There is a couple in town that has been indicted on all sorts of things- medicare/insurance fraud, witness tampering, etc. Nothing violent but their business was raided by the FBI and all sorts of interesting things. Most recently there have been several boxes of files missing.
They happen to own the house across the street, but they have never lived there. In the past 4 years I can count on one hand the number of times we've even seen a car.
Today there have been 2 separate cars with 2 separate men at the house. I wrote down license plates.
