Wyo. Stat. § 35-10-104
It shall be the duty of the owner, or person having charge of an animal which may die in this state, to remove the carcass to a distance of not less than half a mile from the nearest human habitation, or to bury it with not less than two (2) feet of soil over it; and every person failing to so remove or bury such carcass, for more than forty-eight (48) hours, shall upon conviction, be fined in a sum not exceeding one hundred dollars ($100.00). And should such animal be the property or in charge of some person passing through this state, then any peace officer may (without warrant) detain the owner or person in charge of such animal, or of the flock or herd from which it died, as soon as such owner or person shall have shown an intention not to so bury or remove said carcass, by removing from it, or removing such flock or herd from it a distance of half a mile or more, a reasonable time, not to exceed two (2) days, until a warrant can issue upon an information duly sworn to. And the brand upon such animal may be given in proof of the ownership of the same.
