In this April 21, 2015 photo, snapshots with brief descriptions of missing people are tacked to a board in the San Gerardo Catholic Parish in Iguala, Mexico. Little attention had been paid to the many people who have disappeared or been kidnapped in this region until 43 students from a rural teachers college disappeared in Iguala, Sept. 26, 2014. Two months after the students disappeared, hundreds of families began coming forward to tell their stories, emboldened by the international attention focused on the missing students.

A convoy of armed men had arrived in town and once they had left, 17 residents including Victor, had disappeared, never to be seen again. They are among the 25,000 Mexicans who have disappeared since 2007, according to the government’s count. Victor was 15 years old when he was taken.

In this April 22, 2015 photo, Mario Vergara explains how the pigmentation of rocks helps him as he looks for clandestine graves amidst dry vegetation on the outskirts of Iguala, Mexico. Vergara says that some stones have the look of having been recently unearthed in the digging of a grave rather than always having been on the surface. 

In this May 31, 2015 photo, a group of relatives of missing people walk in a field as they search in vain for a site of a possible clandestine grave after they received an anonymous tip, in Iguala, Mexico. Since the government began excavating suspected graves found by this group scouring the surrounding mountains looking for their loved ones late last year, more than 100 bodies have been exhumed though most still await identification.

In this April 22, 2015 photo, a man inspects a sandal during a search for clandestine graves in the dry brush on the outskirts of Iguala, Mexico. Authorities are of little help, say residents who have seen local police escorting gangsters through town and consider them to be a uniformed extension of Guerreros Unidos. That relationship was reinforced by the government investigation into the case of the 43 students, which concluded that Iguala and Cocula police had turned them over to members of Guerreros Unidos, who then killed them and disposed of the incinerated remains in Cocula. 

In this Aug. 19, 2015 photo, a child flies a kite as others look out from an observation point overlooking the city of Iguala, Mexico. Iguala was thrust into the national and international limelight on Sept. 26, 2014 when three students were killed and 43 others disappeared allegedly at hands of the local police who then handed them over to a drug gang that disposed of the bodies, according to a federal investigation. The focus on Iguala has emboldened hundreds of local families to come forward and speak up about their own missing relatives. The families’ message was simple: there are many more missing. They called them “the other disappeared.”

In this June 1, 2015 photo, Rosa Segura Giral makes pizza in her home, in Cocula, Mexico. In the days that followed her daughter's disappearance, Segura Giral retreated to her bed inside a darkened house. For months, she did not go out. For more than a year, she refused to make pizzas. “One has to learn to survive. I tell you, I hope that my daughter shows up.” Segura Giral said, her voice fading to a whisper. “I feel like any day she is going to come back. I feel so much like she has been traveling.”

In this Aug. 18, 2015 photo, the day ends in Iguala, located in a poor region of the southern Mexican state of Guerrero.

At least 292 people have been added to the list of missing from the area since the 43 disappeared there on Sept. 26, 2014.

This is an 84-photo composite of people, each holding an image of their missing relative. The photographs of the 84 were shot between April and August of 2015 in the city of Iguala and surrounding towns. The world, and even most of Mexico, paid little attention to Iguala until 43 students from a rural teachers' college disappeared on Sept. 26, 2014. Two months after the students disappeared many other families in the area began coming forward to tell their stories, emboldened by the international attention focused on the missing students. Their message was simple: there are many more missing. They called them “the other disappeared.” The AP interviewed the relatives of 158 of those missing. Only 84 agreed to be photographed because they are still very fearful.
