The Heart inside a jar is needed to complete the "Dead Man's Hand" sidequest in Silent Hill: Downpour. It was ripped out of the chest of a prison inmate and left in a labyrinthine sewer. Murphy Pendleton can locate it in Pleasant River, underneath the house south on Rice Street in said underground labyrinth. The heart can be found by following the sound of its beating, which is louder and more rapid the closer Murphy gets to the heart. It must be reinserted into the inmate's chest to complete the sidequest.
