Searchers find missing Converse County deputy's body
I have been unable to find whether he was wearing a PFD. My guess is that due to the nature of the incident, he was not. One of the first things that we are taught in swiftwater rescue is that if you do not have your gear, don't go in the water, since it just creates more victims.
A brave move to be sure, and I have little doubt that his actions saved the girls life. But serves as a reminder as to why medals, and commendations for bravery are so often awarded posthumously.
