Bodyguard of El Chapo's sons killed after jailbreak

Joaquin "El Chapo" Guzman -- shown in this handout picture released by Mexico's interior ministry on January 19, 2017 as he was being extradited to the United States -- will now go on trial in September

The head bodyguard of the sons of captured Mexican drug lord Joaquin "El Chapo" Guzman has been killed by soldiers while on the run following a jail break last month, officials said Saturday.

Francisco Javier Zazueta Rosales died in a gunfight with Mexican marines on Friday near the northwestern town of San Cayetano in Sinaloa, the state that was El Chapo's stronghold, according to a statement by local prosecutors.

Zazueta had been locked up in February but escaped through the front gates of his jail on March 16 with four other detainees, including the son of another cartel chief associated with Guzman. The prison's head of security disappeared soon afterward.

Guzman, who twice escaped prison in Mexico, is being detained in the United States after being extradited in January.

He has pleaded not guilty to a 17-count indictment filed by US authorities including the charge of leading the powerful Sinaloa drug cartel. No trial date has been set.
