The boy who cries in the photo is Diego Frazao Torquato, who played the violin in the String Orchestra of the Afro Reggae. Afro Reggae is a non-profit organization that gives kids hope and an escape from their impoverished and crime ridden environments. The occasion was the funeral of his social project coordinator, Evandro João Silva, who was murdered in downtown Rio. Diego contracted meningitis at age four, aggravated by pneumonia, and struggled with memory difficulties.
He still managed to learn the violin. Diego, born and raised in the slums of Parada de Lucas, dreamed that the violin would take him to see the world. Sadly, shortly after this photo was taken Diego died of acute leukemia and meningitis. He depended on the help of machines to regulate blood pressure and had a cardiac arrest.. At Diego’s funeral José Júnior, the coordinator of Afroreggae stated, “I think the legacy of Diego is hope, it is the willingness to change, to transform”.
