delivered the Opinion of the Court.
¶1 Defendant Len Ray Zito appeals the order of the Twenty-First Judicial District Court, Ravalli County, denying his motion to suppress evidence seized under a search warrant, suppress statements made to law enforcement upon his arrest, and dismiss this case. We affirm.
¶2 On November 17, 2004, pursuant to a plea agreement, Zito pled guilty to several drug related felonies and a misdemeanor, reserving his right to appeal the denial of his motions to suppress and dismiss.
¶3 Zito moved to suppress all evidence obtained by virtue of a search of his property on October 23, 2003, pursuant to a search warrant issued the previous day. He also moved to suppress statements he made to law enforcement at the time of his arrest. The motion was heard, and on April 9, 2004, the District Court entered its findings of fact and conclusions of law and order denying Zito’s motions.
¶4 Ravalli County Sheriffs Detective Jase Basnaw applied for and was granted a search warrant for Zito’s property on October 22, 2003, the same day a confidential informant had reported seeing marijuana plants at Zito’s residence. The warrant was issued by the Ravalli County Justice Court. On October 23, 2003, several members of the Ravalli County Sheriffs Office, including Detective Basnaw, and officers from the Montana State Division of Criminal Investigation executed the search warrant. The search resulted in the confiscation of approximately fifty marijuana plants located in an abandoned basement, under a canopy, and in several other places unobservable from the air. The marijuana plants were in the process of being harvested and dried. The search also produced paraphernalia related *314to the production and use of marijuana, as well as a number of guns. Zito was found hiding in a gully approximately two hours after the search commenced.
¶5 Upon consideration of the affidavit in support of the search warrant, the reviewing District Court found the facts supporting the warrant to be as follows:
(1) On September 18, 2003, a concerned citizen informed Detective Basnaw that Mr. Zito was growing marijuana at his place. This tip was not based on personal observation.
(2) On September 29,2003, Cl [Confidential Informant] met •with Detective Basnaw and informed him that Mr. Zito currently had a grow operation at his place, under a yellow tarp in front of his residence and in a pump house. Cl said that plants were budding and ready for harvest. Cl, by virtue of the absence of a sworn statement attesting to Cl’s veracity, is not deemed a reliable informant. Cl’s tip was not based on Cl’s personal observation.
(3) On October 1, 2003, Detective Basnaw flew over the property and took photographs of planter boxes, several pots, and a yellow tarp in front of Mr. Zito’s residence. The cultivation indicia were obscured from view on the ground by natural barriers and junk vehicles.
(4) On October 1,2003, following the flight, Detective Basnaw met with Cl and showed Cl the photographs. Cl confirmed the area in the photos where the marijuana was grown, identified the planter boxes as the site where marijuana was grown during the summer of2002, gave the reason for the use of the tarp as provided by Mr. Zito’s sons, and identified an unfinished, covered basement in the photos as the location for hanging the plants to dry. Except for identifying the planter boxes, Cl’s information was not based on personal observation.
(5) On October 4, 2003, Cl informed Detective Basnaw that Cl had been to Mr. Zito’s residence, and although Cl was not in a position to see the marijuana plants, Cl smelled them.
(6) On October 22, 2003, Cl informed Detective Basnaw that Cl had been to Mr. Zito’s residence and had seen approximately 30[,] four to five foot long marijuana plants hanging on the south wall of the unfinished basement.
(7) Mr. Zito has a prior drug-related criminal conviction.
(8) Viewing all these facts through the lens of his significant training and experience, Detective Basnaw concludes that Mr.
*315Zito is growing marijuana.!1]
¶6 We review a district court’s denial of a motion to suppress to determine whether the court’s findings of fact are clearly erroneous and whether its interpretation and application of the law are correct. State v. Meyer, 2004 MT 272, ¶ 11, 323 Mont. 173, ¶ 11, 99 P.3d 185, ¶ 11; State v. Martinez, 2003 MT 65, ¶ 19, 314 Mont. 434, ¶ 19, 67 P.3d 207, ¶ 19. Zito does not challenge the factual findings relevant to the search warrant, thus we address whether the District Court properly applied the law in concluding that the affidavit in support of the warrant was sufficient to establish probable cause.
¶7 We have adopted the “totality of the circumstances” test set forth in Illinois v. Gates (1983), 462 U.S. 213, 103 S.Ct. 2317, 76 L.Ed.2d 527, to evaluate whether probable cause supported the issuance of a warrant. State v. Barnaby, 2006 MT 203, ¶ 29, 333 Mont. 220, ¶ 29, 142 P.3d 809, ¶ 29; State v. Reesman, 2000 MT 243, ¶ 24, 301 Mont. 408, ¶ 24, 10 P.3d 83, ¶ 24. Under the totality of the circumstances test, the issuing judicial officer must make a practical, common sense determination, given all the evidence contained in the application for a search warrant, whether a fair probability exists that contraband or evidence of a crime will be found in a particular place. Barnaby, ¶ 29; Reesman, ¶ 24; Gates, 462 U.S. at 238, 103 S.Ct. at 2332, 76 L.Ed.2d at 548.
¶8 Our function as a reviewing court is to ensure ultimately that the issuing judicial officer had a “substantial basis” to determine probable cause existed before issuing the search warrant. Barnaby, ¶ 30. However, it is critical in our review that a judicial officer’s determination that probable cause exists be paid great deference and every reasonable inference possible be drawn to support that determination. Reesman, ¶ 19; Gates, 462 U.S. at 236, 103 S.Ct at 2331, 76 L.Ed.2d at 547 (“magistrate’s determination of probable cause should be paid great deference by reviewing courts.”) (internal quotation omitted).
¶9 An application for a search warrant must state facts sufficient to show probable cause to issue a warrant. Barnaby, ¶ 30. A determination of probable cause does not require facts sufficient to make a showing of criminal activity; rather, the issuing judicial officer must only determine that there exists a probability of criminal activity. Barnaby, ¶ 30; State v. Rinehart (1993), 262 Mont. 204, 210, 864 P.2d *3161219, 1222. Probable cause must be determined solely from the information contained within the search warrant application. Barnaby, ¶ 30; Rinehart, 262 Mont. at 211, 864 P.2d at 1223.
¶10 The affidavit in support of the warrant in this case stated the informant had told Detective Basnaw that he had been to Zito’s property about eighteen days prior, and he had smelled marijuana plants there. Further, this same informant told Detective Basnaw that he had been on the subject property the same day the affidavit was presented, and had seen over thirty marijuana plants. The informant was not anonymous, and the information he provided was not hearsay. Thus, if the informant could be shown to be reliable, there was probable cause to issue the search warrant. Reesman, ¶ 31.
¶11 Detective Basnaw’s affidavit in support of the warrant stated that the informant had a documented history with marijuana, and that Detective Basnaw knew from experience that the informant would recognize marijuana. The affidavit also detailed the relevant information provided by the informant as noted above in ¶¶ 5 and 10. However, the affidavit did not expressly state that the informant had provided reliable information in the past, was making a statement against his interest, or was acting as a concerned citizen. See Reesman, ¶¶ 32-35. Where such a statement is lacking, a confidential informant’s information regarding criminal activity requires further corroboration in order to supply a judicial officer with a sufficient substantial basis for a probable cause determination. State v. St. Marks, 2002 MT 285, ¶ 25, 312 Mont. 468, ¶ 25, 59 P.3d 1113, ¶ 25.
¶12 The corroboration must reveal indicia of human conduct that becomes suspicious when viewed in conjunction with the incriminating information received from the informant. State v. Griggs, 2001 MT 211, ¶ 50, 306 Mont. 366, ¶ 50, 34 P.3d 101, ¶ 50. In order to reveal this indicia of suspicious conduct, officers may investigate and corroborate otherwise innocent and non-criminal activity with further observations and evidence of otherwise innocent and non-criminal activity. Griggs, ¶ 50. Here, the police flew over Zito’s property and confirmed the informant’s description of the suspect areas, including the yellow tarp and junk cars that obscured areas of the premises where the marijuana was said to be grown. The informant’s statements describing planter boxes and pots, and their placement and location, were also confirmed.
¶13 The flyover corroborated the reliability of the informant’s information in two ways. First, it showed that he knew, in detail, the layout of Zito’s property, which confirmed that he had been there as he *317had told Detective Basnaw. Second, it provided confirmation of information that, although innocent by itself, was consistent with a marijuana grow operation, when considered in conjunction with the prior tip that such activity was taking place there and the subsequent tip that there were over thirty marijuana plants located on Zito’s property.
¶14 The fact that the confidential informant’s tip that he had seen marijuana on Zito’s property came after the flyover does not negate the corroborative value of this information. Information that over thirty marijuana plants were seen drying in the basement was entirely consistent with the earlier report made before the flyover that the plants were “budding and ready for harvest.” Further, the fact that information in the earlier report was not based on personal observation, does not preclude a finding of reliability through independent corroboration. See State v. Gray, 2001 MT 250, ¶¶ 4, 21, 307 Mont. 124, ¶¶ 4, 21, 38 P.3d 775, ¶¶ 4, 21 (innocent facts were sufficient to corroborate information from a confidential informant who had not personally observed any criminal activity).
¶15 Further, Detective Basnaw stated in his affidavit that he knew from training and experience that the strategic placement of the junk vehicles and tarps was indicative of secluding an area for illegal activity. A district court may consider the judgment and experience of a law enforcement officer in its determination of the significance of innocent facts and their consistency with the reported criminal activity. Gray, ¶ 32 (citing Gates, 462 U.S. at 231-232); see also St. Marks, ¶ 36 (“We conclude we should lend credence to [investigating officer’s] judgment. His experience and training provided a reasonable basis for his conclusions concerning [defendant’s] behavior.”).
¶16 Another routine piece of information indicating police corroboration is criminal background checks. Reesman, ¶ 45. Law enforcement investigated and found that Zito had a prior drug-related criminal conviction. This court has held that one’s criminal history is “one of the many factors to be considered under the totality of the circumstances test.” State v. Johnson (1995), 271 Mont. 385, 390, 897 P.2d 1073, 1076-1077 (quoting State v. Hook (1992), 255 Mont. 2, 6, 839 P.2d 1274, 1277); State v. Morse, 2006 MT 54, ¶ 18, 331 Mont. 300, ¶ 18, 132 P.3d 528, ¶ 18; State v. Anderson, 1999 MT 60, ¶¶ 12-14, 293 Mont. 490, ¶¶ 12-14, 977 P.2d 983, ¶¶ 12-14; see also Gray, ¶¶ 20-21 (criminal history of accomplice, involving dangerous drugs, supported corroboration and probable cause).
¶17 Finally, at least one concerned citizen had informed Detective *318Basnaw that Zito was growing marijuana, albeit such information was not based on personal observation. While this tip from a concerned citizen would not be adequate to support probable cause without further investigation, it still had some probative value in determining probable cause, under the totality of the circumstances test. St. Marks, ¶ 41; see also State v. Holstine (1993), 260 Mont. 310, 315, 860 P.2d 110, 113 (“Factors which are of little probative value alone, however, when taken together under the Gates ‘totality of the circumstances’ test, provide the basis for a determination of substantial evidence to conclude probable cause existed to issue the search warrant.”).
¶18 The facts garnered from the flyover are indicia of human conduct that legitimately became suspicious to the issuing judicial officer when considered along with the personal observations of the informant, the drug-related criminal history of the property’s occupant, the tip from a concerned citizen, and the opinion of a detective with substantial experience and training in dangerous drug related activities. See Gray, ¶ 21 (innocent facts that defendant’s home had four new air vents, which based on detective’s experience were required for a grow operation; his utility records evidenced a surge in power usage; his alleged accomplice had a criminal history; and his brother, a known drug user, frequented the residence, were sufficient to corroborate information from a confidential informant who had not personally observed any criminal activity); St. Marks, ¶¶ 34-37 (“independent corroboration of [defendant’s] motel room number, together with his method of payment [cash] and the fact that he had a local address, added to [his] suspicious character ... when taken as a whole with the ... three anonymous phone calls and [alleged partner’s] arrest and possession of ... cocaine.”); see also Morse, ¶ 17 (innocent fact of possessing an empty digital scale box, considered in the context of the search warrant, sufficiently corroborated information from anonymous informants that defendant was selling drugs); State v. Palmer, 2003 MT 129, ¶¶ 21-23, 316 Mont. 46, ¶¶ 21-23, 68 P.3d 809, ¶¶ 21-23 (video surveillance revealed no actual criminal activity, but when coupled with training and experience of narcotics officer, sufficiently corroborated incriminating information received from informant); Hauge v. District Court, 2001 MT 255, ¶ 25, 307 Mont. 195, ¶ 25, 36 P.3d 947, ¶ 25 (“Officer ... sufficiently corroborated the Cl’s information by verifying the identities of the occupants of the trailers and the ownership of the vehicles; ... by personally observing the mobile homes on three separate occasions and finding the traffic patterns to be just as the Cl described; and by contacting a neighbor *319who had previously complained of drug activity and heavy traffic in the area and confirming that the traffic patterns still continued.”).2
¶19 Considering the totality of the circumstances, we conclude that the District Court did not err in denying Zito’s motion to suppress the evidence secured by execution of the search warrant.
¶20 We next consider Zito’s argument that all statements he made to law enforcement must be suppressed pursuant to § 46-6-107, MCA, and Miranda v. Arizona (1966), 384 U.S. 436, 86 S.Ct. 1602, 16 L.Ed.2d 694, which require that before being questioned, a person in custody must be advised that his statements may be used against him and that he has the right to consult with an attorney.
¶21 Zito was not questioned by the first deputy who took him into custody or any other law enforcement officer when he was first apprehended. Then, moments after Zito had been taken into physical custody, Detective Basnaw identified himself to Zito and told him that the sheriffs office was executing a search warrant for a “marijuana grow operation.” Zito responded with the gratuitous statement that he had a “medical grow.” Detective Basnaw did not question Zito about this statement at that time, but only asked Zito if he had any weapons on his person. Zito responded that he had a back injury. He was then escorted to a police vehicle were he was read his Miranda rights and questioned by Detective Basnaw, who recorded the conversation. Zito contends that because his statement regarding the medical grow was made while he was in custody and prior to being Mirandized, the statement could not later be used to elicit further statements, after he had been given his rights.3
*320¶22 The Miranda warnings are not required to be given by law enforcement unless one is subject to a custodial interrogation. State v. Reavley, 2003 MT 298, ¶ 18, 318 Mont. 150, ¶ 18, 79 P.3d 270, ¶ 18; § 46-6-107, MCA. A custodial interrogation is defined as, “questioning initiated by law enforcement officers after a person has been taken into custody or otherwise deprived of his freedom of action in any significant way[.]” Reavley, ¶ 18 (quoting Miranda, 384 U.S. at 444, 86 S.Ct. at 1612, 16 L.Ed.2d at 706). There is no dispute that Zito was in custody at the time he made the statement to Detective Basnaw that he had a “medical grow.” However, the record is clear that Zito was not questioned by any law enforcement officer, or otherwise coerced or induced to make the statement in question. Since there was no interrogation, the statement does not fall under the auspices of Miranda. See State v. Thompson (1989), 237 Mont. 384, 387, 773 P.2d 722, 724; State v. DePue (1989), 237 Mont. 428, 430-432, 774 P.2d 386, 388-389. Because the initial statement was not elicited in violation of Zito’s constitutional rights, we need not consider the argument that it somehow tainted subsequent statements. Thus, the District Court did not err in denying Zito’s motion to suppress his statements.
¶23 Affirmed.
JUSTICE COTTER, LEAPHART, MORRIS and RICE concur.The remainder of the search warrant application was excised by the reviewing District Court.
The present cases is unlike Griggs, where the “innocent facts” corroborated by law enforcement were totally unrelated to the suspected criminal activity. In Griggs, the corroboration of the defendant’s address, the fact that he used to be in the military, he drove a Ford truck, and that his trailer home had new trim, failed “to supply the magistrate with any indicia of human conduct even remotely associated with the criminal activity alleged by the anonymous informant-that [defendant] was cultivating psilocybin mushrooms in his private residence for the purpose of distribution in some manner.” Griggs, ¶¶ 7, 51. As discussed above, the corroborated facts relating to Zito were clearly pertinent to the harvesting of marijuana, and confirmed as such by an experienced narcotics detective.
The relevant portion of the taped interview, in which Zito claims Basnaw elicited further information in violation of Miranda, immediately followed his Miranda warning, and reads as follows:
Detective Basnaw:... Um, basically y [sic], you’re aware of why we’re here?
Len Zito: Yep.
Detective Basnaw: And we kinda’ talked there.
Len Zito: Yeah.
Detective Basnaw: Uh, when I mentioned it to you you did say that you do have *320a medical grow uh, for your, yourself and you have some injuries? Len Zito: Yeah
