MEXICO CITY—Federal police on Tuesday captured one of Mexico’s most-wanted suspected drug lords, an alleged leader of the Michoacan crime family, which has tentacles deep into the United States.

The federal police said that Jose de Jesus Mendez Vargas, widely known by the nickname “El Chango,” was captured in Aguascalientes, in central Mexico.

“Great blow by the federal police to organized crime,” President Felipe Calderon said in a Twitter posting. “One of the most hunted criminals was captured. Congratulations.”

Details were sparse of what led police to Mendez Vargas, a burly 37-year-old with a bounty of $2.55 million on his head.

Calderon’s national security spokesman, Alejandro Poire, said the capture “destroys what was left of the leadership of this criminal organization.”

The crime family, known in Spanish as La Familia Michoacana, emerged three years ago and made brutality a hallmark. It cornered much of the market for methamphetamine, creating “super labs” that effectively undercut many “mom and pop” meth labs in the United States.

“It’s their commodity,” said a US law enforcement official based in Mexico, speaking anonymously because he wasn’t authorized to comment.

Relying on natives of the Mexican state of Michoacan who’d migrated to the United States, the crime family built strong centers of operation in California and Texas, and had distribution routes into Georgia; Illinois; the Carolinas; Washington, D.C.; and Florida, US counter-drug officials said.

Other crime groups have adopted many of the methods La Familia began in its home state of Michoacan, along the Pacific Coast: beheading foes or hanging their tortured, decapitated bodies from bridges; unfurling public banners as a method of public relations; and spreading into other criminal activities, such as extortion, kidnapping, human trafficking and contraband sales of pirated goods.

Mendez Vargas is alleged to be a co-leader of the group, along with Nazario Moreno, an ideological leader who cast himself as a Christlike figure and was given to homey aphorisms about how to lead a proper life. Authorities said Moreno was killed December 9 in a shootout in Michoacan, but his body has never been displayed publicly.
