The doctors arrive while he is still breathing, while life runs away in red streams. Marco Mameli, 22, a worker from Ilbono, dies killed by a stab wound to the chest, in the heart of the party, a stone's throw from the center invaded by the crowd . The confetti washed away, blood remains, on the asphalt of via Santa Cecilia. Somewhere beyond the reeds, towards the mountains, there is a killer on the loose, with his hours numbered.

The police, led by the deputy police commissioner Fabrizio Figliola, try to tighten the net immediately. The specialists of the Scientific Police arrive, dozens of witnesses are heard during the night. All those who participated in the brawl or alleged brawl are potentially investigated and could have serious consequences from a criminal point of view.

It is difficult not to have seen anything, complicated to make it explicit. At five in the morning the hearse with its sad burden takes the road to the hospital. Bari Sardo is barely breathing, mortified in the most anticipated celebration. Everyone is looking for answers that do not come. The magistrate in charge of the investigation, Dr. Giovanna Morra, could order an autopsy on the worker's body in the next few hours.
