DETECTIVE Danny Johnson was on patrol outside Tampa, Florida, when a report came through of a possible shooting in a junkyard three blocks away. Arriving on the scene, he found an elderly man sitting on a tractor, with a large hole in his leg that was bleeding profusely.
Realising it would be some time before the ambulance arrived, Johnson opened a packet of sand-like material and poured it into the wound. Within seconds the bleeding had practically stopped, and the man survived. "The medic told me that had I not put the substance in there, the guy would probably have bled out and died," he says.
