A woman who identified herself as the mother of missing student Adan Abarajan de la Cruz, 23, sits next to Mexican army soldiers standing in front of the entrance to the 27th Infantry Battalion base in Iguala, Mexico, Thursday, Dec. 18, 2014. Relatives of the 43 missing students blocked the entrance to the base in protest over the army's alleged responsibility or lack of response during the night of Sept. 26 when 43 students were taken by municipal police and then handed over to a drug gang to be killed and then the bodies burned, according to the results of the Attorney General's investigation.
