Protesters spray-paint people's outlines on the ground, meant to represent those used for dead bodies at crime scenes, during a demonstration to commemorate the 46th anniversary of a student massacre in Mexico City, and to protest against the disappearance of 43 students from Ayotzinapa Teacher Training College, in Chilpancingo, in the Mexican state of Guerrero, October 2, 2014. Mexican authorities are searching the violent western state of Guerrero for the 43 people who have been missing since September 26 after a series of clashes in the southwestern town of Iguala involving students, police, and armed men, and the state governor said photos showed police had taken some of them away.
