16-year-old Brazilian teen kills student and injures two in school massacre after exposure to online self-harm group on Discord and Telegram

May 1, 2024Portugal, Brazil1 source

Summary

A 17-year-old Portuguese teen named Mikazz led an online group called The Kiss, which encouraged minors to engage in self-harm, animal torture, and violent acts. In October 2023, a 16-year-old Brazilian teen named Luluzinho, influenced by Mikazz, carried out a school massacre in Sapopemba, São Paulo, killing one student and injuring two others. Mikazz was arrested in Portugal on May 1, 2024, after police linked him to the group’s activities on platforms like Discord and Telegram. The group operated with a strict hierarchy, requiring members to perform violent acts to ascend in rank, including self-mutilation and animal cruelty. The Brazilian authorities are considering extradition requests, as the most severe crimes and planned attacks occurred in Brazil. The group’s activities were facilitated through virtual platforms, with servers located in the United States, complicating the investigation.
