A high-ranking member of the Los Zetas drug cartel captured near the border between the northern states of Nuevo Leon and Coahuila is linked to more than 50 murders, including that of a U.S. agent, the Mexican government said Friday.

During the presentation of Jesus Sarabia Ramon to the media, Defense Secretariat spokesman Ricardo Trevilla said the suspect had ordered his henchmen to kill 50 people and kidnap and extort at least 20 businessmen.

He also linked the detainee to “countless attacks on police and military” personnel.
