Jenny Sun-reisberg, 28, and her husband Dr. Stephen Reisberg, 34, were last seen in late summer 1990 after a trip through the Tetons and San Francisco to Kauai. The couple left Massachusetts on August 27, 1990, planned to return September 9 but extended their stay, and were last confirmed at Kokee State Park, where they studied maps and spoke of attempting the difficult, trail-sparse climb of Mount Waialeale.

Their rental car was found at the Pu O Kila lookout about two weeks after a Harvard professor reported them missing on September 24. The car contained backpacks, tents, and suitcases, suggesting only a short hike was intended. A search of the park produced little; a scarf was recovered but not definitively identified as Jenny’s.

Theories mentioned over time include a fatal accident on the hazardous route, possible foul play linked to nearby marijuana plantations and violent incidents that year, and unproven speculation that the couple staged their disappearance. Does anyone have reliable memories from Kokee State Park in late summer 1990 or information that could help clarify what happened to Jenny and Stephen?
