Yeah, the two different code sources were confusing. I bookmarked both since they're handy. Anyway, I went back and I think the difference is that one source was from a sar training manual (although from southern Arizona) and the other one was from the Maricopa county sheriff's office computer codes.
You'd think the codes would be universal, at least throughout the U.S. but apparently some agencies have their own inter-office codes. What I couldn't find was any manuals for all sar. If you run across one, let me know.
And yes, I hope little Jerold died quickly. Sadly though I've managed to educate myself a little too much and I don't think his end was peaceful. The thought of him out in the middle of nowhere, all alone is too much to bear. His poor mother - I can't imagine the pain.
