@nypost: A 14-year-old Brazilian boy died after injecting himself with butterfly remains — with police investigating if it was part of a twisted online challenge, according to a report. Davi Nunes Moreira reportedly started to vomit and then developed a limp after mixing a dead butterfly in water and then injecting the liquid into his leg. The teen told his dad he hurt himself while playing — but then confessed what really happened when he continued growing sicker and was admitted to a hospital in Planalto, the report said. Davi was rushed to another hospital in Vitoria de Conquista, the state of Bahia’s third largest city, but sucumbed to his injuries. 📸: Getty
