Disappeared - S04E06: Mystery on Lake Seminole

Jerry Michael Williams is a successful businessman in Tallahassee when he goes on a solo duck-hunting trip to Lake Seminole and disappears. Searchers find his truck, his boat, and his shotgun, but they can’t find Mike. It’s assumed he’s become the victim of a tragic boating accident, but officials are perplexed that his body hasn’t surfaced, because that would make Mike the only drowning victim on the lake who has never come up. Lake Seminole is infested with alligators, and a frightening theory is raised of what might have happened to Mike. Searchers tell his mother that alligators may have eaten him. She doesn't buy that explanation. While she hopes her son is alive, she begins to think he may have been the victim of murder, not misadventure.
