About a month ago my neighbor has been accusing us of stealing his checks from the mailbox and going to cash them at the exact place he goes to. Also that we somehow manage to change address of where his checks arrive. He has been telling neighbors that he has gone to the cashing place and manager showed him the video with myself changing the checks. As of now when i confronted him he didn't accuse me directly but just said that somebody has been stealing his checks. Two days ago he came to our home and talked to the renter; pretty much told her to watch out because he said we had been the one's stealing. He also said that in a couple of days cops would come and arrest us for doing so. my question is do I have a case, what should i do in regards to this?
