Three employees of Goldcorp’s Los Filos Mine who were believed to have been abducted were found dead in Mexico. A fourth employee was set free, according to family members.

Reuters reported that the corpses were found in a mass grave in Guerrero state and showed signs of torture. It was the same state where 43 trainee teachers were abducted late last year and apparently massacred, in an incident that sparked President Enrique Pena Nieto's deepest political crisis.
State authorities declined to comment when asked about the discovery.

The state prosecutor's office said on March 6 that four employees of Goldcorp, the world's biggest gold producer by market value, had possibly been kidnapped. Prior to their disappearance, they were believed to be headed home after finishing their shifts at the Los Filos Mine.

“The information available to us about this incident is limited, however the disappearance of the employees was unrelated to their role with Goldcorp,” Goldcorp spokeswoman Christine Marks wrote in an email to Reuters.

“The employees were not at the mine conducting Goldcorp business or in Goldcorp-supplied transportation at the time of the incident,” she added.
