What Have They Done to Your Daughters?

The police found Silvia's naked body hanging from the rafters in an attic apartment, which closely resembled a suicide scene. Her mother had also reported her missing as a runaway, supporting the initial suicide theory. However, the autopsy revealed she was approximately two months pregnant, making suicide unlikely since she had no history of emotional distress.

Earlier in the film, Silvia's mother finds birth control pills in her daughter's coat pocket, hinting at a secret life.

While reviewing footage of a student demonstration, Vittoria Stori noticed Silvia entering a different building around the time of her death. This observation suggested someone moved her body to the attic after killing her elsewhere, proving it was murder rather than suicide.

The tape recordings hidden by Rosa in the hospital vent revealed a clandestine operation where powerful men in the community paid for sex with underage girls. Silvia Polvesi was one of the victims, and the recordings contained her voice, confirming her involvement. The ring included prominent political figures whose names were listed in Beltrame's files.

Silvia's mother discovering birth control pills in her daughter's coat pocket foreshadows the exploitation ring.

The butcher Roberto Meichiorri killed Ruggero Talenti. Talenti was investigating the prostitution ring on behalf of Silvia's mother before he was dismembered and his remains were found wrapped in plastic bags in the trunk of his own car. The killer wanted to silence him before he could reveal what he discovered.

Mrs. Polvesi mentions hiring a private detective who later dropped the case, hinting at danger.

Professor Beltrame was killed because he possessed incriminating files listing the names of men involved in the prostitution ring, including powerful political figures. After the police falsely reported that Paglia had confessed, Beltrame became a target. He was found dead in his bathtub in an apparent suicide, but he was actually murdered to prevent him from testifying.

Beltrame's files were mentioned as evidence linking high-profile individuals to the ring.

Police learned that a local butcher had recently purchased a motorcycle, with tire tracks matching those from the killer's vehicle. They obtained a photograph of the suspect from his father, who said his son had left home three months earlier. When two young girls spotted Roberto near a piazza, police cornered the area and identified him during the confrontation.

The killer's motorcycle was established early as a key piece of evidence.

The masterminds of the prostitution ring escaped prosecution. After Roberto Meichiorri was killed, Silvestri's superiors discouraged any further legal action against the ring's organizers, arguing it would take months to gather evidence and that the main killer was already dead. The powerful men implicated in Beltrame's files were never charged.

Bruno Paglia was murdered because he was a key witness who had recruited girls into the prostitution ring, including Giuliana Bigi. After learning that Paglia had been arrested photographing Silvia, the killer feared he would cooperate with police. He was killed at his home to prevent him from testifying.

Giuliana Bigi reveals that Paglia recruited her into the ring.

Vittoria Stori narrowly survived a nighttime attack in her apartment building's parking garage when the killer, Roberto Meichiorri, ambushed her. The exact details of her survival are not fully shown, but she managed to escape with injuries. This attack intensified the police hunt for the killer.

Silvestri told the press that Paglia had survived the attack and confessed to police as a strategic maneuver to draw out the real culprits. This false information was intended to panic the prostitution ring members into making mistakes or taking actions that would expose them. The tactic led directly to Beltrame's murder.

Rosa, the secretary and mistress of the murdered private detective Talenti, revealed she had hidden tape recordings in a hospital vent. These recordings exposed the entire underage prostitution ring, implicating powerful men in the community. The tapes provided the crucial evidence connecting Silvia's death to the larger criminal network.
