume type uniform (maybe from a Halloween supply type store) or a more authentic one that would need to be purchased through a specialty website?
5) I still can't get a good handle on whether or not the perp is a man or a woman, but I'm leaning towards female at this point.
