Investigation
The investigation by the Polícia Judiciária ended with the conviction for murder of Leonor and João Cipriano, Joana's mother and uncle. The prosecution claimed that Joana was killed because she saw her mother and João Cipriano, her mother's brother, having incestuous sex, in accordance with the testimony of the stepfather of Leandro Silva, the common-law husband of Leonor Cipriano. Leonor Cipriano confessed to killing her daughter. Her uncle confessed to having beaten her up after which she stood "quiet on the floor". He said he cut his niece's body in small pieces, put her in a fridge box, then put her inside an old car that was taken to Spain to be crushed and burned. When he was asked if he had sexually abused his niece he said in the presence of his lawyer "I did not harm her, I only killed her".
