Way of the Lawless by Max Brand

Far away in the western sky Andy Lanning saw a black dot that moved in wide circles and came up across the heavens slowly, and he knew it was a buzzard that scented carrion and was coming up the wind toward that scent. He had seen them many a time before on their gruesome trails, and the picture which he carried was not a pleasant one.

But now the picture that drifted through his mind was still more horrible. It was a human body lying face downward in the sand with the wind ruffling in the hair and the hat rolled a few paces off and the gun close to the outstretched hand. He knew from Uncle Jasper that no matter how far the trail led, or how many years it was ridden, the end of the outlaw was always the same -- death and the body left to the buzzards. Or else, in some barroom, a footfall from behind and a bullet through the back.
