Eight bodies were discovered in clandestine graves outside the southwestern Mexican port city of Acapulco after the arrest of an organized crime suspect, authorities said.
The Guerrero state Attorney General's Office said in a statement that two corpses were found Thursday in a district known as Pueblo Nuevo, bringing to eight the total number of bodies discovered at the site.
State AG's office personnel, in coordination with Mexico's army and navy and members of several police forces, on Thursday resumed excavation work at the site where six bodies had been located the day before.
The human remains covered in sand and lime - including the bodies of at least two women - were found in at least three graves, according to media reports.
The Sol de Acapulco newspaper said on its Web site that the graves were discovered after a suspect was detained by navy personnel taking part in the search for five missing people.
One of the missing persons was a professor at the Autonomous University of Guerrero, Trinidad Hernandez Gonzaga, who was kidnapped earlier this week on campus by armed men and found dead Thursday with a gunshot wound to the head, the daily said.
The man's body bore signs of torture and he was killed after his family had paid a ransom, the paper reported.
Guerrero Gov. Angel Aguirre Rivero launched a security operation last year with the support of the federal government to improve security in the southern state.
"Operation Safe Guerrero" was launched on Oct. 6, 2011, in an effort to reduce the soaring crime rate in the state.
The wave of drug-related violence in the state has been blamed on a turf war between rival cartels. EFE
