The cold case of Stefano Gonella has been reopened, the 26-year-old from Bergamo stabbed to death at dawn on 24 September 2006 in his house in via Passarotti, on the outskirts of Bologna , where he worked as a night porter in a hotel.

Thanks to the testimonies of a neighbor and the roommate who was sleeping and was awakened, an identikit of the killer was created, but the investigations never managed to locate him.

The investigation was reopened in 2010 , once again to no avail. So what has changed? Twelve years of new technologies and knowledge that could unlock the investigations and finally give a face to Gonella's killer.

The investigators are holding a DNA that belongs to the murderer , on which new and more sophisticated analyzes can now be made. The genetic profile can also be entered into the national law enforcement database created in 2016.
