Yes, he did, and tried to cash in on it AND charge back for their bummer trip.

"Tina's father claimed Watson had asked his daughter to increase her life insurance and make him the sole beneficiary shortly before their wedding. The insurance company confirmed Watson had twice emailed questions about its dive insurance policies before the honeymoon and had asked about her insurance shortly after Tina's death. Watson also claimed hundreds of thousands of dollars from a travel insurance policy."
"In March 2005, Watson launched legal action in Alabama's Jefferson County Circuit Court to recoup the cost of their trip after the travel insurance company refused a payout. He was seeking $45,000 for the accidental death plus compensation for trip interruption, medical expenses, phone calls, taxi fares, fees for extra credit card statements and unspecified punitive damages for mental and emotional anguish."
Real piece of work. I think he was the text book case for GG - he must have missed the US indictment. The big difference here, no body.
