Good to see you're still here Palladin, Have Gun Will Travel. I'm a long time diver and I do a lot of underwater photography still. Picture was taken from too far away no matter what she was trying to capture and with no strobe so, there is not much detail. BUT! It is a mile off of the Marriott so that cant be overlooked. After 5 years a body dumped much further out and heavily weighted could easily have deteriorated to the point that it separated from its weights and drifted closer with the tide. Wont know unless the F.B.I. goes down there and takes a look.
Remember what Paulus said: " No body no case."
