This evening, officials are studying a new tape from the terror group accused of kidnapping those 200 school girls in Nigeria, members of that group making fun of the message, bring back our girls. You'll remember Michelle Obama helping the cause. The defiant message and the new champion to bring home the girls, Malala. Amy robach is with Malala and some of the girls who escaped before. Reporter: The defiant new video message from boko harm, mocking the campaign, bring back our girls. More than 200 girls tonight still in captivity. We traveled to Nigeria to meet with some of the girls who escaped. The trauma still written on their faces. This 18-year-old describing how she jumped off a truck, badly injuring her leg. What was it like when you escaped? I hid in the bushes of an abandoned Vil age. This 15-year-old also leapt from a truck. Slowly she made her way to her village. She didn't eat for a week. These girls have another champion, a teenager, Malala Yousafzai who was shot because she wanted an education. My voice is more powerful than any weapon on this Earth. Reporter: She and her father wept as they sat down with the parents of the missing girls. To continue to stand up and speak out loud for them. On social media everyone was speaking for this campaign of bring back our girls. But then it just went down and everyone is silent now. What do you want people back in America, in the united States, to know? What can we do to help? I want them to go back and bring back our kids. Reporter: The girls who escaped still have not returned to school. In fact, they told me they don't want to go back to school until all of their friends are back home safe and sound. Those girls have been missing now for 91 days. David?
