Florencia Aranguren: the crime on the beach that exposed a killer who never served his sentence

The dog that accused the killer of Florencia: The murder of Florencia Aranguren in Búzios, Brazil A recently arrived Argentine woman in Brazil disappears four days after landing. Her dog stays by her body, covered in blood, on the beach. The impossible: during the court hearing, the animal's reaction against the suspect was presented as identification evidence. In this episode, we explore how a man sentenced to 15 years for sexual abuse was still at large when he murdered Florencia; how security cameras, defensive scratches, and blood-stained clothing converge in 48 hours; and why a traumatized dog became a key witness in a court of justice. Victim: Florencia Aranguren, 31 years old, Argentine artist and trapeze artist Date: December 6, 2023 Location: José Gonçalves Beach, Búzios, Rio de Janeiro, Brazil Status: Pending jury trial; preventive detention - Carlos José de França had an active sentence of 15 years (2009) for robbery, assault, and sexual abuse of a minor, but was circulating in a semi-open regime without supervision. - Cameras capture Florencia entering a curve with dense vegetation; 20 minutes later, De França passes by on a bicycle wearing a cap; no one else is seen in the area. - Female underwear with blood stains was found in his home during the search; forensic analysis could reveal previous victims. - De França bathed immediately after the crime, but scratches on his body and defensive wounds on Florencia's hands contradict his denial in court.
