The 1992 murder of actor Daniella Perez led to two convictions and a nationwide campaign that helped expand Brazil's Heinous Crimes Law.

Daniella Perez was a 22-year-old Brazilian actor and dancer working on the television drama De Corpo e Alma when she was murdered in Rio de Janeiro on December 28, 1992. Fellow actor Guilherme de Pádua and his then-wife Paula Thomaz were tried separately and convicted of qualified homicide in 1997. Daniella's mother, writer Gloria Perez, organized a major petition that helped persuade Congress to include qualified homicide in the Heinous Crimes Law.
The actor disappears after work and is found later that night.
Investigators focus on Guilherme de Pádua and Paula Thomaz.
Gloria Perez campaigns to strengthen the legal treatment of qualified homicide.
Congress expands the list of heinous crimes, including qualified homicide.
A Rio jury convicts him of qualified homicide.
A separate jury also returns a qualified-homicide conviction.
Daniella was early in a successful career and newly married. Her work made the case nationally visible, but fame did not make the loss more or less serious than another homicide. Her mother's campaign consistently returned attention to Daniella as a daughter and working artist.
Contemporary coverage frequently repeated intimate material and dramatic reconstructions. An evidence-based summary needs only the relationship between the defendants, the investigation and the court outcomes.
The defendants were tried separately before juries in Rio de Janeiro. Both were convicted of qualified homicide, including findings about motive and the victim's reduced ability to defend herself. These verdicts established criminal responsibility.
Later parole and release history does not undo those convictions. Sentence execution under the law then in force is different from a finding of innocence.
Gloria Perez gathered more than one million signatures in a public campaign. The National Congress later enacted Law 8,930 of 1994, adding qualified homicide to the Heinous Crimes Law and strengthening the legal consequences for future crimes.
The reform was not applied retroactively to transform the defendants' legal situation. Its importance lies in democratic mobilization and future law, not in rewriting the rules of a case that had already begun.
Pádua and Thomaz were convicted in 1997. The campaign associated with Daniella's case helped change the law for future treatment of qualified homicide; it did not retroactively change the offense date.
