Bryan was born in Oahu, Hawaii, the son of Ben and Betty Adona. He was employed as a mechanic for Aloha Airlines, and engaged to marry Dayna Kuboi. When a car accident left him with weak and injured legs, he took up body boarding to stay in shape because it didn't require him to stand or run. He loved the relief that being in the water gave to his aching feet and legs, and he became an experienced body boarder. He went body boarding alone at one of his favorite spots - a little surf break called the Leftovers, which is west of Waimea Bay, Oahu, Hawaii. He'd body boarded alone before, and he would always put on his small fins, affix the key to his Ford Ranger to the head of the surfing leash that was connected to his body board, and then attach the leash to his ankle. The swells at Leftovers that day were running from about three to five feet high. Also on the Lefovers beach that day was surfer Danny Titilah. Danny, and a surfing buddy, saw Adona paddle out about 500 feet toward Kipa Rock, but the two buddies elected to surf a break closer to shore. On his way out, at around 200 feet from shore, Danny noticed a large brownish-beige shape break the water briefly and then duck back under. Later, looking back toward shore, he saw the shape again. Danny was uncertain of what it was and was too far away from Adona to say anything to him about it. So, Danny continued to surf with his friend, and then left the beach. Unfortunately, Danny was the last person to see Bryan alive. When Adona didn't come home that evening, his fiancée, Dayna Kuboi, called around looking for him. A friend of Adona's went to Leftovers where he found his truck but no sign of Bryan. The police were called and a search that included fire and rescue workers began. They walked up and down the coastline for hours looking for any evidence of Bryan. At the same time, a fire department helicopter buzzed over the moonlit ocean waters until 2:00 AM but there was no sign of Bryan. The next morning, soon after North Shore lifeguard Kerry Atwood reported for work, he noticed a body board lying on the beach at Waimea Bay. When he picked it up, he immediately noticed a huge crescent-shaped piece missing from the left front side of the board. A Ford Ranger key was attached to the leash. It was Bryan's board. He is thought to have died as a result of a shark attack. The 16-inch crescent shape indicated that it was a 12-13 foot Tiger shark. Bryan's parents came to Waimea Bay from their residence in Pearl City, and searched for Bryan 40 days straight. But in addition to the body board, only his left swim fin was ever found. Bryan was just taken, and has never been found. His family erected a small memorial with a cross on the beach at Leftovers and, Bryan's mother, Betty, visited the spot once a week for an entire year.
