That Lost Civil War Gold

I have followed this story somewhat for a while. I really think the treasure hunter was tricked. They told him there was nothing there and then came in the night and excavated it. The whole thing was very suspect. I think he was cheated. They could have at least let him have the glory and given him a finder's reward. I hope the truth comes out at some point.
 
Well that doesn't make sense. Why would the FBI lie about finding historical artifacts? I think we can trust the FBI not to be involved in some kind of conspiracy or cover up!
It really did look like they excavated the area under clandestine means. That gold was not an artifact but worth a lot of money. Someone wanted a fortune.
