A bride who was able to walk down the aisle to get married was escorted by the father of the organ donor who made it possible. Five years ago, Daniel Donnelly lost his daughter Heather in a car accident. Heather was an organ donor, and a total stranger to Diana Donnarumma, who received a life-saving small and large intestine transplant from Heather’s body. When Diana reached out to Daniel to thank him for the gift of life, she learned that Heather had died just before her own wedding.
