The Hawaiʻi Police Department is looking for 58-year-old Charles Kanoe Reyes, of Kapaau, who has been reported as missing.
Officials say Reyes was last seen at home by family members on Saturday night before leaving to the shoreline to catch crab and pick ʻopihi.
His vehicle, a white Mazda Protégé sedan, was located by family members on Sunday morning, parked at a gate at the north end of Union Mill Road.
Police say beyond the gate is a trail leading to the shoreline.
A backpack, identified by family members as belonging to Reyes, was recovered by HPD Officers from a cliff above the rocky shoreline area not far from the end of the trail.
On Sunday, the Hawai`i County Fire Department attempted a retrieval of a body in the same area that ultimately could not be recovered after a shark reportedly submerged it. The identity of that body has not been confirmed.
Police ask anyone who may have information on the case to call Officer Dayton Tagaca at (808) 889-6540.
