Antero Leinonen, age 46, vanished from Waimea Beach Park on Oahu’s North Shore on March 13, 1990. Visiting Hawaii with his wife, he was standing along the shoreline in white and blue swim shorts and was seen diving into heavy incoming waves; he never resurfaced. His wife raised the alarm and an extensive search of the ocean and coastline was mounted, but search teams found no sign of him and the operation was eventually called off. The couple’s rental Toyota Corolla wagon was left at the beach and later returned to the rental agency. The Honolulu Police Department’s investigation concluded he was lost to the sea after diving into the waves, and no further evidence or leads have been reported.

Did anyone who was at Waimea Bay that day or who has knowledge of the events have information to share?
