Questions raised by international forensic experts over claims that the remains of a second Mexican student forcibly disappeared last September have been identified expose the sadistic lengths the Mexican government would go to show they are taking action on the case, Amnesty International said.

The Argentine Forensic Anthropology Team (EEAF) last night said tests conducted by Austrian forensic experts from Innsbruck Medical University, allegedly identifying a piece of bone as belonging to student Jhosivani Guerrero de la Cruz, were not conclusive.

“The Mexican authorities’ baseless claims to have identified Jhosivani’s remains reek of desperation and of a cruel attempt to show they are taking action ahead of the one year anniversary of the student’s enforced disappearance. It looks like they are willing to stop at nothing to wash their hands of any responsibility over one of Mexico’s most shocking human rights tragedies in recent history,” said Erika Guevara Rosas, Americas Director at Amnesty International.

“Instead of playing games with the lives and hopes of the relatives of the disappeared students, the Mexican authorities must make a serious and concerted effort to re-direct investigations and ensure no stone is left unturned until the whereabouts of all 43 students are established.”
