How about Molly Bish from small town Warren, MA (population 1,535 as of 2007, smaller back in 2000 when she vanished)? Her case was very publicized, I remember seeing her pictures on magazine covers at the grocery store. Very small town, smaller than Chisholm population 5,000) , but her parents worked so hard to not only bring attention to the case, but to keep it alive throughout the years until her remains were found.
Or Sabrina Aisenburg, from Valrico, FL, population about 7,000? I've see her story on 48 hours, along with at the very least a news article written on the anniversary of when she went missing. There's many out there. St. Joseph, MN has population of 6534, and missing boy Jacob Wetterling has gotten much media attention.
And it doesn't matter if the media is camping out, staying in hotels to report stories, usually they don't unless whitney houston died so sad stuff like that makes the news before our missing children). I'm just weary of her parent's efforts in the search for her, they could at least keep her case alive and not forgotten.
And there's many children who go missing in bigger cities who don't get publicity, where you live may have something to do with how much attention a case gets, but not that much. Examples Erin Kay Pospisil from Cedar Rapids IA, pop over 423,353 or Jahi Turner missing from San Diego, CA?
When something happens in a small town, usually its more publicized since not much happens there to begin with, so child abduction would be a big deal. In bigger cities, like Chicago, Los Angeles or Minneapolis, there's so much crime already, it's swept under the rugs.
Not trying to argue with you, just stating my opinion.
