In the Northwest, people get reported missing all the time. This is because it is easy to get into the sticks if you live in a neighborhood that borders a green way. Most of those who do go missing are endangered youths or the elderly with dementia related illnesses. You can probably toss those crime data points out when doing neighborhood comparisons (e.g., comping a neighborhood).
