I recall the original story when the relatives he came down with said he had been despondent due to business downturns. I have heard of many suicides of people who submerge themselves in the water with a car, and they usually have a large amount of pills or a gun to help facilitate that they stay down. The original stories speculated that the man was murdered and the car off the island, but I was only surprised it took so long to solve this mystery, as there are so many scuba divers in St. Maarten. Forensic scientists could probably determine if it was suicide or homicide. I know in the cases we have seen in our town for the same type of death -- it is always they have been dealing with overwhelming depression.
