Back in September 2014, some 43 students also went missing after the gang-linked police attacked their buses and handed them over to members of a drug gang.

Mexico officials say the members of the Guerreros Unidos drug cartel have confessed to killing the young men and burning their remains after receiving them from corrupt police officers.

The case has sparked protests against President Enrique Pena Nieto’s administration.
