It just occurred to me that maybe the FBI knew where the body was all along. They just didn't "FIND" it so they would have more time to get the goods on CONDIT for other things. Sort of give him enough rope to hang himself..... .....Now that's a thought!
It would explain why the "grid search" MISSED the body.
I do believe Chandra was "blackmailing him" The big news could have something to do with that. Wasn't there talk at one time that Chandra's "boyfriend" was an FBI guy? She certainly wanted to work for the FBI and may have seen herself as a "sleuth"!
Post 633 - I think Chandra wasn't found until now because of plain old incompetence. They didn't search that area because it "was too remote". DUH.
Seems you would start with the most remote areas and work your way in to civilization.
