Twenty-three-year-old psychology student Beatriz Lebre was killed in Lisbon in May 2020. A fellow student was arrested and reportedly confessed to police, but he died in custody before a criminal trial could determine guilt.
Beatriz Lebre was a 23-year-old psychology graduate from Elvas studying for a master's degree in Lisbon. Her family reported her missing after losing contact with her in May 2020. Investigators quickly treated the disappearance as suspicious.
The Polícia Judiciária announced the detention of a 25-year-old man after investigators found strong indications of homicide. Contemporary reporting identified him as Rúben Couto, a fellow student of Beatriz.
Police sources told Portuguese media that Couto confessed to killing Beatriz and provided information about what had happened after her death. Those statements are significant investigative evidence, but they were never tested in a criminal trial because Couto died before proceedings reached that stage.
On May 29, 2020, authorities recovered the body of a young woman from the Tagus River near Santa Apolónia in Lisbon. Subsequent reporting identified the victim as Beatriz. The recovery transformed what had begun as a missing-person inquiry into a homicide case with a known victim and a detained suspect.
After appearing before an investigating judge, Couto was placed in preventive detention, the most restrictive pretrial measure available under Portuguese law. Preventive detention is not a conviction: it reflects the judicial assessment of risk and the seriousness of the allegations while an investigation continues.
On July 5, 2020, Couto was found dead in his cell at Lisbon Prison. He had been awaiting trial. His death meant there would be no criminal verdict determining guilt, no adversarial testing of the reported confession and no sentencing proceeding.
That procedural fact is central to the current status. Media frequently described Couto as the confessed killer, but this archive does not convert a confession reported by police into a conviction that the courts never entered.
Beatriz was murdered. Police detained Couto on strong suspicion and multiple reliable outlets reported that he confessed. He then died in custody before trial. No other person was convicted of Beatriz's murder.
Because the prosecution ended before adjudication, the appropriate editorial status is unresolved / no trial, while noting the unusually strong investigative evidence against the deceased suspect.

A confession reported by police is not the same as a final judicial finding. This page records the confession as part of the investigation while making clear that the suspect died before trial.
