Eight years after the disappearance of 43 students in Mexico, relatives have criticized backsliding in the investigation. The accused were recently arrested, said the family's lawyer, Vidulfo Rosales, at a protest march in Mexico City. However, several other arrest warrants were canceled again. On the fringes of the rally, there were clashes between some masked demonstrators and the police, as was seen on television.

On the night of September 27, 2014, corrupt police officers abducted the students from the Ayotzinapa teacher training college in the southern city of Iguala and handed them over to the Guerreros Unidos criminal syndicate. The background to the fact has not yet been fully elucidated. Only bone fragments from three of the young men have been found and identified so far.

Most recently, a truth commission had described the act as a state crime and declared the students dead. The committee said the military were also partly to blame. The then commander of the 27th Infantry Battalion in Iguala and the former Attorney General were arrested after the report was published.
