Protesters spray-paint people's outlines on the ground during a demonstration by students from Ayotzinapa Teacher Training College "Raul Isidro Burgos" and other rural schools, along with activists, demanding the appearance of 43 students missing since September 26, in Chilpancingo, October 8, 2014. Mexican President Enrique Pena Nieto vowed on October 6 to hunt down those responsible for the apparent massacre of dozens of students in the southwest of the country that authorities say involved local security officials. The students went missing after they clashed with police in Iguala in the volatile, gang-ridden state of Guerrero on September 26. A mass grave was found near the town over the weekend, full of charred human remains. Guerrero's attorney general, Inaky Blanco, said on Sunday that 28 bodies have been found at the site so far, and it is "probable" that some of the missing 43 students are among the remains found in the graves.
