Stewart died in January 2017 in an incident off the Florida Keys while filming on a wreck during the making of Sharkwater Extinction, as reported on Divernet.
Completed by his company Sharkwater Productions after his death, the documentary includes undercover filming in parts of the world such as Costa Rica, Panama, West Africa, Spain and France to expose the illegal shark-fin industry and the connections to organised crime and political corruption behind it.
In the wake of Stewart’s death his family filed wrongful-death lawsuits against his diving instructor, who accompanied the inexperienced rebreather-diver on three 70m wreck-dives in a single day, the instructor’s wife as co-owner of their dive-company, the company itself and the boat-operator.
The suits have yet to be heard, and the US Coast Guard report on the fatality has yet to be made public.
