I agree with repentance, but I don't really think that the level of detail is overkill, seems like he just told the story from beginning to end, leaving nothing of consequence out. That's usually how you tell a story. Especially a story where all eyes are on you in a bar over a few hours. I don't think he'd incriminate himself in his home town but being on the other side of the world he could.
It's the nature of the details that are suspicious. Is he really stashing platinum and swiss francs in a Swiss bank? I somehow doubt it. I could believe the box in Dallas but this whole international playboy stuff is like something out of a movie.
Also the private detective thing, I think that would be totally pointless. All a private detective could do is find his current location. And then what? Seems like it wouldn't help much. Didn't people have an address in Texas for him anyway? For all we know he could still be there.
Assuming that BangkokGuy is not Trendon then the whole thing could be true. Trendon told the story to the bar, a lot of it is true, but in true drunk/storytelling mode he embellished the story with a few pounds of bullshit (Swiss bank etc.) to make it more entertaining. With that in mind I can believe that BangkokGuy may have met him. That was a while back so it does not help us much now. I sure wish Goat could have made it to the bar when he was there.
