“Finding” Missing Stock

“[A] number of overlanders ruefully discovered that even when a horse trade had been accomplished they could not be absolutely certain that the horse was definitely theirs, since a fellow emigrant, from whom the horse had initially been stolen, occasionally came up to claim his property. . . . 

There was also a profitable variation on this deceitful tactic. Indians would steal horses or other stock, make an arrangement on a certain price for ‘finding’ the animas with the emigrants from whom they had stolen them, and then quickly appear with the animals to claim the reward. Overlanders suspected Indians of employing this strategem as early as 1843.”
