I can answer to the question as to the pulse here in Midlothian as the days go by without an arrest.
On one hand, we are confident it'll come any day now. On the other hand, there's that fear that LE has nothing hard right now to make an arrest and that's terrifying. <modsnip> But LE is certainly digging deeper into some people. As with the Teresa Sievers' case, it took 3 months for the first arrest. Granted, they didn't have video as in this case, but it does take some leg work and most seem to understand that. In general, I will say that it does feel a little eerie around town, especially when it's dark out.
