Corpse of a man with head almost completely severed was found on January 31, 2013 in a ditch in rural Caruaru, near the town of Bonito in Pernambuco, Brazil. The victim was identified as 36 year old José Ferreira da Silva who lived in the nearby community. He has not had any previous brushes with the law so the motive and who killed him are unknown.
Looks to me like he took a blow from a machete to the back of his neck. Probably a single blow, but it doesn’t take much to decapitate a man with a machete.
