Found this article from June of this year:
“He is a son, brother and high school valedictorian, but people who hear his name know August Reiger as the Oklahoma man who vanished on a trail 3,000 miles south of home.

No clues were left. Reiger's disappearance sparked fruitless searches, unconfirmed sightings and armchair theories.
He hiked ahead of his younger brother and his parents, Chris and Randa Reiger, along a trail that takes a few hours to loop.
About 10 minutes behind him, when the family reached a pavilion at the top of the mountain, Reiger was gone.

‘The lack of information regarding this case is frustrating,’ said Mike Nance, a retired Tulsa cop who serves as an administrator overseeing Region 4 of the National Missing and Unidentified Persons System, which includes Oklahoma, Arkansas, Louisiana, Mississippi and Texas.

After his retirement, Nance worked as a cold case and missing person investigator for an Oklahoma district attorney's office in the northeast part of the state.
Evidence of a kidnapping is lacking, Nance said. Several questions remain. What was Reiger's state of mind when he disappeared? What was the family dynamic?
Without having been to the location,
Nance wants to know more about the experience level of those who were looking for Reiger.
‘I question the search,’ he said. ‘I would like to see the search plan and extent of the search.
My belief is that August's body is in close proximity to the hiking trail and that some tragic accident occurred that caused him to perish.’” (BBM)
Five years later, Oklahoma City man August Reiger still missing
I didn’t realize that the rest of the family was “about 10 minutes behind him.” Somehow I always got the impression that they (his brother, especially, IIRC) were closer to August.
I do think that Mr. Nance is correct about what likely happened to August and the probable location of his remains. So very sad.
