Dеfendant conditionally pled guilty to manufacturing marijuana, MCL 333.7401(2)(c); MSA 14.15(7401)(2)(c), and was fined $1,000. Defendant appeals as of right, and we affirm.
Defendant’s guilty plea was conditioned upon this Court’s review of the trial court’s decision on a motion to suppress evidence obtained pursuant to a search warrant. Defendant argued below and now argues on appeal that the affidavit offered in support of the warrant to search defendant’s residence was based on stale, false, and incomplete information; did not support a finding of probable *220 cause to search; and failed to establish the personal knowledge of an unnamed informant.
This Court’s analysis on appeal will be guided by the principles recently enunciated in
People v Russo,
The affidavit of Detective Sergeant Curtis Schram included the following pertinent facts to support probable cause:
(2) On 6/28/90 Hemp Tip number C-01-90 was received stating that a Karl Stumpf had received eight (8) shipments of marijuana seeds and/or equipment used for growing mаrijuana within the past 16 months at 18990 Victor ....
(3) A check with the utility company of 18990 Victor, shows that a Vivian Stumpf is living at that address. Further, that from 6/9/89 to 7/12/ 89, 1310 kwh hours of electricity was used. The following month the rate increased to 1537 kwh hours, and the following month increased to 1600 kwh hours.
(4) Affiant cоntacted the residence at 18990 Victor by telephone and a Karl Stumpf identified himself as being at the residence._
*221 (5) Affiant, on 9/11/90, observed a 1962 Chevrolet, 2 door, 90/MI, 776-YHN, parked in the driveway. lein showed the vehicle was registered to Karl Stumpf.
(6) A check of Karl Stumрf s arrest record shows that he has been arrested for drugs in the past.
(7) A check at 18990 Victor . . . was made by Affiant. It was observed that an upstairs window was covered up and had a fan. Further, the basement windows were also covered.
(8) On 8/8/90, Affiant obtained a seаrch warrant using the same information from the informant, and it resulted in a seizure of marijuana and items associated with the growing of marijuana.
(9) On 8/21/90, Affiant obtained a search warrant using the same information from the informant, and it resulted in a seizure of marijuana and items associated with the growing of marijuana.
(10) On 8/27/90, Affiant obtained a search warrant using the same information from the informant, and it resulted in a seizure of marijuana and items associated with the growing of marijuana.
(11) It is the belief of the Affiant, based upon ten years police experience and training, that Karl Stumpf is growing marijuana at 18990 Victor
The trial court conducted an evidentiary hearing on the motion to suppress on March 25, 1991. The only witness at that hearing was Sergeant Schram.
Schram explained that the tiр about the marijuana seeds and equipment was received from the Oregon State Police. They had received the information through the federal Drug Enforcement Administration. An individual arrested in Oregon by the dea was cooperating with the dea .and providing information on the shipment of marijuana seeds and equipment used to grow marijuana. Schram did not personally speak with the *222 informant, nor did he know who the informant was, but he received the information through the Michigan State Police.
Schram recounted that the police found marijuana in about eight out of nine searches conducted pursuant to the information provided by this informant. At the time this warrant was obtained, three out of four searches conducted were successful in finding marijuana or mаrijuana-growing equipment. The equipment and seeds came from a company operating a mail-order business, which shipped equipment and seeds to customers.
The warrant and affidavit were both prepared on September 13, 1990. On the same dаy, defendant’s residence was searched. As a result of that search, the police confiscated approximately fifteen small marijuana plants and eight larger ones.
The trial court denied defendant’s motion to suppress the evidenсe obtained pursuant to the warrant.
PERSONAL KNOWLEDGE OF THE INFORMANT
MCL 780.653; MSA 28.1259(3), as amended by
. The magistrate’s finding of reasonable or probable cause shall be based upon all the facts related within the affidavit made before him or her. The affidavit may be based upon information supplied to the complainant by a named or unnamed person if the affidavit contains 1 of the following:
(b) If the person is unnamed, affirmative allegations from which the magistrate may conclude that the person spoke with personal knowledge of the information and either that the unnamed *223 person is credible or that the information is reliable.
In general, the requirement that the informant have personal knowledge seeks to eliminate the use of rumors or reputations to form the basis for the circumstanсes requiring a search. See
People v Brooks,
We believe the specificity of the details provided by the informant in this case, regarding the shipments, dates, and defendant’s name and address, were substаntial indicia to support a finding that the informant spoke from personal knowledge. In addition, the affiant conducted an independent investigation that produced corroborating evidence and substantially verified the information supplied by the informant. See
People v Harris,
Aftеr reviewing the affidavit in a common-sense and realistic manner, we believe there was a sub *224 stantial basis for the magistrate to conclude the informant spoke with personal knowledge and was both credible and reliable.
FALSE INFORMATION
Defendant also arguеs that some of the information provided in the affidavit was false. In support, defendant relies on Schram’s admission at the evidentiary hearing that on the day defendant’s home was searched, another house was also searched, on the basis of аn almost identical affidavit, and that search failed to turn up any drugs or drug-producing equipment. Because the affidavit in this case did not contain any reference to the unsuccessful search, defendant argues that the affidavit contained false оr misleading information.
Franks v Delaware,
*225 After a review of the entire evidentiary hearing transcript, we do not аgree with defendant that the lack of specific reference to the unsuccessful search was a material omission. The mere fact that information provided by the informant did not produce evidence of the suspected criminal aсtivity in one isolated instance did not alone suggest that this informant was not reliable or credible. It is not unusual that illegal activity is terminated, temporarily discontinued, or moved during the interim period while police attempt to confirm information and seek а warrant. We also note that the three other searches from information supplied by this informant were successful.
Moreover, there was no evidence that Schram intentionally or recklessly omitted information. Indeed, because these two searches were conducted on the same day, it is plausible that the other search had not been concluded at the time Schram prepared the affidavit or that Schram had not been apprised of the results.
Defendant also argues thаt the statement that he received "marijuana seeds and/or equipment” was false. He contends that the police had no basis to believe he received marijuana seeds.
Schram believed that the majority of the information supplied by thе informant emanated from customer lists of a company that sold marijuana-producing equipment to customers by mail. However, that fact did not preclude a finding that the additional information provided by the informant regarding defendant’s receipt оf seeds was true and accurate. Defendant has not established that this was a false statement or a statement that the police recklessly used or knew was false. 2
We believe the trial court did not err in finding *226 there were no false material statements in the affidavit.
STALENESS OF THE INFORMANT’S INFORMATION
"Probable cause to search is concerned with whether certain identifiable objects 'are probably to be found at the present time in a certain identifiable place.’ ” 3 It cannot be assumed that evidence of a crime will remain indefinitely in a given place. Thus, staleness is a factor to weigh in determining if there is probable cause to search. Russo, supra, p 605.
The age of the information alone is not determinative, but must be evaluated as part of the particular circumstances of the case. Id., pp 605-606. The circumstances will vary depending upon such factоrs as "whether the crime is a single instance or an ongoing pattern of protracted violations, whether the inherent nature of a scheme suggests that it is probably continuing, and the nature of the property sought, that is, whether it is likely to be promptly dispоsed of or retained by the person committing the offense.” Id., pp 605-606.
We believe the facts of this case are sufficient to justify a finding of probable cause despite the lapse of time. The informant told law enforcement officials that eight shipments оf both marijuana seeds and equipment used for growing marijuana were sent to defendant at his residence during a period of sixteen months immediately preceding June 28, 1990. The circumstances of the suspected criminal enterprise included the growing of mаrijuana at defendant’s residence, not simply the possession of a specific quantity of drugs, but an ongoing criminal activity. Because plants require time to germi *227 nate and grow, the evidence was not likely to have dissipated despite the passage of time. Russo, supra, pp 605-606.
LACK OF PROBABLE CAUSE
Probable cause to search must exist at the time a warrant is issued. Id., p 606. Probable cause exists when a person of reasonable caution would be justified in concluding that evidence of criminal conduct could be found in a stated рlace to be searched. Id., pp 606-607.
Rather than engage in hypertechnical after-the-fact scrutiny of affidavits, we give great deference to the magistrate’s decision because of our preference for the use of search warrants. Id., pp 603-604. Reading the affidavit in a common-sense and realistic manner, we agree with the trial court that the magistrate properly issued the warrant in this case. The detailed information supplied by the informant, and the verification and corroboration by the police, provided the magistrate with a substantial basis to find that there was probable cause to search defendant’s residence for evidence of marijuana production.
Affirmed.
Notes
In addition, factual findings made by a trial court in relation tо a motion to suppress evidence are reviewed for clear error. This Court will not reverse those findings unless left with a definite and firm conviction that a mistake was made.
People v McKendrick,
Defendant has never requested production of the unnamed informant for purposes of testing the truthfulness of the statements.
