Among the social problems in Mexico, over the last few decades, is the insecurity brought about mainly by organized crime. This increases the need to incorporate forensic science in the recognition of the victims of violent events. The participation of archaeologists is essential, though law enforcement agencies seem to be unaware of this need. A striking case took place in December 2010, with the disappearance of a group of hunters in León, Guanajuato. In July 2011, the Procuraduría General de Justicia del Estado de Zacatecas (Attorney General of the State of Guanajuato - PGJEZ) decided to intervene in the search and requested the help of archaeologists; the forensic investigation was carried out at the ranch called Las Negritas, in Calera, Zacatecas, where it was assumed the remains of nine of the hunters were deposited, according to information gathered from one of the survivors. Within the group aiding the investigation were archaeologists and bioarchaeologists, who managed to recover hundreds of human bones, mostly of men. Accord-ing to the genetic profiles obtained from the dna, it was only possible to determine the genetic affiliation of one of the hunters from one vertebra, according to the statement released by the At-torney General of the state of Zacatecas.
