Call the police and file a report. Your phone should have the number. See if it can be traced. You didn't say you knew who it was. Is there more to this story? Make sure your wife has a carry permit and know how to shoot. Get a good big dog, not a mean one but one that knows what protect means. Have him slapped with a stalking charge. If you're found guilty of stalking, I think it becomes illegal for you to own guns. Good Luck!
