"She never put herself before anyone. She always had a smile on her face," friend Victoria Campbell told WSOC-TV. "If something was bothering you and she knew about it, she was right there to give you a hug and give you all of her support and cheer you up. She was smart and beautiful, inside and out."

Campbell said a softball injury led to an epilepsy diagnosis for Davis and that her parents said she became a tissue donor after she was removed from life support Sunday morning.
