The pits with the two bodies were found in Chilapa late Thursday, said Roberto Alvarez Heredia, spokesman for Guerrero state's security coordination group.
They were located some 500 meters (yards) from a field where five bodies were unearthed from three clandestine graves between May 31 and June 6.
At the same location, authorities found the woman's remains in three plastic bags that were dumped in a 20-meter (65-foot) deep well, Alvarez said yesterday.
Chilapa lies in a mountain region where opium poppies are grown and drug cartels fight for control of heroin trafficking.
