I did watch the NAT GEO show.  The people they were investigating for perhaps murdering Cody were so squirrely and acted so suspicious I thought one of them were responsible for his disappearance.  I'm so relieved for the parents that they found their son.  I don't know if it helps that he wasn't murdered.  At least we can assume he died quickly and wasn't beaten or tortured to get his money.  I am sorry they didn't find Cody alive.  Rest In Peace Cody.
