Overview
- Netflix released a four‑part Italian limited series on October 22 that revisits the case without endorsing a single theory.
- At least eight couples were slain around Florence between 1968 and 1985, with police only connecting the crimes in 1982 via Winchester “series H” .22 Beretta ballistics.
- Former lead investigator Michele Giuttari has challenged the ballistic linkage and the related “Sardinia trail” theory as unproven.
- More recent forensic testing found DNA tying multiple scenes together, but it does not match victims or any well‑known suspects.
- The legal record remains unsettled, with central suspect Pietro Pacciani convicted and later acquitted before a retrial, and associates convicted in parts of the investigation.
