I met Jerry a few years ago, but didn’t know him other than that one quick meeting. I never dove with him but knew he was gonzo for diving. I saw a news story today (video) in which his family said they were told his air was turned off. Perhaps there is more to the story, but regardless my first question was why, if he were at the surface calling for help, did he sink again. Ditching weights or establishing buoyancy would have at least resulted in a body at the surface that could be treated and/or resuscitated. It’ll be interesting to see what the investigation turns up.
