It's a mystery that has been nearly eight years in the making.
In October of 2005, two contractors discovered a man's body at Ford Island.
"We understand he could have died anywhere along the perimeter of Pearl Harbor and eventually floated to this spot," said Phil Camero of the Naval Criminal Investigative Service.
When investigators found the body, it was so badly decomposed, they didn't have much to go on. In fact, they didn't have a description until now.
"With all this new information of his possible age of 45, Caucasian male, walking with a limp and with a shoulder limp, somebody may recognize him," said Sgt. Kim Buffett of CrimeStoppers.
The Honolulu Police Department is helping the NCIS to reopen this cold case. They released photos Monday of the sandals, watch and size 40 jeans the man was wearing.
Police still don't know exactly how he died. However, thanks to forensic analysis, they know he passed away on land before somehow ending up in the water.
"At this stage of the investigation, we have not ruled out foul play," said Camero. "But, likewise, we have not ruled out accidental death or death by natural causes."
Federal authorities believe the man was homeless. They hope any help in identifying this man will solve the mystery behind his death and allow federal investigators to lay this case to rest.
