EAST MEADOW, N.Y. (AP) — A teenager paralyzed after he dove into a sand bar at a Long Island beach is thankful for his doctors and therapists who helped him walk again. Nico Fiorello took some steps unaided on Wednesday at a news conference at Nassau University Medical Center. The 17-year-old was hurt at Jones Beach in May, when he dove into the water and hit a sand bar. He underwent two surgeries, which included having a metal plate inserted into his spine.
