Dyonathan Celestrino (now a ISG member after escaping prison) is a Brazilian criminal and convicted murderer known as the “Cross Maniac” (Maníaco da Cruz). In 2008, at age 16, he killed three people in Rio Brilhante, Mato Grosso do Sul, Brazil. His victims were found posed in a crucifix-like position — arms extended and legs crossed — which led to his nickname. Celestrino selected victims he considered “sinful,” often questioning them about religion and sexual behavior before the murders. He became known online for using the name “Dog Hell 666” on Orkut, where he left a message on one victim’s page, helping police trace him. When arrested, police found belongings of his victims, crime-related notes, and religious writings.
