Jack Lord passed away on January 21, 1998. Following his "retirement" from Five-O, he lived a Greta Garbo-like existence in a multimillion dollar waterfront condominium in Honolulu. There were unconfirmed reports during his last few years in the tabloid media, often accompanied by out-of-date pictures, which suggested he was suffering from Alzheimer's disease. These rumours were denied by his wife Marie and others who knew him. (Click here to see an interview with Marie Lord, reflecting on Jack Lord's later life, taken at the 1999 Five-O convention. (This does not currently work properly, I will fix it eventually.) On the other hand, the general consensus seemed to be that Lord was ill with some medical condition. (See comments by James MacArthur in the Honolulu Star-Bulletin.) An interesting theory regarding Lord's health was posted over 20 years ago in the Usenet newsgroup alt.fan.hawaii-five-o by Five-O expert Karen Rhodes.

After Lord's passing, he was honored with a sculpted bust celebrating the actor's life and career on stage and screen, both movies and TV, outside the Macy's at Honolulu's Kahala Mall. It was created by Lynn Weller Liverton and dedicated in 2004. Lord and his wife lived in the area, and could occasionally be seen at the mall. In 2018, long-time Five-O fan Ringfire visited this memorial, and sent along these pictures: #1, #2, #3, #4, #5.
