A woman's remains were found in a well and two corpses were discovered in clandestine graves in a southern Mexico municipality where five other bodies were found recently, authorities said.
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.
At least 16 people were reported missing in Chilapa in May of last year after an armed group of 300 people occupied the town for several days.
Chilapa lies in a mountain region where opium poppies are grown and drug cartels fight for control of heroin trafficking.
