They are in Illinois as well but finding the info you need is a different story.
I've used Missouri's "casenet" and it's a handy tool but it's fairly new and not every county, or city is on line yet and among those that are, there is too much incomplete information or none at all in certain cases. Scott, Cape Girardeau, Stoddard, New madrid and Mississippi counties are especially bad.
Agreed they don’t have everything - especially older convictions but her latest (prostitution and heroin manufacturing/selling/whatever) were in about 2008 and 2009. I bet even her older ones should be on there.
I think I’ll look and see if I can find her.
