The head of extradition for the Mexican Attorney General's Office says it probably will take at least a year to extradite Joaquin "El Chapo" Guzman to the United States.

Officials had previously estimated a six-month minimum, but Jose Manuel Merino told local media that the extradition would probably take "one year or longer." Merino told Radio Formula that the length of the process would depend on how hard the defendant's lawyers fight each stage. Merino said the process had lasted as long as six years, in one case.

The Attorney General's Office issued a statement Sunday it's started the extradition mechanism by notifying Guzman that two arrest warrants from the U.S. are being processed.

Guzman was recaptured Friday, six months after breaking out of a Mexican prison.

Guzman's attorney Juan Pablo Badillo has said that the defense already has filed six motions to challenge extradition requests.
