Edgar Valdez Villarreal is believed to be the chief hit man for one of Mexico's most brutal drug cartels.
His nickname? "Barbie."
That's right, the American fashion doll. Because the U.S.-born Valdez has blond, blue-eyed good looks.
cThe Associated Press reports Mexican drug trafficker nicknames run from flashy and threatening to surreal and downright goofy.
Some reflect a thug's rank in his cartel, others simply a school yard taunt that stuck. Still others denote a reputation, such as the cartel leader known as "El Mas Loco" -- "the Craziest One."
Law enforcement officials say they list as many aliases as they can for each suspect.
