Did something go wrong with his business? Not sure what advice to offer, I do think a call to the authorities might help, but which ones? Local cops or state? A lot of that would depend on his connections. I've got an acquaintance dealing with issues with a neighbor because the neighbor's sister is the town's assistant police chief and shields him from the consequences of his actions. They are trying to work through state authorities because of it, which is still proving difficult.
