A young man is lucky to be alive after doctors say he was internally decapitated. Brock Meister was rushed to a local trauma center in South Bend, Indiana. His doctor says the 22-year-old's injuries were extensive and life-threatening. Dr. Kashif Shaikh of Memorial Hospital says he wasn't sure whether Meister would ever walk again, but he appears to be defying the odds.
