Mexican authorities have begun exhuming 116 bodies found buried in a mass grave in the central state of Morelos.
The rural grave, discovered last November in the town of Tetelcingo, consists of two 10m (33ft) deep pits.
Prosecutors say that the bodies may have been dumped illegally by morgue officials, but the investigation into who is responsible is ongoing.
Morelos is among the worst-affected states in Mexico’s epidemic of drug-related violence.
At least 20,000 people have disappeared across Mexico, the UN estimates – other organisation put the number far higher.
Investigators at Tetelcingo worked under a yellow tent as families of missing persons and National Human Rights Commission representatives looked on.
Genetic samples will be taken from each set of remains to attempt identification before they are reburied in marked graves.
