lawyer is still waiting for an investigation to provide answers and establish who was responsible for her son's death. there are many cases that have been going on for decades sometimes. one case is over twenty years old. and the perpetrator still hasn't been identified. i. guess. if a mistake was made in operations then of course there will be an internal investigation into what happened so that ultimately whoever is responsible will be punished. but silva no longer believes that there'll be an investigation into her son's death . it's usually the poorest most vulnerable sectors of society in rio who are paying the price for the escalating violence and children in the city slums in particular
