He was thirteen years old, with a shy smile and a folder clutched in his hand. On May 6, 1971, in Genoa, Milena Sutter leaves school and disappears into thin air. Two weeks later, the sea returns her. Ballasted, strangled, without a reason. From that moment, the entire country stops. There is a red spider, an older boy, an anonymous phone call talking about a ransom. And a city that will never forget that name: Lorenzo Bozano, the “blond of the red spider”. Convicted, yes. But also a man who shouted his innocence until the end. So, half a century later, what still doesn’t add up in that story? In the analysis of Alessandro Politi, investigative journalist, the Sutter case as you’ve never heard it: between clues, silences and truths that the sea has never really returned.
