Dr. Stephen Reisberg #link#342DMHI and his wife, Jenny Sun-Reisberg #link#715DFHI, vanished in September 1990, during a hike in Kokee State Park, a 4, 000-acre park on the island of Kauai. They were experienced hikers who had left Boston on August 27, to hike in the Tetons before flying to Hawaii. They were scheduled to return home to Boston on September 9 and Jenny was to report back to work on September 14. Ten days later, after not returning to work, the couple were reported missing on September 24. The last person to see the couple was the program director at Kokee Museum of National History in Kokee State Park in Kauai. He's uncertain of the exact date but believes it was after September 9. The program director said the couple studied maps of Mt. Waialeale for over an hour and talked of visiting the summit of the island. The hike takes several days, and he tried to dissuade the couple from making the hike. The mount is described as a vast wilderness with almost no trails and cliffs with straight drops of nearly 4, 000 feet. Two weeks after they were last seen, their rental car was found at the Puu O Kila Lookout in Kokee State Park. Inside the vehicle were the couple's backpacks, tents, and suitcases packed for the flight home to Boston, possibly suggesting the couple had intended nothing more than a short day hike. For two weeks, bloodhounds, helicopters, law enforcement, and experienced hikers searched the park for the couple. All that turned up was a scarf similar to one Jenny had packed in her suitcase and a report of a hiker who claimed to have heard the sound of a woman moaning 10 days prior.
