Coming from a small town as well, I can't imagine the police are well equipped for this type of crime, not knocking them, but I'm also going to throw in scared as well. If town's people aren't talking, I'm assuming they are afraid, that gas station, at least for me, that is some place I wouldn't go. Unless I desperately needed gas, or desperately needed other things being sold there. I thought this was going to be easily solved in the beginning, now, I do not. Could some of the people at the gas station, the owner, and others milling around, for lack of better words, basically own the town? Don't go against us, sort of thing? I know living in a small town, there is nothing going on, and it would be easy to fall into stuff you may not normally do? Not suggesting Jessica was like that, but I'm sure the poor girl was bored, and happy to go to her job, just for a change.
