The carcass of the Gambo was reported to have been discovered by 15-year-old Owen Burnham and his family on the morning of June 12, 1983. Owen, a wildlife enthusiast, decided to take measurements and then make sketches since he did not have a camera at the time. According to later testimony, he did not think to take a sample until after he realized he could not identify it in any books. According to Owen, local villagers called it a "dolphin", but that was likely only because of the superficial similarity. "Gambo" has been connected to many sporadic reports of crocodile-like sea serpents.
