A cartel leader and hitman fond of videotaping torture sessions and decapitating likely dozens of enemies has gone missing from a federal prison in Florida, where he was serving a 49-year sentence.

As of November, Edgar Valdez-Villareal, a Mexican American cartel leader, had been mysteriously removed from the federal Bureau of Prisons website. He is now listed as “not in BOP custody” even though his release date is not until July 27, 2056.

Valdez-Villareal, 49, is known by his underworld moniker “La Barbie,” and headed up the Los Negros, an enforcement group of the Beltran Leyva cartel — one of Mexico’s most ruthless underworld groups. At one point, he was a top lieutenant for the Sinaloa Cartel, run by convicted drug dealer Joaquin “El Chapo” Guzman-Loera.
