I believe this story. I googled the coordinates. It matches the description exactly. A long drive so far in the middle of nowhere, that street view ends several miles away, and that's from 16 years ago. It's almost due west of Boulder Colorado, too. The place looks sketchy.

As for the rest of it, there's too much detail and too little gloating for this to be reasonably fake. "The devil is in the details," ie the more details, the easier it is to disprove, and thus catch the lie. The lack of gloating tells me that they aren't narcissistic enough to fake this detailed of a story for the attention.

The realism is never broken. The style doesn't change. It comes across as a broken man spilling his darkest secrets because it doesn't matter what happens to him anymore. A last ditch effort to regain morality for its own merit. An anti-hero through and through.
