No body, no forgiveness: the murder that Tucumán could not solve: The disappearance and murder of Beatriz Argañarás
On July 31, 2006, a 45-year-old teacher leaves her home for work and disappears without a trace. Blood splatters in a freshly painted apartment, a car filled with fuel, and text messages would be enough to convict two women of murder, but the body would never be found. How do you prove a perfect crime when the victim remains missing?
In this episode, we explore the forensic investigation that faced impossible contradictions: alibis that didn’t add up, injuries on hands that spoke of a struggle, and a fuel record that placed the accused exactly on the route to El Cadillal. Susana Acosta and Nélida Fernández were sentenced to twenty years, but decades later they were granted parole without revealing Beatriz's whereabouts, leaving the most disturbing question of Tucumán justice open.
Victim: Beatriz Argañarás
Date: July 31, 2006
Location: San Miguel de Tucumán, Argentina
Status: Disappearance without a body; convicted on parole
- The apartment was painted and fumigated between the first and second searches, but Beatriz's blood remained on the bathroom frame, the wall, and the plumbing.
- Susana and Nélida filled up with gas twice on the day of the crime; the exact amount matched the trip from the apartment to El Cadillal and back.
- Luis Fernández's housekeeper testified that she washed one of his shirts with blood stains on the same July 31.
- Both convicted women married in prison as a pact of silence and obtained parole in 2023 and 2024 without revealing where the body is.
