Mexico City, January 29 (RHC-EFE) –- The parents of the 43 students kidnapped four months ago in the southern state of Guerrero say Mexico’s attorney general has no scientific proof to support his assertion that the youths were killed and their bodies burned.

“We repudiate the form in which the attorney general (Jesus Murillo Karam) is brazenly trying to close” the probe into the events of September 26th in violation of assurances given by President Enrique Peña Nieto, the spokesman for the families, Felipe de la Cruz, told a press conference.

“We will not permit them to close the investigations with only the statements of the murderers,” he said hours after Murillo Karam insisted that evidence and testimony “fully” confirm his office’s theory of the crime.

The lawyer representing the students’ families, Vidulfo Rosales, said he plans to travel to Geneva next week to denounce the Mexican government before the UN Committee on Enforced Disappearances.

Murillo Karam’s office needs to carry out a broad and exhaustive investigation to “learn the truth of the events,” Rosales said, asserting that the government is in a hurry to close the case ahead of the June 7th mid-term congressional elections.
