Dead bodys don't bleed so much that means that dude was cut up while he was still alive...

I- (°_°)

omg what the fuck?! (⊙…⊙ )

Or they recently died like 1h ago or smt

After watching Criminal Minds so much, I dare to say that the dude was alive when the chop chop happened.
He gathered all that info on purpose, so why throw it away that easily? My guess is that the dude was drugged, but died from blood loss, so our psycho here just ended up discarding him.

Yep.

He has blood splatters on his face that means the dudes heart was beating when his arteries were cut
