MEXICO CITY, April 30, 2025 (BSS/AFP) - Mexican federal investigators have found no evidence of mass killings or crematoriums at a drug cartel training ground whose discovery sparked international condemnation, a top public prosecutor said Tuesday.

In March, the Guerreros Buscadores, a collective of relatives of missing Mexicans, said it had found bones, shoes and clothing at a ranch that it described as a suspected "extermination center."

The group also reported that it had discovered crematoriums at the site.

Attorney General Alejandro Gertz, however, said that his investigators had found no such evidence at the site, which is believed to have been used by the Jalisco New Generation Cartel to train recruits.

"No corpses, bones, complete or partial skeletal remains were found," apart from some "very small" bone fragments, he told a news conference.

One body was discovered when the site was searched by state-level officials last September following clashes between the military and suspected members of a drug cartel, Gertz recalled.

According to the Jalisco state prosecutor's office, 10 people were arrested and two captives freed at the time.

Gertz's office took control of the ranch from state-level authorities in late March after relatives of missing persons, rights groups and the United Nations Human Rights Office called for a transparent investigation.

The attorney general is investigating if there was any collusion between local officials and the Jalisco New Generation Cartel, which has been designated a terrorist organization by the United States.

More than 120,000 people are missing in Mexico, which has a long history of human rights violations that remain unpunished.
