Walking around late at night in a dodgy area with a video camera you might expect to be lunged at by some shady character doing a deal they don’t want you to see. 50ft below the surface of the ocean filming coral reefs, however, is not somewhere you would expect someone to try and kill you.
This is exactly what happened to diver Rene Umberger. Check out the video, its pretty intense.
