Pilar Prades Santamaría (1915–1959), known as “La Envenenadora de Valencia” (The Poisoner of Valencia), holds a tragic place in history as the last woman executed in Spain, put to death on February 19, 1959, by garrote vil—a brutal strangulation device—for poisoning her employers with arsenic.
A maid who worked in various households, Prades’ crimes began when her mistresses fell ill mysteriously, leading to deaths attributed to her lacing food with rat poison to steal valuables or settle grudges. Arrested in 1955 after an exhumation revealed arsenic in a victim’s body, she confessed under pressure but later recanted, claiming coercion.

Her trial, amid Franco’s repressive regime, resulted in a death sentence despite pleas for mercy. The executioner initially refused, deeming it too barbaric for a woman, but proceeded under orders, highlighting the method’s cruelty—slow strangulation via a screw-turned collar. This “horrific” execution, the last for a woman in Spain before abolition in 1978, symbolized the era’s harsh justice for the poor and marginalized.
Examining it objectively reveals gender biases in punishment, the garrote’s dark legacy, and societal failures in addressing poverty-driven crime, underscoring the need for humane reforms and empathy in modern justice systems.

Pilar Prades was born in 1915 in Valencia, Spain, into poverty, working as a maid from a young age amid the hardships of post-Civil War Francoist Spain. Her life spiraled into crime in the 1950s: employed in households, she allegedly poisoned mistresses and others with arsenic-laced food, motivated by theft or resentment. The pattern emerged when employers fell ill mysteriously—one died in 1954, leading to her dismissal. In another home, similar symptoms raised suspicions, prompting an investigation.
Arrested in 1955 after police found arsenic in her possession and an exhumation confirmed poison in a victim’s system, Prades initially denied but confessed under interrogation, admitting to multiple killings (estimates vary from 4 to 13, though convicted for one). She later retracted, claiming torture, but the confession stood in a biased trial. Sentenced to death in 1956, appeals delayed until 1959.
Garrote vil, Spain’s primary method since 1820, involved strapping the condemned to a post with an iron collar tightened by a screw, crushing the neck for slow asphyxiation—often 10-20 minutes of agony, promoted as “humane” but notoriously brutal. For Prades, the executioner, Vicente López Copete, refused initially, citing moral qualms about killing a woman, but relented under pressure, fearing job loss.

On February 19, 1959, at Valencia Prison, Prades was led to the garrote after last rites. Strapped in, the screw turned, causing excruciating pain until death. Witnesses reported her screams; it took several minutes. Her body was buried anonymously.
This last female execution under Franco highlighted class and gender disparities—Prades, poor and uneducated, received no mercy, unlike some elites. Abolished in 1978 with Spain’s constitution, the garrote claimed thousands, its legacy a reminder of authoritarian cruelty.
Pilar Prades’ horrific garrote execution, the last for a woman in Spain, underscores the barbarity of Franco-era justice, where a maid’s desperate crimes led to a slow, agonizing death after the executioner’s moral hesitation. This case, amid poverty and repression, reveals how systems punish the vulnerable disproportionately. By reflecting objectively, we confront the ethics of cruel methods, inspiring modern abolitions and reforms focused on rehabilitation. This history urges societies to address inequality’s roots, ensuring justice serves humanity rather than vengeance, building futures free from such painful legacies.
