An indigenous woman has been burned alive in Paraguay after being accused of witchcraft, a local prosecutor confirmed Wednesday. The prosecutor, Fany Aguilera, said members of the Mbya Guarani ethnic group tied the woman, Adolfina Ocampos, 45, to a wooden pole and shot arrows at her before they burned her alive. Ms. Ocampos was sentenced to death last week by the community’s chief in Tahehyi, a village about 180 miles north of the capital, Asunción. The date of the killing was unclear. Nine men in the village have been charged with first-degree murder.
