A 53-year-old man was found dead in the hallway of the house, stabbed to death, while his 19-year-old son was found in the bathroom with stab wounds, in serious condition and with a knife in his hand. It happened in the afternoon in an apartment in via dei Liburni in Rome. A passer-by called the police who intervened on the spot. The young man was transported in red code to Umberto I. The dynamics of the facts need to be clarified.
