Despite massive protests in Mexico to demand justice for the disappearance of 43 students in the southern state of Guerrero, the Government still shows no new research to be met eight weeks of the tragedy.

The president was referring to the marches involving tens of thousands of Mexicans to remind young people missing in Iguala and demand justice to a state that does not stop to take responsibility in the case. The families of the 43 students Ayotzinapa who disappeared on 26 September at the hands of corrupt police and criminals returned Friday to experience moments of frustration and anger at the lack of progress in official investigations.

After participating in the protests Thursday in the capital, parents gathered on Friday for the third time with the National Security commissioner , Monte Alejandro Rubido, and the director of the Criminal Investigation Agency prosecutor Thomas Zerón in Chilpancingo , the capital of Guerrero.

“They’re upset because no progress in the investigations,” said lawyer parents of missing youths, Vidulfo Rosales after the meeting. After the meeting, the relatives expressed anger with cries of “murderer,” “liar” or “return to our children” and threw objects Zerón vehicle when leaving the place.

According to Rosales, the only new information provided by officials was the arrest of the Secretary General of Council of Cocula , Cesar Ramirez Nava, who is allegedly linked to the disappearance of the students.

Furthermore, Rubido informed them that the Inter-American Commission on Human Rights (CNDH) appoint 10 people from Latin America to assist in the investigations.

Counsel explained that at this meeting the authorities did not mention progress in the investigation and not on genetic testing to the skeletal remains found in a dumpster Township Cocula neighbor matches, which are carried out in a laboratory in Austria.

According to research, 43 students were arrested by police and handed over to the cartel Warriors United on a night in which six people were killed and 25 wounded in shootings allegedly ordered by the mayor of Iguala, Jose Luis Abarca.

According to the testimony of three members of Guerreros States, students of a school for teachers Ayotzinapa were killed and incinerated in the trash because they thought they were members of the rival group, The Reds.

Fellow youth and family do not believe this version , based on statements from criminals who might be lying, until there is no scientific evidence to endorse it, and have therefore kept the protests to demand justice and the development of students.

The lawyer Friday distanced the movement of isolated acts of violence that took place on Thursday in the Mexican capital, where groups of hooded clashed with riot police that left two wounded officers and thirty prisoners.
