Crime has always been among the most urgent concerns facing Mexico. In 1964, two serial killers who were siblings; Delfina and María de Jesús González (also known as Las Poquianchis) from the north-central Mexican state of Guanajuato were convicted of having killed prostitutes they recruited and an unknown number of clients.
Each receiving a maximum 40-year prison sentence; 19 other members of the slave ring, including other family members, were reportedly also given jail sentences.
Delfina and Maria de Jesús Gonzalez grew up hungry and abused in El Salto de Juanacatlan, Jalisco. Their father, Isidro Torres was a violent man. They were raised by a father who ruled with an iron fist and didn’t think twice about abusing his children if they failed to follow the code of conduct he created for them.
This included small infractions, all the way down to how his daughters dressed. He imprisoned his daughters for wearing make-up, and even shot a man dead once in an argument.
Raised to be cold-hearted and fear poverty, the Gonzalez sisters saved some money and opened a saloon in San Pancho which gave them some stability. But not enough for their taste, they decided to aim higher.
From the 1950s until the mid-1960s, the sisters ran a brothel in Rancho El Ángel, the locus of their largescale prostitution ring, abducted young teenage girls; forcing them into drug abuse and sexual slavery with their clients.
Virgins who were brought in were set-aside for special customers who paid higher rates to deflower the girls. None of the women ever saw a dime for their dreadful duties.
Their most gruesome act was forcibly aborting fetuses when victims were found pregnant; the girls would be beaten until the baby was dead. When they became unattractive, caused trouble, got sick because of starvation, an STD, or complications from an abortion, they would be starved to death, or beaten by the other women with sticks and logs.
On some occasions, they would also kill customers who showed up with large amounts of cash. This cycle continued for nearly a decade, before one of the sex slaves was able to get away. She rushed to the police station and spilled out the horrors of what was happening in the brothel.
They were soon arrested and later sentenced to jail, following a raid on their hideout on January 14th, 1964. A dozen women were discovered, all malnourished and scared. Underground, were found over 91 women, men, and fetuses corpses.
In October 1968, Delfina died in prison. Maria was released from prison after she completed her sentence and dropped out of sight after her release. The Gonzalez sisters became so infamous that in the 2000s, Guinness book of World Records tagged them the “most prolific murder partnership” in human history.
