Roque Rivera, 75, was last seen on Easter Sunday 2008 near the Dole Cannery in Hawaii Kai. His Ford Explorer was found in the area, but there were no confirmed sightings that established where he went after that. Rivera was described as 5 feet 7 inches and about 165 pounds, wearing a blue United Airlines baseball cap, a blue shirt with white stripes, and blue jeans when he disappeared.

A close friend who met Rivera every Monday to hike raised the alarm after being unable to reach him; Rivera’s son came from San Francisco to help search and coordinate with Honolulu Police. Family and friends checked beaches, homeless shelters, and his church. The son feared his father might be living homeless or could have had an undiagnosed medical problem such as Alzheimer’s, though no diagnosis had been made.

Anyone who knew Rivera, his routines, or who may have seen a Ford Explorer near the Dole Cannery on Easter Sunday 2008 is asked to share information with Honolulu Police.
