Pilar Prades

Born into a humble family in Bejís, she moved to Valencia to enter service when she was twelve years old. Illiterate and introverted, she changed house several times until 1954 when she started working for Enrique Vilanova and Adela Pascual, a married couple who ran a farmhouse on calle Sagunto in Valencia. Prades worked in their home and even attended the counter of the deli when customers line up. On March 19, Adela falls ill with what is initially diagnosed as influenza and then dies. After her death, Enrique kicks Prades out of the house,[1] closes the business and leaves Valencia.[2]

Prades then goes to work at the home of the military doctor Manuel Berenguer and his wife Mª del Carmen Cid, recommended by Aurelia Sanz Hernanz, the cook. Soon, Aurelia falls ill. Berenguer is alarmed and takes Aurelia to hospital, where she seems to experience some improvement. When his wife exhibits the same symptoms, he consults other specialists and they perform a diagnostic test to confirm the presence of poison.[1] Suspecting Prades, he contacts Enrique Vilanova. After that, he files a complaint against Prades and Adela's body is exhumed, in which arsenic remains are found.

Although the evidence is considered circumstantial, since Prades confessed after 36 hours without eating or sleeping, a flask of an arsenic-based antkiller, which is thought to be the weapon of the crime, is found among her belongings. Despite the advice of her lawyer, she pleaded not guilty. She was sentenced to death by garroting.

The executioner designated to carry out the execution was Antonio López Sierra who, after knowing that a woman was going to be executed, refused to do so.[1] The execution, scheduled for six in the morning, was carried out more than two hours later, waiting for a pardon that did not arrive. The executioner had gotten drunk and had to be dragged to the gallows.[1][3]

Prades' life inspired the radio serial, usually called "La galleguita de la cara sucia (the little galician girl with the dirty face)"[2] in Argentina, with a great audience success.

The anecdote of the executioner taken to the gallows forcibly inspired the movie The Executioner by Luis García Berlanga.[1]

In the documentary Dear Executioners of Basilio Martín Patino, Antonio López is asked about the execution of Pilar Prades.

In 1985 the first season of the TVE series The imprint of crime was recorded, one of whose episodes was dedicated to the case of Prades. This was played by actress Terele Pávez in an episode directed by Pedro Olea. José Prades, Pilar's brother, sued TVE and the screenwriter for honor injuries, a lawsuit that was dismissed by the Supreme Court.[4]
