Relatives of 43 missing students in Mexico give their blood to build a DNA bank to try and find their loved ones, who went missing in September. Yiming Woo reports.
Family members of Mexico's missing students give their DNA, hoping that will help federal investigators to find their loved ones. Forty-three teachers in training disappeared in Guerrero in September, after clashing with local police. Some of their relatives say they don't trust the state authorities and are scared of being targeted themselves. (SOUNDBITE) (Spanish) RELATIVE OF MISSING STUDENT, ESPERANZA MELENDEZ, SAYING: "It's always about fear, fear because if you speak out against something the authorities pay no attention to what you're speaking out against. Now, however, they're investigating us to see where we work, if we're involved in bad things. They're trying to cling onto something and don't pay any attention." Investigators suspect the students were killed by corrupt officers working with drug gang members. The case has sparked a few violent protests. Many say the government isn't doing enough to stop endemic gang violence that's killed thousands. That's put President Pena Nieto on the defensive. (SOUNDBITE) (Spanish) MEXICAN PRESIDENT ENRIQUE PENA NIETO, SAYING: "We have warned violent movements that are taking advantage of this pain of putting on protests for protests' sake, protests that sometimes don't have a clear objective. It seems they're responding to an interest which is to bring about destabilisation, to create social disorder, and above all else, to try and act against the project of the nation that we're driving." He took office two years ago promising to restore order in the country.
