Seven corpses, including some with signs of torture and a decapitated body, were discovered in the violence-plagued southern Mexican state of Guerrero, authorities said on Thursday.
The bodies were all male and were discovered in the mountainous Zitlala township, according to a statement from Guerrero's prosecutor's office.
The statement said the corpses displayed "visible signs of torture" and forensic experts were dispatched to examine the bodies.
A local police source told AFP that some of the bodies had bullet wounds and injuries caused by a sharp weapon.
The corpses were first discovered Wednesday, and bad weather delayed the investigation until Thursday when authorities could finally reach the grisly scene.
The prosecutor's office said one of the dead was a member of a local Guerrero drug cartel, Reds.
Guerrero is one of Mexico's poorest and most dangerous states, plagued by drug-related violence and crime.
Last month, four bodies were discovered in a pick-up truck in the state, just days after 10 bodies were found in clandestine graves on the outskirts of Acapulco in a separate incident.
