MEXICO CITY — Convicted drug lord Joaquin “El Chapo” Guzman, who twice pulled off brazen jailbreaks and is fighting to avoid extradition to the United States, was transferred to a prison in northern Mexico near the Texas border early Saturday. Lawyers for Guzman, who was recaptured in January, have filed multiple appeals against their client being sent to the U.S., and Mexican officials have said it could take as long as a year to reach a final ruling.
