Ronald Dale Dunn and Robert Lyle Carpenter were found guilty by a jury of conspiring to manufacture phenylacetone and amphetamine, and to possess amphetamine with intent to distribute, in violation of 21 U.S.C. § 846. Dunn also was convicted for manufacturing the two controlled substances and for possessing amphetamine with intent to distribute. 21 U.S.C. § 841(a)(1). The jury convicted Carpenter of aiding and abetting Dunn in the unlawful manufacturing and possessing. 18 U.S.C. § 2.
Carpenter challenges the sufficiency of the evidence supporting his convictions, particularly that which ties him to Dunn’s activities. We are not persuaded; Carpenter’s convictions are affirmed. Dunn appeals the trial court’s refusal to suppress physical evidence, obtained as a result of warrantless searches of his ranch near Johnson City, Texas, and certain statements he made after arrest. Finding merit in this assignment of error, we reverse and remand.
Background Facts
A careful marshalling of the facts usually is required for appellate review for few, if any, legal questions may be resolved in a factual vacuum. Detailing of facts is particularly critical in cases in which the controlling precedent is less than precise and the perceived distinguishing features are less than overwhelming. The case before us belongs in that category, for in its resolution we are propelled into the amorphous realm of constitutional discussion subtitled “reasonable expectations of privacy.” Our task in this context is to separate that which falls within the aegis of this fourth amendment buckler from that which does not.
See, e.g., Rakas v. Illinois,
The factual scenario began in the summer of 1980 with the surveillance of Carpenter, in and around the Houston, Texas area, by agents of the Drug Enforcement Administration (DEA). Carpenter was accumulating large quantities of chemicals and equipment used in the manufacture of controlled substances, particularly amphetamine and phenylacetone. Some of the purchases were made in his name, some were made in the name of Omega, Inc., a corporation of which he was president, and some *1096 were made under the alias “Jack Carter.” The equipment acquired included several hot plate stirrers.
A hot plate stirrer is an electric heating device that applies heat to a container and, by use of a built-in magnet, stirs the contents. Stirrers are used in the “cooking” of chemicals.
When Carpenter placed his order for stirrers, DEA Agent Robert Surovec secured a warrant from a Texas state judge authorizing the installation and operation of an electronic beeper in a stirrer. The beeper was installed and activated. Thereafter, on September 3, 1980, Carpenter took possession of the rigged stirrer and was tracked to his residence in Spring, Texas. A few days later the signal from this beeper was lost, to be re-discovered in early November 1980, on Dunn’s ranch in Blanco County, Texas.
In the meantime, DEA Agent Ronald Gospodarek secured the installation of a beeper in a 55 gallon plastic drum which was to be used to deliver acetic anhydride ordered by Carpenter. Simultaneously, plans were completed to install a beeper in a container filled with 100 pounds of pheny-lacetic acid, a precursor to phenylacetone, which Carpenter had ordered. Warrant authorization was granted by state authorities. Thereafter, the drum and container, laden with the chemicals and beepers, were delivered to Carpenter.
The drum and container beepers were monitored from October 27, 1980 until November 5, 1980. On the latter date, Gospo-darek and other officers, homing on the container beeper, trailed Carpenter, driving a pickup truck, from Houston to Ronald and Betty Dunn’s ranch near Johnson City, Texas. Aerial surveillance disclosed the truck backed up to a barn behind the ranch residence, apparently for the unloading of its contents. It was at this time that the hot plate stirrer beeper, lost in early September, was detected. It, too, was on the ranch property.
On the afternoon of November 5, 1980, DEA agents took aerial photographs of the ranch. The photographs showed a ranch house set back approximately lh mile from a public road, at the end of a private driveway, a smaller house immediately next to the main residence, a windmill, a water tank, and two barns approximately 50 yards behind the house. The residence enclave was surrounded by trees and the ranch acreage was circled by a perimeter fence. There were several interior fences near the buildings and at other locations. The private driveway was secured by a locked chain.
Around 9:00 p. m. on the night of November 5, 1980, after studying the photographs, Gospodarek and Officer Martin Fite of the Houston Police Department crossed the perimeter fence and approached the confines containing the buildings. They became disoriented in the dark but eventually came to the driveway leading to the residence. They went to a fence at the rear of the ranch house and there detected a strong odor of phenylacetic acid. 1 Crossing another fence, they looked into one pole barn and saw only empty boxes. Then they walked under the tin overhang of the second barn, up to a closed gateway. With the aid of their flashlights, they looked through the barn’s openings and noted its contents. They saw chemicals and chemical equipment in a setting taken to be a phenylace-tone laboratory.
Their mission completed, Gospodarek and Fite withdrew. Shortly afterwards, Gospodarek telephoned Surovec and reported the findings. Adding this information to that already in hand, Surovec began preparing an affidavit for a warrant to search the ranch. 2 The drafting was completed on November 6, 1980.
*1097 On two occasions on November 6, 1980, officers made entry into the ranch and inspected the buildings. In the early afternoon, Gospodarek, accompanied by DEA Agent Fred Thomas, returned to see in daylight what had been observed by flashlight. They had no warrant authorization, although Agent Surovec was in the process of preparing the supporting affidavit. While on the property, they installed one electronic surveillance device on the private drive, just off the public road, and another on the gate of the barn housing the laboratory. The devices were placed on Dunn’s property without prior warrant authorization. 3
At approximately 6:00 p. m. that same day, Surovec completed preparation of the warrant affidavit and, accompanied by DEA chemist Buddy Goldston and DEA technician Wayne Moody, he presented the warrant request to a federal magistrate. A warrant to search the Dunn ranch was issued at 8:30 p. m. on the night of November 6, 1980.
While Surovec was requesting the warrant from the magistrate, Gospodarek, accompanied by other agents, again made entry. Gospodarek looked for vehicles or persons. He also checked the suspect barn before withdrawing.
On the night of November 7, 1980, Gold-ston and Fite again entered the Dunn property. This was the first post-warrant visit to the ranch. They made no effort to effect seizures pursuant te the warrant, despite the claim of exigent circumstances set forth in the affidavit, 4 but merely observed the laboratory and departed.
At approximately 10:00 a. m. on November 8, 1980, the warrant was executed. DEA agents, accompanied by state law enforcement personnel, drove to the ranch and found Dunn. Officer Fite, armed with a shotgun, arrested Dunn, placed him in handcuffs, and escorted him into the ranch house while other officers loaded the chemicals and equipment and searched the premises.
Dunn was informed of his Miranda rights. 5 Thereafter, in response to a ques *1098 tion whether any controlled substances were in the house, he directed the officers to a closet which contained bags of amphetamine. 6
The Fourth Amendment Conundrum
The fourth amendment challenge to the evidence obtained from the execution of the search warrant, as well as to the evidence resulting from the earlier visits to the ranch, squarely presents the elusive expectation of privacy issue. If Dunn’s fourth amendment protections were abrogated by the entries on November 5 and 6, the evidence discovered at that time and later seized pursuant to the warrant 7 must be excluded and Dunn’s convictions must be set aside. That same reasoning does not apply to Carpenter since he cannot assert a legitimate expectation of privacy in any place searched or item seized. 8
Although not specifically enumerated in the Constitution, the right of privacy long has been recognized.
9
Property interests once were considered paramount in fourth amendment applications.
See, e.g., Goldman v. United States,
Dunn maintains that he held a reasonable expectation of privacy over his ranch property and the buildings thereon, particularly the barn and its contents. Evaluation of this contention requires a close look at several essential facts.
The ranch, modest in size for that area of Texas, is approximately 198 acres, and is encircled by a perimeter fence. The residence and the other buildings are in a small clearing almost entirely surrounded by trees. The house and the barns are not visible from the farm to market road; they are not visible from the perimeter fence. There are interior fences, including one around the residence and one around the subject barn. Once inside the perimeter fence, it is necessary to penetrate at least one more fence before reaching the place where the officers stood while examining the interior of the barn.
We commence our legal analysis, mindful of the basic constitutional rule that “ ‘searches conducted outside the judicial process, without prior approval by judge or magistrate, are
per se
unreasonable under the Fourth Amendment — subject only to a few specifically established and well-delineated exceptions,’ ”
Coolidge
v.
New Hampshire,
In
Williams,
agents of the Bureau of Alcohol, Tobacco and Firearms (ATF), acting on a tip, visited a site in rural Mississippi which was suspected of housing a “still.” The still could not be seen from the public roadway and the agents walked along a perimeter fence, approaching the outbuildings on the property. From the edge of an old fence, outside the curtilage of the farmhouse and perhaps off the subject property, the agents “detected the odor of moonshine liquor and fermented mash coming from the direction of the hogpen.”
In
Williams,
we recognized that the expectation of privacy test “has done away with outmoded property concepts no longer satisfactory for fourth amendment analysis,”
id. (citing The Supreme Court, 1967 Term,
82 Harv.L.Rev. 63, 189 (1968)), but noted that “the distinction between open fields and curtilage is still helpful in determining the existence or not of reasonable privacy expectations.”
Id. (citing
Note, 76 Mich.L.Rev. 154 (1977)). We further remarked “that open fields surrounding a house are not protected under the fourth amendment and that a search of them need not be accompanied by a warrant issued upon probable cause.”
Id. (citing United States v. Brown,
We concluded that the protected curti-lage extended to the shed in question and held that:
as to outbuildings that are not encompassed by a fence that also includes the house, or perhaps a privacy or exclusionary one around them, the outer limits of the curtilage are defined by the walls of the remote outbuildings.
Shortly after we rendered our Williams decision the Supreme Court announced Rakas v. Illinois. We disagree with the suggestion that the decisions are in conflict. Because the boundaries of the farm in Williams were not marked, and because the only manifestation of a privacy assertion or a proprietary exclusion was a broken down fence, subjective privacy expectations were lacking. Thus, the Williams decisional methodology comports fully with the guide established in Rakas.
By contrast, the fence around Dunn’s ranch was complete and intact. The barn itself was circled by another substantial fence. Under
Williams
and earlier jurisprudence, see
Walker v. United States,
Probable Cause and Exigent Circumstances
The government makes a compelling argument that it had probable cause to act, a contention supported by the factual background of the case. The following factors all tend to bolster the reasonable belief that a criminal offense had been or was being committed: the accumulation of equipment and large quantities of chemicals, all purchased with cash and some acquired under a false name; the tracking of the chemicals to the Dunn ranch; the detection of the lost hot plate stirrer beeper signal on the Dunn property; Dunn’s prior criminal record; and the remote location of the ranch. Accepting that probable cause to search the ranch property existed on November 5 and 6, a search warrant was mandatory unless exigent circumstances excused that constitutional requirement.
*1101
In support of the claim that exigent circumstances validated the warrantless searches, the government relies on
United States v. Villarreal,
But that was not the circumstance in the case at bar. The law enforcement officers were trespassing, having crossed a perimeter fence prior to detecting the suspicious odor. In addition to that basic dissimilarity, the odor detected was not that of a contraband. The officers in the
Villarreal
line of cases smelled a controlled substance; the DEA agent on Dunn’s ranch smelled a legal chemical, phenylacetic acid. Even if it had been the odor of contraband, the occurrence of the trespass before the detection would vitiate the use of this information. A release from fourth amendment requirements cannot be based on fourth amendment violations.
See, e.g., Delaware v. Prouse,
The cited cases are subject to a further, critical distinction: they all involve an automobile. While motor vehicles and other means of transportation are protected by the fourth amendment, 13 they receive markedly different treatment. 14 Notably, the Supreme Court has observed:
this Court has recognized significant differences between motor vehicles and other property which permit warrantless searches of automobiles in circumstances in which warrantless searches would not be reasonable in other contexts.... The answer lies in the diminished expectation of privacy which surrounds the automobile. . . .
United States v. Chadwick,
The contention that exigent circumstances existed in the present case is belied by the facts perceivable at the time, confirmed with the 20/20 visual acuity of hindsight. 16 Although the agents expressed concern that the laboratory might be dismantled and moved before a warrant could be obtained, this argument is not persuasive. The area was remote. Access was limited, particularly vehicle ingress and egress. In addition, the ranch property was subject to surveillance readily from both the ground and the air.
Moreover, in light of the actions of the agents, the protestations of urgency, including those recited in the warrant affidavit, are not convincing. Although obtained on the night of November 6, 1980, the warrant was not executed until approximately 10:00 a. m. on November 8, despite the entry of agents on November 7. The necessity for swift action, which purportedly justified the warrantless entries on November 5 and 6, is not apparent in the officers’ post-warrant conduct.
The government bears the burden of justifying a warrantless search.
United States v. De LaFuente,
Dunn’s Statements
In determining whether Dunn’s inculpatory statements uttered shortly after his arrest on November 8 must be excluded from evidence, we are guided by the teachings of
Wong Sun v. United States,
We are aware of no bright-line formula to resolve the dilemma and we are mindful that “[n]ot every fruit that grows from poisonous trees is constitutionally lethal.”
United States v. Vicknair,
Evaluating the standards for application of the exclusionary rule to live-witness testimony ..., we are first impelled to conclude that the degree of free will exercised by the witness is not irrelevant in determining the extent to which the basic purpose of the exclusionary rule is advanced by its application. This is certainly true when the challenged statements are made by a putative defendant after arrest, Wong [v. United States,371 U.S. at 491 ,83 S.Ct. at 407 ]; Brown v. Illinois [422 U.S. 590 , 603,95 S.Ct. 2254 ,45 L.Ed.2d 416 (1975) ], and a fortiori is true of testimony given by nondefendants.
We are in accord with the analysis of our colleagues of the Ninth Circuit who distinguished “the ‘live witness’ testimony of a potential co-defendant . . . [from] that of a witness not arrested and not implicated in the criminal activities at issue.”
United States
v.
Humphries,
Carpenter — Sufficiency of the Evidence
Carpenter contends that the evidence is insufficient to sustain his convictions. We disagree. Viewing the evidence in the light most favorable to the government,
see, e.g., Glasser
v.
United States,
The convictions of Robert Lyle Carpenter are AFFIRMED.
The convictions of Ronald Dale Dunn are REVERSED and the matter is REMANDED for further proceedings not inconsistent herewith.
Notes
. Gospodarek initially testified at the suppression hearing that he was unaware that he was on Dunn’s property when he first noted the odor of phenylacetic acid. That he was on Dunn’s ranch, however, is established beyond doubt by his further testimony and the other evidence. See note 2, infra.
. Surovec’s affidavit stated:
At about 10:55 p. m., on November 5, 1980, Agent Gospodarek telephonically advised me *1097 that he and Houston Police Officer Martin Fite had walked down a fence line south of the farm which separates Dunn’s property from adjacent property. At this time, Agent Gospodarek related to me that he and Officer Fite had smelled a strong chemical odor which indicated to Agent Gospodarek that phenylacetone was being manufactured. Agent Gospodarek and Officer Fite then crossed over the fence and approached the barn-like structure at the rear of the house and at this time observed, with the use of flashlights, that one side of the barn was open and that inside the barn there were three large flasks in a refluxing stage.
Surovec’s affidavit continued:
On the evening of November 5, 1980, Agent Gospodarek telephonically advised me that he had determined through the Blanco Courthouse and through Game Warden Warren Guthrie that the farm consisted of 198.1 acres and had been purchased by Ronald D. Dunn in February 1980.
It is clear from testimony at the suppression hearing that the affidavit contains several misstatements. Although the errors are apparent, the warrant issued on the evening of November 6, 1980 is not invalid for this reason. “Under the holdings in
Franks v. Delaware,
. The electronic sensors were not designed to intercept conversations. They were placed near the driveway and on the barn gate to detect the passage of vehicles or persons.
. The warrant affidavit reads:
Affiant states that the contraband in the instant case is such that it can be easily destroyed and that since the illicit manufacture of phenylacetone, amphetamine and methamphetamine is a process taking several hours and often conducted through the nighttime hours as well as the daytime, affiant requests authority to execute at any time (day or night).
. Under
Miranda v. Arizona,
. A dispute exists whether Dunn asserted or waived his right to the presence of counsel before speaking. Dunn’s account is supported by the testimony of one agent who recalled that Dunn said he would “like to talk to his lawyer prior to making a decision.” It is possible that Miranda and its progeny may have compelled the cessation of questioning. We do not decide that issue, however; our disposition of the appeal makes the resolution of this question unnecessary.
. The bulk of the warrant affidavit was composed with information obtained as a result of the warrantless entries on November 5 and 6.
. Carpenter neither enjoyed nor claimed any possessory or proprietary interest in the Dunn ranch or in the items found therein. In
United States
v.
Salvucci,
. Writing in another context, Justice Blackmun noted that while the
Constitution does not explicitly mention any right of privacy ... a line of decisions . . . going back ... as far as Union Pacific R. Co. v. Botsford,141 U.S. 250 , 251,11 S.Ct. 1000 [1001]35 L.Ed. 734 (1891) ... has recognized that a right of personal privacy, or a guarantee of certain ... zones of privacy does exist under the Constitution. In varying contexts, the Court . .. found .. . the roots of that right in the First Amendment . . .; in the Fourth and Fifth Amendments ...; in the penumbras of the Bill of Rights, ... in the Ninth Amendment ...; or in the concept of liberty guaranteed by the first section of the Fourteenth Amendment....
Roe v. Wade,
. Justice Brandéis’ Olmstead dissent provides a more modern perspective of the intent of the framers in drafting the fourth amendment:
They conferred, as against the Government, the right to be let alone — the most comprehensive of rights and the right most valued by civilized men. To protect that right, every unjustifiable intrusion by the Government upon the privacy of the individual, whatever the means employed must be deemed a violation of the Fourth Amendment.
. In invigorating the phrase “reasonable expectation of privacy,” the Supreme Court has suggested that a weighing of the government’s interest in the public health and welfare against the individual’s rights is required. A balance of competing interests has been referred to as the “ready test for determining reasonableness.”
Terry v. Ohio,
. The
Williams
court noted that “the government unaccountably concedes standing.”
.
See, e.g., Delaware v. Prouse,
.
See, e.g., New York v. Belton,
. The “inherent mobility of automobiles creates circumstances of such exigency that, as a practical necessity, rigorous enforcement of the warrant requirement is impossible.”
South Dakota v. Opperman,
. The determination of probable cause and exigent circumstances must be based on the circumstances as they existed at the time of the challenged action, and must be viewed from the perspective then obtaining. Our reference to hindsight in no way modifies that well-established rubric.
. The “independent source” doctrine which also excuses the exclusion of certain evidence,
see, e.g., Silverthorne Lumber Co. v. United States,
