Lisa Au was 19 when she vanished on a stormy night in January 1982 after leaving a Makiki apartment where she had spent the evening with her boyfriend, University of Hawaiʻi student Doug Holmes. The two walked to their cars near midnight, said goodnight, and separated; Lisa called to say she was on her way home and was never seen alive again.

Her Toyota was later found abandoned in Kailua with water pooled inside and the driver’s seat soaked, yet her purse, keys, and wallet remained dry and her driver’s license and vehicle registration were missing. Ten days after she disappeared a jogger found her nude, decomposed body in a ravine on the slopes of Tantalus in the Makiki area; decomposition prevented a definitive cause of death, and investigators concluded she had been killed and left there.

Witnesses later reported a vehicle following her with blue flashing lights, suggesting she may have pulled over for someone impersonating authority; rumors of possible police involvement circulated but no arrest has been announced. A grand jury reviewed evidence but reached no decision before disbanding in 1984. Does anyone have information about Lisa’s last movements or the blue-flashing vehicle that could help finally resolve this case?
