I got no backinfo, and there’s too little and very faint talk in the video to make a location guess. However pretty much everybody wears flip flops. Including the victim who is shown barefoot, which usually means he was wearing flip flops and lost them when he collided with whatever killed him.
The video is an apparent aftermath of a fatal traffic accident. The victim is shown with head partially ripped off his shoulders. It looks like the head is still attached to the torso with a bit of skin, but other than that, he’s for all intents and purposes… decapitated.
Props to Best Gore member @natural-selection-2 for the video:
