Featured in the documentary "Cocaine Cowboys". Was also the basis for Evelda Drumgo, the female drug kingpin in the opening of the movie "Hannibal". Clarice Starling shoots her down in botched drug raid in Baltimore. A 69-year-old woman known throughout the drug world as the "Godmother of Cocaine" was gunned down by an assassin on a motorcycle in Colombia Monday, according to international news reports. Griselda Blanco, once listed alongside Pablo Escobar as one of the "most notorious drug lords of the 1980s" by the Drug Enforcement Administration, was fatally shot as she left a butcher's shop in western Medellin Monday afternoon, according to a report by Univision and El Colombiano. Colombia's El Espectador reported authorities are looking for Blanco's killers and are investigating possible motives for the killing. Blanco served nearly 20 years in an American prison on drug trafficking charges and was at one point tied to as many as 40 murders in the U.S., according to a 1997 Senate testimony given by then-director of DEA international operations Michael Horn. Horn said that Blanco ordered a Florida mall shooting in 1979 that left two dead and four injured, and she apparently enjoyed her line of work. "To foster her reputation as the 'Godmother' of cocaine, [Blanco] named her fourth son Michael Corleone, after the fictional mob character portrayed in the movie 'The Godfather,'" Horn said. Court documents filed in 1988, three years after Blanco was caught, detail the shadowy, decade-long hunt for the queenpin that involved federal agents chasing false identities and checking Miami hospitals for gunshot wound victims that matched Blanco's description. But she wasn't able to elude them forever and after being captured in 1985 in Irvin, Calif. and serving nearly two decades behind bars in America, Blanco was released from prison and deported back to Colombia in 2004. The DEA referred all inquiries into Blanco's death to Colombian authorities, telling ABC News, "she served her time here." The Colombian National Police did not immediately respond to requests for comment for this report.
