Insurance Fraud, How to report it? And what will happen to the guy?

Insurance Fraud, How to report it? And what will happen to the guy? This guy who has no life but to mess with other people just made a huge hole in the side of his house. I watched him do it. But I have to live next door to him. So I do not want to tell the cops. Or they will be over there telling him I seen him do it. So I have been dieing to get rid of this jerk. How do I report him to the Insurance company? He just told cops that* in his words:Some black guy, was in his back yard and smashed his wall with a sledge hammer. Now the insurance Company is outside taking pictures and he is telling them the same story. There was never anyone in his back yard. I watched him make the hole. If I turn him into the Insurance company will he finally go to jail? Or what happens?
