Authorities in the western Mexican state of Sinaloa found the bodies of two young men, one of them identified as the nephew of drug kingpin Joaquin "El Chapo" (Shorty) Guzman, the country's most-wanted fugitive.

The victims - identified as Juan Guzman Rocha, nephew of "El Chapo," and Jose Miguel Bastidas Manjarrez - were found gagged and with several gunshot wounds on a rural road near the small town of Aguaruto, spokespersons for the Sinaloa Public Safety Secretariat told Efe Friday.

Authorities at the scene, including agents from the state Attorney General's Office, concluded the men were likely killed elsewhere after they found no spent shell casings near the bodies.

Guzman Rocha was under investigation by a U.S. federal court in Chicago as part of a larger probe of the Sinaloa drug cartel and its leaders, spokespersons for the state AG's office told Efe.

"El Chapo" Guzman heads the Sinaloa mob, which authorities say has the biggest share of the drug-smuggling business in Mexico and the largest narcotics-distribution network in the United States.

Both the Mexican and U.S. governments have posted multi-million-dollar rewards for information leading to the capture of the crime boss, who was arrested in Guatemala in 1993 but escaped from the Puente Grande maximum-security prison in the western state of Jalisco on Jan. 19, 2001.

The 54-year-old Guzman, who remains at large, is worth at least $1 billion, according to Forbes magazine.
