The accident happened at around 5 am on Friday May 31, 2013 in the town of Vertentes in Pernambuco, Brazil about 50 km north of Caruaru. An unidentified man was struck by a truck while doing whatever on the road. The impact was so violent, the man was decapitated and a piece of truck broke off. The body also appears rather badly mangled, as though the man was dragged (or run over by other cars while already dead and headless on the road).
As is very common, the victim was stripped half naked by the accident, although his genitalia were censored out. Scary how you could end up not only dead, but also humiliated.
