Thursday’s funeral service in Fort Wayne was bittersweet — a joyful remembrance of who Caleb Swanigan was, and a reminder that he is gone far too soon. He died of natural causes June 20 at the age of 25. “He was a gentle giant — not because of his height, but because his heart was so big,” said Susan Thomas, a friend who was one of the first people to meet Swanigan when he came to Fort Wayne before his eighth-grade year. “He had friends everywhere. People were drawn to him.”
