I wonder if the wife received any as requested? Were there parameters set as to how the info would need to be given, and what results it may have to yield before payout, and how much payout depending on which info?
Generally it's for information leading to the discovery of the body or the apprehension of the suspects. Given that an RCMP on patrol spotted the car and apprehended the suspects and that supposedly CB has told investigators where they dumped the body, I don't think any will be paid out.
