Tomoko Ioh, 41, disappeared from Kailua-Kona, Hawaii on the morning of Sunday, October 18, 2009. She left her home about 10:30 a.m., telling family she would be back in thirty minutes to an hour, driving a green and silver 1999 Suzuki Grand Vitara. When she did not return, concern grew and later that evening her vehicle was found abandoned at Wawaloli Beach Park near the Natural Energy Laboratory of Hawaii.

The car and items inside appeared undisturbed. Police and fire crews mounted searches along the rugged coastline known for strong currents; cadaver dogs were used and at one point behaved unusually near a local fish farm, but no sign of Tomoko was found. A south swell prevented divers from searching underwater caves. Family said she was a competent swimmer who liked the ocean and that she had a medical condition that might require medication.

Does anyone who lived or worked around Wawaloli Beach Park in October 2009 recall seeing Tomoko, her vehicle, or anything unusual that day?
