The story told in the video is based upon Stuart Lake's book, "Wyatt Earp". Lake's "quotes" of Earp's recollections seem unlikely. Here is a portion regarding this incident:
"I can see Curly Bill's left eye squinted shut, and his right eye sighting over that shotgun at me to this day, and I remember thinking, as I felt my coat jerk with his fire, 'He missed me; I can't miss him, but I'll give him both barrels to make sure.' I saw the Wells-Fargo plate on the gun Curly Bill was using and I saw the ivory butts of Jim Hume's pet six-guns in Hume's fancy holsters at Curly Bill's waist as clearly as could be. I recognized Pony Deal, and, as seven others broke for the cottonwoods, I named each one as he ran, saying to myself, 'I've got a warrant for him.' [Here he names the seven.] I knew Curly Bill was cut in two and I threw the loop of my shotgun over my saddle horn and grabbed for my rifle."
It doesn't sound like Wyatt claimed to have examined Curly Bill's body. I doubt that he really felt that the double-shot had literally cut him in two, but it's possible that he did believe it. It may have been another of Lake's melodramatic quotes, Earp being melodramatic or simply poor memory. Either way, it is not likely that Curly Bill was "cut in two". Shotgun wounds can be horrific and certainly fatal without literally cutting someone in two.
I'm more interested in the location that the video places this incident. The location is a very contentious issue. Does anyone know more about the archeology and the artifacts mentioned in the video? I'd be very interested in learning more...
