It's been over six years since my interest in this case led me to dig around and find out as much as I could about Bayard Cousins and La Belle Chasse John Doe. After a couple of hopeful conversations with the case agent in VA Beach (where I was living at the time), I never heard back from her. I know she had been in contact with Bayard's then living family, a sister and an aunt or cousin, but I have no idea if she discussed this John Doe with them. However, if they have googled his name they will find this thread.
I don't remember everything I was able to find out at the time, but I do remember being told all coroner records were destroyed by Katrina. I also remember that some of the Mothe family members and employees were still on board who would have been there when they kept him available for viewing for a few months, as folks came from all over trying to identify him as a missing loved one. Possibly, with all that attention, such an employee might have remembered where John Doe was buried, if it was not available in the records.
With as much as enthusiasm as people have had for this case, but the constant dead ends, we are left to wonder if the disconnect lies with apathy from local authorities, or if the information is just lost forever. Maybe the only avenue to really push for answers and bring public attention would be an investigative journalist covering it for a show or something.
