It appears that the missing man or his body has not been found yet because I can't find any newer articles. He disappeared on the hottest day of the year (June 20), and they found his car on July 1. Strange. Even if nobody reported him missing, seems that a car sitting around without a current permit would attract attention, especially considering the hot weather, so I'm guessing the vehicle was in a location that is rarely visited by the park staff. There aren't many details released. It's unclear whether the camera saw him (or somebody else) driving his vehicle into the park and whether he told anybody that he was going hiking.
