Inquiry

>Check the doors.

You think it's safe to say that this is something interesting.

In the first room, you see a desk with papers spread out on the floor in front of it. One of the papers is shredded, and another seems to be made of pink fiberglass insulation. It's also possible that someone dropped their sculpture of a head and then spilled their sweet and sour sauce under it, but the truth is probably a tad more murdery.
The second room looks like a common area, with a bookshelf, table, and weights.

You could investigate more, but there is a guy waiting for you upstairs, and it's not like the stuff will be gone. The elevator looks perfectly functional, which is good because there aren't any stairs. The fire department would disapprove.
