Yeah, take him fishing. Shut the boat off in the middle of the lake just before sunrise, hopefully a little fog hanging around and casually ask him if he thinks anybody would pay any attention to a muffled scream and the splash of a body with a couple cinder blocks chained to it. THEN tell him it is your deepest hope that your little girl never be hurt by an irresponsible action of the man she obviously loves. That's why fishermen are so secretive about their favorite sweet spots.
