Alondra Luna Nuñez smiles after attending a press conference upon her arrival to the Bajio International Airport in Silao, Mexico, April 22, 2015. The 14-year-old Mexican girl, who was taken from her school by police and sent kicking and screaming to the U.S., returned home after DNA tests showed she is not related to an American woman searching for her missing daughter. There was no immediate explanation of why authorities did not confirm her identity before sending her out of the country. AP
