Well, once again I'm wobbling on the fence. You do all make good points. This is one reason why people shouldn't be so darn QUIET during situations such as these. The less info they put out, the more speculation and suspicion arises. Don't they know this?? I just don't get it. This goes for both family and LE. It can't be good for anyone to have all these questions floating around in the air. And it's perfectly natural for people like us, and people in her community, to wonder and to want to figure things out and fill in the holes. The speculation is gonna happen. So why not make every effort to put all the correct information out there? Then maybe, just MAYBE, someone can come up with a good idea of where to find her. [[Family, if you are reading here, please consider this!!!]]
As for the gas... I'm a bit confused, as well, about why that was even brought up. I wonder if the cops asked GR this question, and so he felt it must be an important tidbit and that's why he put it in his post. If cops asked before the car was found, it would determine whether or not she might be stopping for gas, how far she'd be able to travel, etc. If it was after the car was found, it would determine if she'd driven around town a lot before going missing, or went straight from her house to where the car was left. And if the tank was pretty much full when the car was found, they'd want to know whether it was filled up by Jennifer for the purpose of getting out of dodge, so to speak. So yeah, I think GR just picked up on it during police questioning, and included it in his post. Just a guess, of course.
