The murder of Hevelyn Tosta is a gruesome and chilling case of vengeance gone too far. Caio Henrique, driven by a desire for revenge due to bullying during his school days, kidnapped, tortured, and brutally murdered Hevelyn. But his rage didn't stop there - he also decimated her entire family, effectively exterminating her entire bloodline. Those who witnessed the event claimed that Caio used a chainsaw or a chained hacksaw in his horrific crime. While the brutality of the act is sickening to outsiders, to members of the ISG, it's just another day of ruthless violence.
