Bird (4)_2

What exactly did he encounter, and what happened to him?

Perhaps a closer look at the portion of the corpse below the neck might yield some answers.

Rags?

Ground meat?

Jam?

Minced flesh?

It could have been any substance mixed with red and white, except it was impossible to believe that this was a human body.

Forensic scientists had seen many gruesomely deceased bodies: the masterpieces of killers, unlucky souls caught in machinery, and poor devils who were nearly hacked into pieces by ship's propellers after drowning. But this body... cuts, burns, frostbite, crush injuries, blunt force trauma, electric shock injuries, corrosive wounds...

The perpetrator was definitely a sadist, utterly infatuated with the sensation of tormenting others, to the extent that they had utilized every known method of inflicting pain on this man, and may have even recorded the entire process with audiovisual equipment, taking something from the victim as a memento.
