No backinfo. The video shows two men dead on the road after being apparently run over and crushed to death by a large vehicle. There is a bus shown with the scrapes on the pavement leading up to it, so perhaps that’s the vehicle that killed them?
The men wear what looks like worker uniforms. They may have been vehicle repairmen working on the truck stopped on the side of the road? At least one had brain matter batted out, and there’s even a large skull fragment out on the road.
Props to Best Gore member @boscotkc for the video:
