Mexico City, July 27 (teleSUR-RHC)-- At least 60 clandestine graves and over 129 bodies have been found since investigations started into Mexico's now-infamous missing student case.

None of the remains belong to the 43 trainee teachers from Ayotzinapa, according to the report released by Mexico's attorney general's office. The report, obtained by the Associated Press news agency, shows that these numbers are not definitive and could be higher, given that the document only ranges from October 2014 to May this year. The report also only covers investigations in the state of Guerrero, the region of both the Ayotzinapa teacher training college and the city of Iguala, where the disappearances occurred, and AP's freedom of information request only covers those times mass-graves specialists were called in.

The students were disappeared in September last year by local police, who first shot at a bus load of students, killing six people, before handing the students to organized crime gang United Warriors, a group known to have ties to local government officials.

Reports have since found that federal police were monitoring the students, whose college is considered by the government to be a breeding ground for politicizing its rebellious students.

While forensics have identified the remains of one of the students, the other 42 are still missing, 10 months after the disappearances. To mark this, in Mexico City, hundreds marched Sunday to demand justice for the students. After the march, the relatives of the 43 missing students called on the government to provide credible evidence of the whereabouts of the students. They also announced the start of another nationwide tour to inform citizens – both in the north and south of the country – about their case, and to collect more information regarding forced disappearances and human rights violations throughout Mexico.

The country's National Human Rights Commission issued a report last week, documenting at least 30 omissions made by the government in the Ayotzinapa investigation that could prove vital in determining the students' fate. During their statements to the press on Sunday, the relatives of the 43, who are skeptical of the Mexican government, said the only evidence they will believe is two upcoming reports by a group of Argentine forensic experts and by the Inter-American Commission on Human Rights.
