In "Cocoon" (Pilot), Intelligence called and told Five-0 that intelligence agent Hennessey's body had been recovered from the waters of Hanauma Bay.
McGarrett sped out to Hanauma in the two-door Mercury Marquis and down this lane bordered by a lava rock wall. He came to a halt on the roundabout seen at the bottom and ran down to the water's edge, where an HPD officer and a beach goer explained how they had found Hennessey's body.
The scene still looks the same -- except for the presence of a white pickup truck, instead of a black Mercury, that is. Here, we see the beach at Hanauma Bay as it appeared in April 2008. Photographs posted over the past few weeks show how it appears today.
