¶ 1. Jеffrey Loranger appeals from a judgment of conviction for manufacturing a controlled substance, maintaining a building for the use of manufacturing controlled substances, and possessing a firearm as a felon. He filed a motion to suppress evidence seized at his home under a search warrant, which the circuit court denied. There are two primary issues. The first is whether suppression of evidence is the proper remedy when police performed a thermal image scan on Loranger's home without a warrant, relying in good faith upon our decision in
State v. McKee,
*202
¶ 2.
Kyllo v. United States,
Background
¶ 3. On May 6, 1999, Iowa County Deputy Sheriff Steve Bennett requested that the Iowa County court commissioner issue a warrant authorizing the search of Jeffrey Loranger's home. In his affidavit in support of the search warrant, Bennett stated that Special Agent Scott Jess had interviewed a confidential informant on April 19, 1999. The informant told Jess that approximately eighteen months ago, he had been in Loranger's house, and Loranger had shown the informant his "marijuana grow operation." The informant observed "two to three grеen children's turtle pools filled with approximately 60-80 marijuana plants each." In addition, the informant observed "six to seven shop lights *203 with cloned marijuana plants underneath them," one 1500 watt light bulb, and one 2000 watt light bulb.
¶ 4. The affidavit also stated that, based on this tip, Special Agent Jess and Special Agent Gregory Phillips conducted a "thermal imagery site assessment" outside Lorangеr's home on May 5, 1999. The thermal imagery device indicated that "an unusual amount of heat was emanating from the wall of the northeast and north corner of the residence" in the basement area, but not from the roof. Further, according to Phillips, this suggested that the "unusual and uneven heat" was generated by "indoor grow lights, which are utilized for the indoor cultivation of marijuana."
¶ 5. Finаlly, the warrant contained information regarding the electric power used at Loranger's residence as compared to "the average monthly kilowatt usage." For the period of May 1, 1998, to March 31, 1999, the affidavit alleged that, according to information provided by the Alliant Energy Company, the average monthly kilowatt hour usage at Loranger's home was 1464 kilоwatt hours per month. Further, the affidavit alleged that the average monthly kilowatt usage for a residential home was between approximately 550 and 700 kilowatt hours per month.
¶ 6. The court commissioner issued the warrant, and police searched Loranger's home, after which the State charged Loranger with one count of manufacturing a controlled substance under Wis. Stat. §§ 961.41(1), 961.41(l)(h)l, and 961.14(4)(t), one count of maintaining a building for the use of manufacturing controlled substances under Wis. Stat. § 961.42(1), and five counts of possessing a firearm as a felon under Wis. Stat. § 941.29(l)(b). In response, Loranger moved to suppress all evidence obtained by the State as a result of the thermal search and the subsequent search of his
*204
home. Loranger claimed that the warrаntless thermal search was illegal and therefore could not provide probable cause to execute a warrant to search his home. In addition, Loranger filed a motion under
Franks v. Delaware,
¶ 7. The circuit court held evidentiary hearings on November 23, 1999, and February 1, 2000, after which it denied both of Loranger's motions. The court concluded that "the current position of Wisconsin authority holds that the use of a thermal imaging device ... is not a search within the meaning of the Fourth Amendment," and that Loranger had not proven by а preponderance of the evidence that Bennett made intentional falsehoods or showed a reckless disregard for the truth in his affidavit. Finally, the court concluded that the affidavit contained sufficient facts to support a finding of probable cause.
¶ 8. Loranger pleaded no contest to one count each of manufacturing a contrоlled substance, maintaining a building for the use of manufacturing controlled substances, and possessing a firearm as a felon. The circuit court sentenced Loranger to a total of five years in prison, but stayed the sentence pending appeal.
Opinion
A. Thermal Search
¶ 9. Loranger first argues that the officers' use of a thermal imaging device to detect heat emanating from his homе was a "search" within the meaning of the
*205
Fourth Amendment and article I, § 11, and was therefore unlawful because it was conducted without a warrant. Loranger further asserts that the evidence obtained through the thermal search should have been suppressed. The question whether police conduct violated the Fourth Amendment or article I, § 11, is a question of constitutionаl fact.
See State v. Marquardt,
2001WI App 219, ¶ 9,
¶ 10. We agree with Loranger that the use of a thermal imaging device to detect heat emanating from his home was a search under the Fourth Amendment and was therefore presumptively unreasonable. We disagree, however, that the evidence obtained through the search must be suppressed as a result.
¶ 11. In
State v. McKee,
¶ 12.
McKee,
however, was implicitly overruled by
Kyllo v. United States,
¶ 13. In accordance with
Kyllo,
we conclude that the State violated the Fourth Amendment when it used a thermal imaging device to detect heat coming from Loranger's home.
See State v. Pitsch,
¶ 14. Applying the holding of
Ward
here, we must likewise conclude that the evidence obtained through the thermal imaging device is admissible. In May 1999 when police used the device to detect heat emanating from Loranger's home,
Kyllo
had not yet been decided,' and
McKee
was applicable. Therefore, the police relied on
McKee
in good faith and suppressing the evidence would serve no remedial purpose.
But see United States v. Acker,
¶ 15. Loranger contends that Ward is distinguishable because it involved "the issue of how a search should be conducted rather than whether the search itself is permissible." Although this observation is correct, there is no language in Ward to suggest its holding was limited to improperly issued no-knock search warrants. Rather, the court broadly stated that "we believe that law enforcement officers and magistrates must be allowed to reasonably rely upon the pronouncements of this court." Id. at ¶ 62. Although "this court" could be interpreted as meaning only the decisions of the suрreme court and not the court of appeals, we see no logical reason to distinguish between published opinions of the court of appeals and the supreme court in *208 this context. Even the dissent in Ward recognized that the "majority opinion applies to any published opinion of the court of appeals or this court authorizing a search when the decision is latеr declared unconstitutional." Id. at ¶ 88 (Abrahamson, C.J., dissenting).
¶ 16. Loranger's reliance on the limitations of the holding in
State v. Eason,
B. Franks Motion And Probable Cause
¶ 17. The affidavit in support of the search warrant alleged that because strong lights are needed to grow marijuana indoors and these lights must operate continuously, those involved in the "indoor cultivation of marijuana" will use greater amounts of electricity than аverage. The affidavit also stated that Special *209 Agent Jess had reviewed records of Loranger's power usage, provided by Alliant Energy Company, from April 30, 1996, to March 31, 1999. According to the affidavit, Loranger's average monthly kilowatt hour usage was 914 kilowatt hours per month from April 30, 1996, to April 2, 1997, 1102 kilowatt per month from May 1, 1997 to April 1, 1998, and 1464 kilowatt hours per month from May 1, 1998, to March 31, 1999.
¶ 18. Thе affidavit also contained the following two paragraphs:
Agent Jess has stated that he has reviewed documents provided by CEASE (Cannabis Enforcement and Suppression Effort) State Coordinator Stan Blazek. CEASE is a law enforcement program administered by the Wisconsin Department of Narcotics Enforcement that functions to eradicate cannabis.
The first CEASE document, dated October, 1997, indicated that the average monthly kilowatt usage for a residential house in the Madison, WI regional area was 600 kilowatt hours per month. The second CEASE document, dated July 29, 1997, indicated the average monthly kilowatt usage for a single family residence was 708 kilowatt hours per month. The information contained in this document was provided to CEASE by Madison Gаs & Electric Company. The third CEASE document, received by CEASE on August 22, 1997, indicated that the residential customers living within a village or city use approximately 560 to 600 kilowatt hours per month and residential customers living in a township have a slightly higher average of 650 kilowatt hours per month. The document indicated that individual conditions such as heat source and lifestyle will cause deviations from the above numbers. The information contained in the document was provided to CEASE by Wisconsin Power & Light.
*210
¶ 19. Loranger asserts that the above paragraph contains "wrongful omissions," contrary to
Franks v. Delaware,
¶ 20. In his brief in chief, Loranger points out that the documents the affidavit refers to do not: (1) disclose the month, season, or year on which the electric usage figures are based; (2) indicate that Arena, Wisconsin, which is the location of Loranger's home, is included in the figures; or (3) "provide any specifications for the size, type of construction, heating and cooling system, appliances and other furnishings, number of occupants, or other data for an average 'residential customer.'" In addition, he notes that the documents indicate that air conditioning or electric heating can increase energy consumption.
¶ 21. Although we agree with these observations, we disagree that they demonstrate the affidavit wаs made with reckless disregard for the truth. Rather, the affidavit accurately reflects the information that is contained in the documents. The affidavit does not allege that the statistics regarding average usage were specific to a particular season or year, or that they included Arena, Wisconsin. And the affidavit expressly points out that "individual conditions such as heat *211 source and lifestyle will cause deviations from the above numbers." The issue, therefore, is not whether the affidavit included false statements, but whether the electrical usage information contained in the affidavit, as limited as it was, supported a finding of probable cause.
¶ 22. In our review of a warrant-issuing court commissioner's finding of probable cause, we accord "great deference," to the commissioner's determination.
State v. Multaler,
¶ 23. Viewing the totality of the circumstances, we conclude that the issuing court commissioner had a substantial basis for concluding that probable cause existed. We agree with Loranger that the comparative statistics regarding Loranger's versus the "average" use of electricity could have been more specific. Not knowing exactly when or where the "average" figures were
*212
extracted diminishes their value. Loranger does not challenge the veracity, however, of the information that was provided. The affidavit alleged that the average monthly kilowatt hour usage for Loranger's residence was 1464 kilowatt hours per month. This was more than double each of the comparative averages provided in the affidavit. It would not be unreasonable to infer that a disparity of 100% is unlikely to be explained based upon the year or what part of the state the statistics came from. Although these statistics would not be sufficient to support a finding of probable cause on their own,
see United States v. Field,
¶ 24. In addition, the affidavit relied upon a tip from a confidential informant. Loranger contends that the warrant-issuing commissioner could not rely upon this tip because it was based on information almost eighteen months old. Although search warrants may not rest on stale evidence,
Sgro v. United States,
By the Court. — Judgment affirmed.
