The latest story is that he canoed all the way to Panama and once there disposed of it so it came back via the gulf stream. He was only reported missing, not dead.
I would hope the couple are made to pay back every penny the police are spending on this case! Can't see it though - they'll probably get out of it by declaring themselves bankrupt!
As their actions were all down to lies & pure greed, I hope they end up on their uppers!
