As previously reported, the sleeping bag itself was discovered tied to a dolly cart.

Residents nearby notified cops about the bag -- which had apparently been placed on the street for trash pickup -- and a man named Chad Irish was later arrested .

He's been charged with murder in the second degree, concealment of a human corpse and second-degree criminal possession of a weapon.
