Boy, 14, who injected himself with butterfly for online challenge suffered a 7-day slow death

A Brazilian teenager has died following a medical emergency tied to an incident he initially kept secret, turning what might have been treatable into a quiet tragedy marked by fear and delayed disclosure. In a small Brazilian city, 14-year-old Davi Nunes Moreira was hospitalized after developing severe symptoms, including vomiting, intense pain, and difficulty walking. At first, he told family and doctors he had been hurt while playing, but as his condition worsened over the following days, it became clear a far more serious situation was unfolding.
