Ana Lídia Braga disappeared outside her school in September 1973. No one was ever convicted, and the case became a lasting symbol of unanswered questions during Brazil’s military dictatorship.

Seven-year-old Ana Lídia Braga disappeared in Brasília on September 11, 1973 after being left at school. Her body was found the following day. The case became one of the capital’s most notorious unsolved crimes, both because of the brutality of the homicide and because suspicions touched people connected to powerful families during the military dictatorship.
She vanishes after being left at school in Brasília.
Police open a high-profile homicide investigation.
No prosecution results in a conviction.
The homicide remains unresolved.
Her name is preserved in a city park and historical archives.
Historical court and public records place Ana Lídia’s disappearance at approximately 1:50 p.m. outside Colégio Madre Carmen Sallés. Witness accounts described a man leaving with the child, but no identification ultimately produced a conviction.
The inquiry generated allegations involving politically connected families and accusations that authorities failed to pursue evidence consistently. Later records also documented censorship surrounding public discussion of the case.
Several names circulated in police files and the press. None was convicted of Ana Lídia’s murder. This distinction matters because decades of retellings often present historical suspicion as though it were a final judicial finding.
By the 1990s, the criminal case had reached prescription. A 1997 Folha report stated plainly that the crime had never been solved.
The Parque Ana Lídia in Brasília carries her name. The case remains part of the city’s historical memory and of discussions about censorship, elite influence and the protection of children during the dictatorship period.
Crime by Region separates allegations, confessions, police theories and final court findings. When sources disagree, this file uses cautious wording rather than presenting the most sensational version as established fact.
