Execution of search warrant is timely if in compliance with sub. (1) and if probable cause which led to issuance still exists at time of execution. Defense has burden of proof in timeliness challenge. State v. Edwards, 98 Wis. 2d 367, 297 N.W.2d 12 (1980).

Law enforcement’s failure to return an order and inventory within the confines of this section and s. 968.17 did not render the execution of the order unreasonable. The timely return of a warrant is a ministerial duty that does not affect the validity of the search absent prejudice to the defendant. State v. Sveum, 2010 WI 92, 328 Wis. 2d 369, 787 N.W.2d 317, 08-0658.

A search warrant issued for the placement and use of a global positioning system (GPS) tracking device is not a warrant issued “for the purpose of seizing designated property or kinds of property” under ss. 968.12(1) and 968.13 and is therefore not subject to the requirements of this section or s. 968.17. State v. Pinder, 2018 WI 106, 384 Wis. 2d 416, 919 N.W.2d 568, 17-0208.
