If i had to bet money on the ping, I would bet it was in the house more than side of the road. That's the safest bet in my mind
There's nothing to say that Sara wasn't brought back to a house near her home, somewhere closer to the ping. But since there haven't been further abductions of young women in Fairmont over the last year, I tend not to give abduction much weight.
The reward being offered now seems like an attempt to get someone to turn on someone. After all, the FBI did say they think someone knows where Sara is and how could someone not know really after all this time. But will the news of the reward reach that someone?
