Amid the unspeakable grief of losing a child on Christmas Eve, a Central California couple has made the decision to donate their daughter's organs so other parents can avoid the kind of pain they are experiencing. Manteca resident Tony Izzo tells The Modesto Bee that doctors at UC Davis Medical Center yesterday were harvesting the heart and other organs from the body of his 9-year-old daughter, Mariah. The girl suffered catastrophic brain injuries on Monday while riding in a small SUV being driven by her aunt. A larger SUV slammed into the vehicle while it was stopped at a red light. Her father says her organs will go to at least five other people.
