The Sheriff did seem uncomfortable talking about possible store video & later even make a joke to that effect, but I find it hard to believe somewhat. As a small business owner in a rural area, I have it. It's cheap these days, whether you have a convenience store of selling gas...not having it can be expensive for many reasons & situations where you could be libel & not just employee theft. Also the Sheriff implied what he sent to the FBI he didn't want to talk about evidence. Maybe if there was video it was included??? But, if little DeOrr was on a store video or gas station, wouldn't you be 100% sure? He's sure the receipt matches up though. But perhaps a video / picture / sighting could be fraudulent or maybe there is no sighting? I find it strange, especially poo-pooing a stranger giving a creepy-look, as if they didn't investigate that lol. Of course they did in that tiny town IMO!
ETA - Yes, I think they have a theory.
