Scene from 'Cocaine Cowboys 2' movie. Griselda Blanco (February 15, 1943 - September 3, 2012), known as La Madrina, the Black Widow, the Cocaine Godmother and the Queen of Narco-Trafficking, was a drug lord of the MedellÃn Cartel and a pioneer in the Miami-based cocaine drug trade and underworld during the 1970s and early 1980s. She was an important member of the Medellin Cartel but developed a bad rapport with the Cartel when she had the niece of the Ochoa family of the Medellin Cartel, Marta Saldarriaga Ochoa, murdered in order to not pay for a shipment of cocaine delivered by Marta. Her plan was to say she never received the shipment and that the young lady disappeared with it. After the young woman's body was found on a rural south Florida road, it became open season on Griselda and she was subsequently "on the run".
