BERMAN: A stunning story of survival. A teenage girl is alive after the plane she was traveling in with her grandparents crashed in the mountains of Washington State. 16-year-old Autumn Veatch told local law enforcement she waited on rescuers for a day and slept by a river.</s>BOLDUAN: Before making her way to a highway where she was picked up and taken to a store where she -- where help was called. She's now at a hospital being treated for dehydration and muscle damage, a disorder she developed there. The sheriff says it doesn't sound like her grandparents survived. Joining us is Rick LeDuc, the owner of the store where Autumn ended up. He was one of the first people to see her after she was found alive. Rick, are you there?</s>RICK LEDUC, STORE OWNER (voice-over): I am.</s>BOLDUAN: Great, thank you so much for joining us. This is an amazing story of survival. You saw this girl. You saw this all firsthand. What happened? What did Autumn look like when she arrived at your store?</s>LEDUC: She was brought into the store by two gentlemen who picked her up on highway 20. Brought her in, at that point she relayed what had happened and that she has been in a terrible accident, had been out for the last three days. Two days out to get help. At that point, 911 was called and the sheriff's department and the rescue service were -- the EMS process was started. At that point, just tried to take care of what she needed.</s>BERMAN: How did she look? How did she look?</s>LEDUC: Remarkably, she looked quite good for somebody who's gone through an incredible ordeal and hiking through very difficult country, mountainous terrain. And where she was all trail so she had to beat through the brush, it sounds like, getting down to where she was found.</s>BOLDUAN: It's just amazing. We're seeing video of that. It's just amazing. Now she's recovering in the hospital. Rick, well, probably you helped in trying to get her to safety and get her the help she needed. Thank you --
