(1) DESCRIPTION AND ISSUANCE. A search warrant is an order signed by a judge directing a law enforcement officer to conduct a search of a designated person, a designated object or a designated place for the purpose of seizing designated property or kinds of property. A judge shall issue a search warrant if probable cause is shown.(2) WARRANT UPON AFFIDAVIT. A search warrant may be based upon sworn complaint or affidavit, or testimony recorded by a phonographic reporter or under sub. (3) (d), showing probable cause therefor. The complaint, affidavit or testimony may be upon information and belief. The person requesting the warrant may swear to the complaint or affidavit before a notarial officer authorized under ch. 140 to take acknowledgments or before a judge, or a judge may place a person under oath via telephone, radio, or other means of electronic communication, without the requirement of face-to-face contact, to swear to the complaint or affidavit. The judge shall indicate on the search warrant that the person so swore to the complaint or affidavit.(3) WARRANT UPON ORAL TESTIMONY.
(a)General rule. A search warrant may be based upon sworn oral testimony communicated to the judge by telephone, radio or other means of electronic communication, under the procedure prescribed in this subsection.(b)Application and issuance.1. `Duplicate originals.’ The person who is requesting the warrant may prepare a duplicate original warrant and read the duplicate original warrant, verbatim, to the judge. The judge shall enter, verbatim, what is read on the original warrant. The judge may direct that the warrant be modified. If the judge determines that there is probable cause for the warrant, the judge shall order the issuance of a warrant by directing the person requesting the warrant to sign the judge’s name on the duplicate original warrant. In addition, the person shall sign his or her own name on the duplicate original warrant. The judge shall immediately sign the original warrant and enter on the face of the original warrant the exact time when the warrant was ordered to be issued.2. `Electronic transmission.’ The person who is requesting the warrant may sign his or her own name on the warrant and transmit it to the judge. The judge may modify the warrant. If the judge determines that there is probable cause for the warrant, the judge shall order the issuance of a warrant by signing the warrant and entering on the face of the warrant the exact time when the warrant was ordered to be issued. The judge shall immediately transmit the signed warrant to the person who requested it.(c)Probable cause. The finding of probable cause for a warrant upon oral testimony shall be based on the same kind of evidence as is sufficient for a warrant upon affidavit.(d)Recording and certification of testimony. When a caller informs the judge that the purpose of the call is to request a warrant, the judge shall place under oath each person whose testimony forms a basis of the application and each person applying for the warrant. The judge or requesting person shall arrange for all sworn testimony to be recorded either by a court reporter or by means of a voice recording device. The judge shall have the record transcribed. The transcript, certified as accurate by the judge or reporter, as appropriate, shall be filed with the court. If the testimony was recorded by means of a voice recording device, the judge shall also file the original recording with the court.(e)Contents. The contents of a warrant upon oral testimony shall be the same as the contents of a warrant upon affidavit.(f)Entry of time of execution. The person who executes the warrant shall enter the exact time of execution on the face of the duplicate original warrant.(4) LOCATION OF SEARCH. A search warrant may authorize a search to be conducted anywhere in the state and may be executed pursuant to its terms anywhere in the state.(5) SIGNATURES.
