Do you know what happened to Jo Lynn Thomas? In Honolulu, on the night of May 14, 1994, Jo Lynn Thomas, a 30-year-old woman, vanished from the last place she was known to be seen. 
According to police, she was last seen in Waikīkī the day before her body was found, and the person who reported being with her at that final moment was her husband, Robert. 
By May 15, 1994, she was discovered dead on Diamond Head Road, a roadway that runs along the slopes and coastal edge near Diamond Head’s crater and the
neighborhoods east of Waikīkī. The case was treated as a murder, but the public trail of confirmed facts quickly narrows after that grim discovery. 
Police records made public in the department’s cold-case listing state that Robert was arrested in connection with the killing, yet he was never charged. No other suspects are named in that public summary, and no trial or conviction is described there, leaving the case suspended between an early arrest and the absence of formal prosecution.
