Griselda Blanco, the drug kingpin known for her blood-soaked style of street vengeance during Miami’s “cocaine cowboys” era of the ’70s and ’80s, was shot to death in Medellin by a motorcycle-riding assassin Monday. Blanco, 69, spent nearly two decades behind bars in the United States for drug trafficking and three murders, including the 1982 slaying of a 2-year-old boy in Miami. Called the “Godmother of Cocaine,” she was deported in 2004 to Colombia, where she maintained a low profile.  Colombia’s national police confirmed her slaying late Monday. According to Colombian press reports, two gunmen on motorcycles pulled up to Blanco as she walked out of a butcher shop in Medellin, her hometown. One man pumped two bullets into her head, according to El Colombiano newspaper. It was the sort of death many had predicted for her: Blanco has been credited with inventing the idea of the “motorcycle assassin” who rode by victims and sprayed them with bullets. “It’s surprising to all of us that she had not been killed sooner because she made a lot of enemies,” former Miami homicide detective Nelson Andreu, who investigated her, said late Monday. “When you kill so many and hurt so many people like she did, it’s only a matter of time before they find you and try to even the score.” The former kingpin was with a pregnant daughter-in-law, who was uninjured. According to El Colombiano, the woman told police that Blanco was no longer involved in organized crime and that she was hoping to live off the sales of several properties she owned. Blanco came to epitomize the “cocaine cowboy” bloodshed of the 1980s, when rival drug dealers brazenly ambushed rivals in public. Miami Herald
