Netflix has greenlit a new three-episode installment of its Italian original “The Monster of Florence,” the serial killer series directed by genre specialist Stefano Sollima. The first four-episode chapter launched from the 2025 Venice Film Festival before dropping on the streaming giant, where it rapidly rose to the top of Netflix’s global non-English-language shows chart.

Shooting is underway on what is being described as “a new chapter in Italy’s most famous true crime case” that “will revisit the Monster of Florence investigation through a new lens.”

The true crime show’s title is the moniker given to the alleged serial killer, who committed eight double murders over the course of 17 years from the late 1960s to the mid-’80s, preying on couples parked in cars in secluded places around Florence. “The Monster of Florence” always used the same weapon: a .22 caliber Beretta.

The first “Monster of Florence” season delved into the initial line of police investigation, known as the “Sardinian lead,” with each of the show’s four episodes telling the story of a man who, at one point in time, investigators believed was the killer. This new chapter now expands the narrative surrounding the Monster of Florence case by focusing on the so-called “Snack Buddies” lead. In particular, it focuses on the figure of Pietro Pacciani, a Tuscan farm worker who was convicted in 1994 for seven of the eight double murders. His conviction was overturned on appeal in 1996, and he then died in 1998 before his retrial. Pacciani is described in the statement as “figure as scrutinized by the media as he was shrouded in mystery” in what remains one of the longest-running and most controversial criminal investigations in Italian history.
