Okay. As near as I can tell, since the murder occurred, that part of the church has changed. I have to find a source frame from a news video to be more certain of what I want to say about that but I can use an image I had previously used for another purpose. Don't get distracted too much by the labeling in the image.
In particular, I have to go back and get frames from that news video and isolate a different part over the reporter's left shoulder (to the right in the image). I indicate doors across from each other in that area on the map and that is still likely the case. But, the presence of the dark wall with the clock and fountain I am not sure were there. My impression is that the "hall" went further back toward the west. How, far I can't tell from any images we have but if I recall from examining the enlarged frames from that news video that there was some depth west of where the dark door is seen over the reporter's shoulder. This is why on the map I show the "hall" continuing west of the SW entry doors.
