The Doctor and the Convict

The police fixated on two primary suspects:

1. Il Dottore (The Doctor): Francesco Calamandrei, a respected Florentine physician. He was a brilliant, arrogant man with a taste for the occult. Investigators believed he was the intellectual mastermind, the "professor" who commanded the killer. He was arrested, spent years in jail, and was eventually released without conviction. He died in 2020, always maintaining his innocence.
2. The Farmer: Pietro Pacciani, a rustic, illiterate farmer with a violent past and a penchant for bestiality. Pacciani was the face of the Monster. He was convicted in 1994 for the 1984 and 1985 murders. However, the evidence was circumstantial at best. Bullets found in his garden were later proven to have been planted.

The Vinci Theory: The Most Plausible Suspect

While the official verdict lists Pietro Pacciani (deceased) as the principal, along with Vanni and Lotti as accomplices, most serious criminal investigators consider the case wide open. The Preston-Spezi investigation points to a man named Antonio Vinci.

• The Location: Vinci lived in the heart of the murder zone. He knew every back road.
• The Weapon: Vinci had access to military-grade weaponry and family members in the Italian police, providing him with ballistic knowledge.
• The Accomplice: The theory suggests Vinci acted with his brother-in-law, Francesco Calamandrei (the doctor), who provided the surgical knowledge for the mutilations.
• The Silence: Vinci was questioned but never arrested. He remains alive and free, refusing to speak to authorities.

3. Key Characteristics of the Killer

• Method: Ambushed couples in parked cars at night in isolated hilly areas (mostly dirt roads with olive groves).
• Weapon: A .22 caliber Berda semiautomatic pistol (never found).
• Mutilations: Female genitals post-mortem (cut out and removed). Experts believe the killer had anatomical knowledge, possibly medical or hunting background.
• Behavior: Long intervals between killings (months or years). Some investigators suggest an accomplice, possibly a couple or group.
