Okay, a couple of things after looking at your map and watching the footage:
Your map is INCREDIBLY helpful. I had the perp on three different hallways during the footage before and that wasn't the case using your map. He/she stays right around the awning entrance area. (ETA: Except towards the beginning, you do seem him coming down the hallway towards the bulletin board and that is from the kitchen side/opposite to the awning side.) It's chilling to watch with the map and your mind starts really going a million miles an hour trying to figure out what he/she was doing there. This helps so much, thank you for all of your hard work!
Tip for everyone that watches the footage using the map: Pause a lot the first time you watch.....and maybe the second time too. Consult the map constantly. Make sure you stop and think about where the cameras are because otherwise your directions will get messed up. Use the accordian looking door as a reference. Then watch a couple more times until you really understand where the perp was in the building.
I am still not clear on where the perp was at the end of the footage. Hence my next question!
Do you think Room 12 would be on that same hallway (where he/she entered in the first scene of the footage?) Or, do you think it would be on the other side of the building? I just wonder how the doors are numbered. It doesn't look like there's enough room for Room 12 on your map for it to be on the side of the building with the kitchen. Any ideas about where it might be? Just wondering....I can absolutely research it if you aren't sure and are completely exhausted.
