The insurance policy seems more like his apology to his wife, and a dare as to whether she will get the death certificate and file the claim. Upthread, we read that investigators knew early on that his "death" was a scam. They told his wife, and asked her to keep quiet - even from family. She did.
Meanwhile ... the investigation continued. I'm curious whether the only reason that this has become public is because investigators want proof of life. They can't find him.
His family wants him to know that they miss him, they love him, and he is welcome home at any time. The gig is up. He got caught falsifying a kayak drowning. There are no charges at this time.
If he is a decent man, he'll step out, tell his family and investigators that he is okay, and it's all over except the bill (S&R cost). If he's a decent man and doesn't step forward, chances are he's unable. Proof of life is needed.
