Minn. Stat. § 626.16: DELIVERY OF COPY OF WARRANT AND RECEIPT.

When the officer conducts the search the officer must give a copy of the warrant and, when property or things are taken, a receipt therefor (specifying it in detail) to the person in whose possession the premises or the property or things taken were found; or, in the absence of any person, the officer must leave such copy of the warrant and receipt in the place where the property or things were found. Such delivery of a copy of the warrant shall constitute service.
