[The ghosts seemed to keep him on his toes. For a bit, anyway. He's energized enough to list his findings in the pit.]

Other than all the knife wounds, Neku had a bullet shot through the side of his head. Another bullet was in the pit, which might indicate it had missed. The gun itself, despite all the blood, was completely clean and has three bullets left in it.

There was bruising on Neku's arms, but otherwise, he died without a struggle. His headphones were playing music, even.

Two other things I found in the pit is this drawing - it's covered in blood, though - and a torn-up bedsheet.
