I was asked a couple years ago to evaluate a case with the possibility of being called as an expert witness. I declined because I felt there were people more qualified than I was even though I'd just authored the SDI drysuit course. And I wasn't made aware when the case materials were sent that there were autopsy photos in the packet.I went to a DUI rally; my experience was...interesting.
I and a bunch of n00bs (about eight of us all told, including Dad, Mom, 20-ish daughter, and daughter's boyfriend) were sent to a dock, where we stood in the shallows and waited for an instructor to arrive.
The instructor didn't come and didn't come and didn't come, so I got bored and switched into lecture mode. I told the others how the drysuit worked, gave them tips on how to inflate and deflate and maintain buoyancy, instructed them how to route and connect their hoses, and so on.
Finally, the instructor arrived. "Hey, welcome, add air here, let it out here, let's go dive." Splash. The group got waaaaay more out of me than they did the official leader.
So we proceed to dive. Mom couldn't control her buoyancy at all. For about five minutes, she's up, down, up and then rockets downdowndown to 60'. We all go after her. The instructor catches Mom and gets her sorted out...and then does a headcount. We're short one. Daughter is missing.
The viz is crap that day. Ohhh boy...
We beeline for the surface. Daughter is sitting at waterside, out of her drysuit. She got a suit squeeze and bailed about two minutes in, but nobody had noticed.
So yeah...it was interesting.
For reasons I won't go into, that wasn't cool.
The case involved a drysuit try dive where a DM took divers out. Short version is one drowned. It wasn't long after that a number of drysuit try dive days stopped for a while. I'm sure the case settled as I never heard anything else. And with what I had going on in my life at the time, I didn't follow up checking to see.
