What is the chance that North Conway does not want to make a big deal out of this case, because of tourism? I'm guessing there are many people in the area who have a lot of influence (business owners?) who do not want to worry about scaring off tourists and losing money because they think there is a crazed abductor/possible murderer driving around. I do not think they would like the case all over the media, help find Abigail because someone abducted her, we have no idea who did it, etc.
From what I've seen, there's no chance of that at all. I've read that Settlers' Green isn't allowing posters/pamphlets to be posted, but I think that's a rule coming from their corporate headquarters. Lots of the local businesses in the town have Abby posters up.
