Editing Cattle mutilation (section)

==Later incidents==
Many cases of mutilation have been reported worldwide since the 1967 Snippy incident, chiefly in the Americas and Australia. In South America, an estimated 3,500 incidents have occurred since 2002, when around 400 cases were reported.<ref>{{cite book|last1=O'Brien|first1=Christopher|title=Stalking the Herd|date=2014|publisher=Adventures Unlimited Press|location=Kempton, IL|isbn=978-1-939149-06-0|page=438}}</ref> Mutilation investigators assert that a large number of cases are never reported to authorities, perhaps no more than one in ten.<ref>{{cite book|last1=O'Brien|first1=Christopher|title=Stalking the Herd|date=2014|publisher=Adventures Unlimited Press|location=Kempton, IL|isbn=978-1-939149-06-0|page=547}}</ref>

In 1993, photographic evidence surfaced of a mutilated male human corpse that was found near the [[Guarapiranga]] reservoir of [[São Paulo]], [[Brazil]] in 1988. The victim's identity was kept private. Theories ranged from a mundane criminal act of [[homicide]], to more fantastical speculation alleging [[alien abduction]] due to perceived similarities with UFO-related animal mutilations. An autopsy report concluded the wounds occurred while the victim was still alive, and the associated pain resulted in cardiac arrest. However, another independent investigation later concluded that he died from natural causes.<ref>Сlaudeir Covo, Paola Lucherini Covo, Tânia da Cunha «O Caso Guarapiranga».
