I was once a certified lifeguard & first responder, and pulled a man from a river during a vacation. He had been underwater several minutes (the man couldn't swim), as he could not be seen--the water was murky & visibility was < 12 inches. He was not lifeless, as he vomited after rescue, but we was not resuscitated and died on the scene. It's been about 12 years now, I think. I made some mistakes which I think could have been avoided. Not the mistake of standing by, but I didn't keep my training at the front of my brain. Namely, I did not ensure 911 was called before we found the body, and I did not spend a few seconds trying to recruit more people to look for the body. Both of those may have saved his life, it's hard to say. I haven't found a silver lining, and I don't expect to. I simply hope that I can perform better in the event that such a thing happens again.
