Investigators have found the remains of one of the 43 Mexican students who disappeared in 2014, prosecutors announced Tuesday (local time). It is the second time that human remains have been identified in the case.

In November last year, bones were found in the Mexican state of Guerrero. In all, more than a hundred bones were found, but only a few were suitable for DNA testing. Identification by researchers from the University of Innsbruck, Austria, now shows that one of the bones of one of the missing students, Christian Alfonso Rodríguez Telumbre, is.

"This is a new era," said the prosecution. "More than five years after the incident, human remains of one of the victims have been identified." Only once, in December 2014, a body was identified in the case.

The 43 youngsters disappeared in September 2014 after riots in the city of Iguala. Presumably, police officers kidnapped them during a demonstration by order of the mayor. Then they are said to have been turned over to a drug gang. The Mexican army may also have been involved in the disappearance.

Thousands of people protested disappearance

In January 2015, the students were officially declared dead. The authorities assumed that all 43 were "kidnapped, killed and burned". Then their bodies would have been thrown into a river. The discovery of the remains contradicts that story.

The case sparked protests across Mexico from thousands of people. They protested the authorities, who hold them responsible for the disappearances. The current president, Andrés Manuel López Obrador, promised to take notice of the matter when he took office.
