Random Thoughts:
There are other articles out about the gov's award (just google for the gov's name and holly's name the reward) that say it's for the rescue and return of Holly Bobo - not just an award for the arrest of the kidnapper. I don't think we can really know reward terms until we read them...so IMO, I wouldn't read too much into articles regarding the reward.
The fact that the Gov's office was easily persuaded that a BIG reward in this case would be extremely helpful did say something to me. IMO, they had a feeling that compatriates of the abductor would have knowledge and would help the investigation so long as they knew there was some big money out there to do it for. It's as if the Gov's office is willing to pay an information ransom to specific members of tight community.
