A DNA test is carried out during a campaign to test family members of missing people in Orizaba, Veracruz, Mexico, May 6, 2019. Each relative must submit a DNA test in order to identify bodies found during searches. Although data are supposed to be shared between regions, this rarely happens. Families are forced to repeat the test several times, with some obliged to carry out more than a dozen tests in the course of the search for their loved one. REUTERS/Mahe Elipe
