MEXICO CITY - Mexican authorities have found four more clandestine graves containing charred human remains at a site in the restive southwest of the country, where officials fear missing students were massacred by gang members and police.
Attorney General Jesus Murillo said on Thursday the motive behind the apparent massacre of dozens of student teachers, who went missing after clashing with police in Iguala in the volatile, gang-ridden state of Guerrero on September 26, was not yet clear.
The new find brings the number of graves discovered on the outskirts of Iguala to 10. Murillo said DNA samples were being taken from their relatives to check against the remains found.
Thousands marched through the Mexican capital on Wednesday to demand the government find out what happened to 43 missing students.
