MEXICO CITY — A judge has ruled that drug kingpin Joaquin Guzman will stay for the immediate future in Mexico, where authorities say there is no chance that the man known as "El Chapo" will escape his cell in the nation's highest-security prison.

The judge said Tuesday that Guzman will stand trial on drug trafficking charges.

Mexico's top officials say he must face all local charges and interrogation by investigators looking to dismantle his multibillion-dollar cartel before possible U.S. extradition.

But experts say the government hasn't proven able to match such headline-grabbing arrests with long-term investigations and prosecutions of deep-rooted criminal networks. Cases have stalled, cartels keep operating and last year one of Guzman's closest allies walked out of the prison where the U.S. said he was running drugs from behind bars.
