A body found in the state of Guerrero was identified as a rebel leader who accused the governor of ties with drug trafficking.
The director of the Ministerial Investigative Police, Valentin Diaz Reyes, said the body was exhumed on Thursday and forensic analysis confirmed that this was the insurgent. The body had four bullet wounds.
Solis Guerrero or "El Comandante Ramiro" also accused President Felipe Calderón of protecting the "Chapo" Guzman cartel and had said that governor Zeferino Torreblanca Galindo did the same with the former mayor of Petatlan, Rogaciano Alba Alvarez.
The ERPI emerged in the late 1990s and clashed with the army in 1998. Its members have rarely appeared in mountain villages in recent years.
