The convicted Colombian drug smuggler known as the “Godmother of Cocaine,” Griselda Blanco, 69, was gunned down by a motorcycle-riding assassin in Medellin, Colombian national police confirmed late Monday, according to the Miami Herald.

Blanco spent nearly 20 years in prison in the United States for drug trafficking and three murders before being deported to Colombia in 2004, the Herald reported.

Two armed riders pulled up to Blanco as she was leaving a butcher shop in her hometown, and one shot her twice in the head, the Herald reported, citing a report in El Colombiano newspaper.

Family members said Blanco had cut her ties to organized crime after returning to her country, the BBC reported. Police said they were investigating the motive.

Blanco was one of the first to engage in large-scale smuggling of cocaine into the United States from Colombia and set up many of the routes used by the Medellin cartel after she was sentenced in the United States in 1985, the BBC reported.

Investigators told the Herald that they estimate conservatively that Blanco was behind about 40 slayings. She was convicted in connection with three murders: Arranging the killing of two South Miami drug dealers who had not paid for a delivery, and ordering the assassination of a former enforcer for her organization, an operation that resulted in the death of the target’s 2-year-old son, the Herald reported.

Three of Blanco’s husbands were killed in violence related to drugs, the Herald reported, and one of her sons was named Michael Corleone, a reference to “The Godfather” movies.

Blanco is credited with originating motorcycle assassinations, the Herald reported.

“This is classic live-by-the-sword, die-by-the-sword,” filmmaker Billy Corben, who with Alfred Spellman made two “Cocaine Cowboys” documentaries, told the Herald. “Or in this case, live-by-the-motorcycle-assassin, die-by-the-motorcycle assassin.”
