Diane Yayoe Suzuki was a 19-year-old University of Hawaii at Manoa student and part-time children’s dance instructor who vanished from the Rosalie Woodson Institute of Dance in Aiea on July 6, 1985. Her class ended around 3:00 p.m., and by 3:15 p.m., when a friend arrived, she was gone. Her purse, keys, and car were left at the studio.

Blood was later found in the studio bathroom and investigators reclassified the case as a homicide. The Honolulu Police Department used luminol in the investigation. A photographer who worked at the studio reportedly failed a polygraph test and was the focus of later investigative attention; a grand jury reviewed the matter in the early 1990s but did not return an indictment. Diane’s body has never been found. Her family held a memorial service; her parents have since died.

Anyone who knew Diane, attended the studio in 1985, or has information that could help resolve her disappearance is asked to come forward.
