Kenan Knieriem, 58, an investment adviser from Honolulu and senior vice president for investments at Merrill Lynch, disappeared from the Pacific Ocean on September 24, 2011. He had been on a celebratory fishing trip about 13 miles south of Waikiki two weeks after his wedding. While attempting to gaff a large mahimahi, he lost his footing and fell overboard. Witnesses reported he was seen briefly in the water, reportedly unresponsive, before submerging and vanishing.

Two friends, Rosina Ho and Amalia Johles, entered the water and his wife, Debi Ozawa, tried to maneuver the boat toward him, but strong currents and rough seas prevented a successful rescue. The U.S. Coast Guard conducted a ten-hour search covering 117 square miles with no sign of Knieriem. Investigators concluded the available eyewitness accounts pointed to a tragic accident at sea, and no trace was ever found.

If anyone was on or near the water south of Waikiki that day or has information about the search, please share what is known.
