I would also like to draw attention to another aspect of the evidence found by Suga and myself.

The footprints and handprint that we found were positioned in such a way that indicated whoever left them jumped off either the roof or the wall. I'm no expert, but while it didn't look physically impossible, it would still likely prove difficult for an amateur to do so without injuring themselves. This leads me to believe that our culprit is at the very least somewhat athletic.
