This аppeal challenges the district court’s denial of Reggie Tietsort’s motion to suppress evidence that was found at his residence before and after the issuance of a search warrant. The principal inquiry is whether the warrant was invalid as the product of prior unlawful searches. We vacate the district court’s order denying Tietsort’s motion and remand for further fact-finding.
I.
FACTUAL & PROCEDURAL BACKGROUND
In November 2004, detectives Sarrazolla and Furniss of the Garden City Police Department were investigating the theft of a blue Pontiac. They had received a tip that the vehicle might be located at a rural residence in Boise County. The detectives went to this property and knocked on the door of the house. Although the detectives heard someone inside, no one answered the knock. The detectives then walked around the property, including the back of the house and around a nearby barn. The bam was at least partially enclosed on three sides but open in the front. While the detectives did not find the stolen vehicle they were searching for, they saw a red Ford Focus and a white Cargo Plus utility trailer parked in the barn. The detectives later testified that they could see the trailer’s serial number from the driveway, but they admitted that they also walked into the barn to obtain the license plate and vehicle identification numbers for the Focus. A computer check disclosed to the detectives that the Focus and the utility trailer had been reported stolen.
Detectives Sarrazolla and Furniss left the property to request assistance from the Boise County sheriffs office, and returned about fifteen minutes later with two Boise County deputies. The deputies (and perhaps Furniss) remained on or near the entrance to the driveway while Sarrazolla left to apply for a search warrant. Seeing that the police had returned, Tietsort emerged from his house ten or fifteen minutes later and conversed with the deputies. The deputies explained that there were vehicles on the property that were believed to be stolen and that they were waiting for a search warrant. They asked Tietsort for permission to search the premises, and he responded that he would give consent. One of the deputies was then sent to fetch Detеctive Sarrazolla, who halted his attempt to secure a warrant. Sarrazolla returned to the property shortly thereafter, and he informed Tietsort that the detectives had discovered the stolen Ford and utility trailer on the property. Tietsort said that a friend had left those items a month before. At Sarrazolla’s request, approximately one hour after the detectives’ initial arrival, Tietsort signed a written consent to search all bams and vehicles on the property. He declined, however, to permit a search of his house. The consеnt search of outbuildings yielded evidence of additional stolen items, including several snowmobiles and another trailer.
Based on this evidence, the officers obtained a warrant to search the interior of the vehicles and the house for personal property that reportedly had been stolen with the vehicles. While executing the warrant, they discovered methamphetamine, marijuana, paraphernalia, and additional stolen property, including firearms. The manufacturer identification number on some of the stolen property had been defaced. Tietsort was charged with possession of methamphetamine with the intent to deliver, Idaho Code § 37-2732(a)(l)(A); possession of marijuana with the intent to deliver, I.C. § 37-2732(a)(1)(B); two counts of grand theft of a firearm, I.C. § 18-2407(l)(b)(6); seven counts of defacing, altering, or obliterating a manufacturer’s identification number, I.C. § 18-2410; five counts of misdemeanor possession of a legend drug, I.C. § 54-1732(c); and misdemeanor possession of drug paraphernalia, I.C. § 37-2734A. He was not charged with theft of the vehicles in his barn.
Tietsort filed a motion to suppress all evidence found on his property on the day of his arrest, invoking both federal and Idaho constitutional protections. The district court denied the motion, and 1 Tietsort then eondi *115 tionally pleaded guilty to one count each of possession of methamphetamine with the intent to deliver; grand theft of a firearm; and defacing, altering, or obliterating a manufacturer’s identification number, reserving the right to appeal the denial of his suppression motion. In this appeal, he argues that the detectives’ initial search in and around his bam was unconstitutional and tainted both his subsequent consent and the warrant. He also asserts that his cоnsent was tainted because he was unlawfully detained by the officers before the consent was given.

ANALYSIS
On review of a decision to grant or deny a motion to suppress evidence, we defer to the trial court’s findings of fact unless they are clearly erroneous.
State v. Hawkins,
The Fourth Amendment to the United States Constitution and Article I, Section 17 of the Idaho Constitution each guarantee “[t]he right of the people to be secure in their persons, houses, papers and effects against unreasonable searches and seizures.” These provisions protect a person’s expectation of privacy which society is prepared to recognize as reasonable.
Oliver v. United States,
Interpreting the Idaho Constitution, our courts define “curtilage” more broadly than does the United States Supreme Court for Fourth Amendment purposes, to include outbuildings and drives within the areas protected from unreasonable searches.
Webb,
Even under Idaho constitutional jurisprudence, however, not all entries by law enforcement officers onto the curtilage of a home infringe upon constitutionally protected expectations of privacy. Under the open view doctrine, when the police come onto private property to conduct an investigation or for some other legitimate purpose and restrict their movements to places where ordinary visitors could be expected to go, observations from such vantage points are lawful.
Id.; State v. Clark,
What is lawfully seen in open view may furnish probablе cause for a warrant.
Doe v. State,
There were three searches in this case: (1) the initial search when the police walked around the curtilage of the home and went into the barn; (2) the search of outbuildings and vehicles conducted with Tietsort’s consent; and (3) the search of the interior of the house and vehicles pursuant to the warrant. Tietsort contends that all three of these searches were unlawful. He maintains that the first was illegal because police entered the barn and other areas of the curtilage to which visitors are not impliedly invited, that the second search was unlawful because Tietsort’s consent was involuntary and was tainted by the initial unlawful search, and that the third search was unlawful because the warrant was likewise tainted by the prior illegalities. The State acknowledges that the entry into the barn on the first search violated Tietsort’s constitutionally protеcted privacy interest, and because the license and vehicle identification number of the Ford Focus could be seen only from inside the barn, that information was acquired illegally. As there was no testimony that the officers could read the vehicle identification number or license number on the trailer from a position outside the barn, that evidence also must be deemed fruit of the unlawful entry into the barn. The State maintains, however, that the detectives lawfully observed the manufacturer’s serial number on the utility trailer from a position outside the barn, thereby gaining information that identified the trailer as stolen and provided probable cause for a search warrant. The State also contends that Tietsort’s consent to the second search was lawfully obtained and therefore evidence found in that search also supported the warrant for the third search.
We conclude that the disposition of these opposing contentions turns upon a single issue-whether the officers lawfully observed in open view the serial number on the utility trailer. 2 This question as to whether *117 the officers read the trailer’s serial number from a lawful vantage рoint affects the validity of Tietsort’s subsequent consent to another search and, consequently, also affects the validity of the warrant that was issued on the basis of evidence found in the first two searches. Unfortunately, the district court did not make factual findings on this point. We are therefore compelled to remand this case for the district court to make findings based upon the conflicting evidence in the record. Before we do so, we shall explain why the case converges upon this question.
It is readily apparent that if the consent given by Tietsort for the second search was valid, the warrant was valid, for evidence found in the second search amply provided probable cause for the search warrant. If all evidence found in the first search was unlawfully acquired however, and Tietsort’s consent was tainted by that preceding illegality, then there was no evidence that was not gleaned by violation of Tietsort’s constitutional rights to support the warrant application. That is, if the serial number was unlawfully acquired, then the consent may fall because it was derived through exploitation of that illegality, and if the consent falls then the evidence from the second search could not properly be used to support the warrant. The State having identified no other lawfully acquired evidence supporting the warrant application, the warrant would be invalid also, and all evidence derived from the three searches would have to be suppressed.
When police conduct has violated an accused’s constitutional rights before he consents to a search, the State must prove that the consent was not procured by exploitation of the previous illegality.
Wong Sun v. United States,
We need not hold that all evidence is “fruit of the poisonous tree” simply because it would not have come to light but for the illegal actions of the police. Rather, the more apt question in suсh a case is “whether, granting establishment of the primary illegality, the evidence to which instant objection is made has been come at by exploitation of that illegality or instead by means sufficiently distinguishable to be purged of the primary taint.”

The analysis was carried forward in
Brown,
where officers broke into the defendant’s residence and arrested him without probable cause. They then interrogated him at the police station after first advising him of his
Miranda
rights.

During this interrogation, Brown admitted involvement in a murder. The question presented to the Supreme Court was whether the
Miranda
warnings administered at the police station
*118
broke the causal connection betwеen the illegal arrest and the statements so that the defendant’s confession was sufficiently an act of free will to purge the taint of the unlawful arrest. The Court held that the
Miranda
warnings, by themselves, could not be assumed to attenuate the taint of an unconstitutional arrest.
Brown
at 602-03,
Thus even if the statеments in this case were found to be voluntary under the Fifth Amendment, the Fourth Amendment issue remains. In order for the causal chain, between the illegal arrest and the statements made subsequent thereto, to be broken, Wong Sun requires not merely that the statement meet the Fifth Amendment standard of voluntariness but that it be “sufficiently an act of free will to purge the primary taint.” Wong Sun,371 U.S. at 486 ,83 S.Ct. at 416 [-17,9 L.Ed.2d at 454 ],

Although Tietsort’s oral declaration in the present case was a consent to a search rather than a confession, the same standards apply, requiring the State to prove that the consent was voluntary and not derived by exploitation of an earlier violation of Tietsort’s constitutional rights.
See, e.g., State v. Kerley,
In the ease before us, the district court made a factual finding, which is supported by the evidence, that before Tietsort consented to a search of outbuildings and vehicles, the officers told him that they were waiting for a search warrant to arrive. The district court also found that Tietsort’s consent to a search of his outbuildings and vehicles was voluntary. In making this finding of voluntariness, however, the court did not consider whether the officers’ assertions to Tietsort that they had discovered stolen items and could obtain a search warrant constituted an exploitation of any illegality in the prior search that tainted the consent and rendered it involuntary.
A consent is not rendered invalid merely because an officer has said that a warrant will be sought if consent is refused,
State v. Smith,
Further, the officers notified Tietsort that stolen property had already been found before they secured his consent to a second search. Confronting a suspect with evidence found in an unlawful search may constitute an exploitation of the prior illegality that taints the consent thereby induced.
See United States v. Oaxaca,
In this case, all information that the officers collected while inside Tietsort’s barn during the initial search was obtained in violation of his constitutional rights. Therefore, the officers’ assertion that they could secure a warrant was false unless the detectives saw at least the utility trailer’s serial number in open view from a vantаge point that they lawfully occupied. This misrepresentation would undermine the voluntariness of Tietsort’s consent, and the officers’ report to Tietsort that stolen property had been found would amount to such an exploitation of the illegal search as to fatally taint the consent.
The district court did not perceive that this issue was critical to the validity of Tietsort’s consent. Without discussing the officers’ representations that they had seen stolen items and could get a warrant, the district court held that Tietsort’s consent was voluntary because he approached the officers of his own volition, engaged them in conversation, and gave consent to search the outbuildings while explicitly withholding consent to search the house, and because considerable time had elapsed between the initial search and Tietsort’s contact with the officers. We defer to a trial court’s finding that a consent was voluntary if it is a reasonable inference that may be drawn from the record,
State v. Jaborra, 143
Idaho 94, 97-98,
The evidence on this point is disputed. At the hearing on Tietsort’s suppression motion, Detective Furniss testified that, from the driveway, he could discern a serial number on the cargo trailer. On cross-examination, he indicated that this number, which was black and about one and a half inches tall, was on the front of the trailer. When presented with photographs of the front of the trailer, however, he acknowledged that the number was not visible. When shown another photograph of the VIN plate, he stated that the serial number was not represented in the photograph, but that it was in large print below the plate. He also acknowledged that it may have been on the back of the trailer, which would not have been visible from outside of the barn. Detective Sarrazolla testified that he remembered seeing a small vehicle identification number plate on the side of the trailer, and acknowledged that a photograph of the front of the trailer did not show the VIN plate or any black lettering. The district court must resolve these discrepancies and make factual determinations about what the officers could or could not see within open view. 4
We must also briefly discuss Tietsort’s alternative argument that his consent was tainted because it was given while he was unlawfully detained. Where police illegally arrest an individual and contemporaneously procure his consent to a search, the events are so intertwined that the consent will not expunge the taint of the illegal arrest.
State v. Weber,
III.
CONCLUSION
On this record, we cannot determine whether the challenged evidence was unconstitutionally obtained. The constitutional integrity of Tietsort’s consent and of the subsequent warrant turns upon whether, in their initial, warrantless search of Tietsort’s property, the detectives lawfully discovered any evidence of crime in open view. The district court’s findings do not resolve this factual issue. We therefore vacate the order denying Tietsort’s suppression motion and remand this case to the district court to make the necessary findings.
Notes
. Tietsort's motion also requested suppression of evidence collected in another warrantless search *115 that was conducted several days later. The district court granted that portion of the motion.
. Tietsort argues that we should not consider the open view doctrine because the State conceded below that all of the officers’ observations during the initial search were unlawful. While the prosecutor did acknowledge that entry of the bam during the initial search was impermissible, she maintained on several occasions that the detectives lawfully could see the trailer’s serial number in open view from the driveway and presented the detectives’ testimony on this point. Later during closing arguments when defense counsel argued that the serial number was not visible from the driveway, the district court interrupted, stating that it was the court's understanding that "the state is not relying on any of that.” Defense counsel explained that in light of the prosecutor’s arguments, it was necessary to articulate why the prosecutor’s belief that the officer could view the trailer’s identification from the driveway was erroneous. At the end of the hearing, the prosecutor argued that any prior illegality was attenuated by Tietsort's consent, and she did not then reiterate the open view argument. The statements made by the prosecutor during the closing argument are confusing and did not clearly articulate whether the State was conceding that all evidence obtained during the first search was gained by an unlawful intrusion. During the evidentiary phase of the hearing, however, when Tietsort had the opportunity to respond with evidence, it is clear that the prosecutor was maintaining that thе observation of the trailer's serial number was lawful. While the confusing articulation of the scope of the State’s concession during the closing argument gives us pause, particularly in light of the apparent confusion of *117 defense counsel and the court about what arguments the State was relying upon, we are not persuaded that the State conceded anything other than the illegal entry into the bam. Even if defense counsel reasonably believed that a broader concession was made during closing argument, it could not have affected the dеfendant’s presentation of evidence, which had already been completed.
.
Miranda v. Arizona,
. The findings in the district court's memorandum decision are insufficient and may evidence some confusion on the part of the court. The district court found that police were "able to observe the identification number on a white travel trailer parked under a canopy outside the barn from the outside." This is not, however, the trailer that the officers discovered to be stolen. The officers said that they had observed a white "fifth-wheel” or "travel” type trailer under an overhanging canopy attached to the outside of the barn, but the stolen trailer was a white “Cargo Plus utility trailer" parked inside the barn itself. Both trailers are shown in photos that were placed into evidence. Because the travel trailer was not stolen, the officers' observations about it would not have contributed to probable cause for a search warrant. Furthermore, a finding that the officers could see certain numbers "from the outside” of the barn does not necessarily mean that the officers were in an area where a reasonably respectful visitor would be.
