S.D. Codified Laws § 34A-6-112
If the scrap metal business is notified by a law enforcement officer that an item of nonferrous metal property has been reported as stolen, a scrap metal business shall hold that property intact and safe from alteration, damage, or commingling, and shall place an identifying tag or other suitable identification on the property. The scrap metal business shall hold the property for a period of time as directed by the law enforcement agency up to a maximum of ten business days.
A law enforcement officer may not place on hold any item of nonferrous metal property unless that law enforcement agency reasonably suspects that the property is a lost or stolen item. Any hold that is placed on the nonferrous metal property shall be removed within ten business days. If the property on hold is determined not to be lost or stolen, the nonferrous metal property shall be returned to the owner or released.
