In this Nov. 29, 2014 photo, Maria Roman, wearing a shirt that reads in Spanish "I'll search for you until I find you," pauses to rest while searching for clandestine graves on the outskirts of Iguala, Mexico. “I have a lot of fury, a lot of hatred,” says Roman, who's looking for her 17-year-old son Marco Antonio Mendez Roman who disappeared in April 2013. Emboldened by international attention on 43 disappeared college students, dozens of parents have come out to hunt for their own children who have been missing for months or even years, digging as they'd never dared before, and as authorities never bothered to do.
