Ok, close family member resource, a diver with only several dives several years ago. I asked enough questions I felt pretty intrusive but nowhere near all of my own questions, nor had answers to all I asked. This is just relaying what I was told.
He was boat with surface support following bubbles (they just stopped early into the dive) scuba, collecting with the fence net thing and accompanied. Both long experience divers, have ties to several businesses here and Oahu. Unknown how became separated and/or time before search began. It was very rough out.
Unable to locate him that day, was located "exactly where" lost the next day. Found with all gear intact and in place. His mask was still on (with no blood visible) when this family member first saw him just after recovered. Was (as usual) heavily weighted. Found resting on R side with R arm extended overhead (parallel to body) appeared relaxed, no evidence of panic noted. Was not entangled in net (?s) and had just unhooked them.
Some distress occurred when recovering - reason unclear but it was very rough and out of air were mentioned - so his tank was removed and left behind. Working on recovering tank, depth was indicated a possible point of concern.
Autopsy done >72 hrs after
?missing or recovered?
and thought to be a mistake
.(is there a time limit for effective cause of death determination for diving?). Result of autopsy is not known.
My sincere condolence to family and friends.
