Mothers of some of 111,000 people who have disappeared in Mexico over decades of violence on Wednesday marked the International Day of the Disappeared with protests and demands that the government do more to locate their loved ones. Edith Pérez Rodríguez, one of the marchers, wore a T-shirt with photos of her two sons, Alexis and José Arturo Domínguez Pérez. “If we don’t search for our children, nobody will do it,” said Pérez Rodríguez.
