Straits of Mackinac diver death

Accident reports take years or more and hardly ever get released to the public, presumably it's better for all the parties involved.

If you want to understand how most of these happen read DAN's annual report. Spoiler, medical issues or diving beyond there skills or training. I believe you have to be a member to download it, I stopped reading them. Sometimes details show up on TheDecoStop under Accidents. It can be a lot of armchair detectives guessing but if you can get to the story of the buddy that survived or actual witnesses speaking that tell a clear story it can be difficult to read (I sometimes find myself shaking because it's close to what I've seen or done only it didn't go bad for me)

I don't know that I ever 'learned' anything from the 100's I've read. Everything is in the first few chapters of OW. Dive within your abilities, with a competent buddy and stay fit for physical activity.
