Osage Beach, Mo. – Authorities are searching for a missing Chicago man in a part of the Lake of the Ozarks known as Party Cove.
The man disappeared Saturday while diving to search for two pairs of sunglasses. He found the first pair and then went under water again. A witness says he never resurfaced.
The man had been partying with about five friends in the rowdiest part of the cove known as "the gauntlet."
The Water Patrol estimated as many as 2,500 boats were anchored in the area when the man disappeared.
Authorities say the large number of boaters had complicated the search for the missing man.
They're trying to determine whether the man drowned or swam to another boat without telling his friends.
