Miriam Elizabeth Rodríguez Martínez's relentless quest for justice after the tragic kidnapping and murder of her daughter, Karen Rodríguez, by the Los Zetas cartel, is a heart-wrenching tale of a mother's love and determination.

In January 2012, the nightmare began in San Fernando, Tamaulipas, Mexico, when armed men from the notorious Los Zetas cartel abducted Karen. The kidnappers demanded a ransom, and despite the family's compliance, the story took a tragic turn. In 2014, Karen was killed, and her remains were discovered on an abandoned ranch.

Refusing to let her daughter's death go unpunished, Miriam embarked on a daring and dangerous mission. She worked tirelessly at night, adopting various disguises, using a fake handgun, and carrying false identification. Her singular focus was to uncover the truth about her daughter's fate and bring the perpetrators to justice.

Miriam's journey led her to confront several members of the Los Zetas cartel, known for its brutality and violence. The Daily Mail highlights her extraordinary efforts, demonstrating her fearlessness in the face of immense danger. Among her targets was a young florist, whom she pursued for years, eventually tracking him down online after learning about his past life before joining the cartel.
