Opinion
PALMER, J.
The sole issue presented by this appeal is whether article first, § 7, of the Connecticut constitution1 prohibits the police from subjecting a mail parcel in the possession of the United States Postal Service to a canine sniff examination by a trained narcotics detection dog based upon a reasonable and articulable suspicion that the mail contains illegal drugs. The defendant, Jamison Martin Waz, entered a conditional plea of nolo contendere, under General Statutes § 54-94a and Practice Book § 4003 (a),2 to possession of [367]*367more than four ounces of marijuana in violation of General Statutes § 2 la-279 (b)3 following the trial court’s denial of his motion to suppress marijuana found in a parcel seized from his automobile. The trial court accepted the plea and rendered judgment thereon.4 The defendant appealed from the judgment of the trial court to the Appellate Court, and we transferred the appeal to this court pursuant to Practice Book § 4023 and General Statutes § 51-199 (c). We affirm the judgment of the trial court.
The relevant facts, as set forth in the trial court’s decision on the defendant’s motion to suppress, are undisputed. “On March 24, 1994, Postal Inspector Thomas Lambert identified an Express Mail5 package addressed to Down Deep, Inc., 34-3 Shunpike Road, #104, Cromwell, CT. 06416 as fitting characteristics of the ‘drug package profile.’ This profile consists of the following characteristics: [1] [s]ize and shape of the package; [2] [wjhether the package is taped to close or [368]*368seal all openings; [3] [h]andwritten or printed labels; [4] [n] ature and destination of the package; [5] [t]he absence or presence of odors; [6] [w]hether the zip code of the sender matches that put on by the postal clerk; [7] [w]hether it contains a fictitious return address; [8] [o]rigin of the package; and [9] [t]he outward appearance of the package.
“At a suppression hearing held on September 22 and October 27,1994, Lambert testified that the Down Deep, Inc. package fit a number of characteristics relative to the drug package profile. Such characteristics included: [1] [t]he fact that the edges were taped to seal all openings; [2] [t]he package contained a fictitious return address; [3] [t]he package contained handwritten labels; [4] [i]t came from a source state, i.e., California; and [5] [t]he size and shape of the package. He further stated that the package was sent via Express Mail which, based on his seven years of training and experience as a Postal Inspector and four years experience in narcotic[s] investigations, is primarily the exclusive carrier used by individuals to transport controlled substances through the United States mail.
“It was a combination of each of these profile characteristics as well as the use of Express Mail which gave rise to Lambert’s suspicions that the parcel contained a controlled substance. He then removed the package from the mail stream and obtained a narcotics trained dog named ‘Zak’6 to externally examine the parcel. The parcel was placed among eight other similar sized parcels. Zak, however, twice alerted to the Down Deep, Inc. parcel while it was placed in different positions on the floor.
“Lambert then applied for and obtained a federal search warrant to open the package. When the search [369]*369warrant was executed, it was discovered that the package contained approximately one-half pound of suspected marijuana. A field test revealed a positive reaction for the presence of marijuana. The package was then resealed for the purpose of conducting a controlled delivery. Later that day on March 24,1994, members of the mid-state narcotics unit and Postal Inspectors Lambert and Terry Loftus began surveillance of the mail drop addressed to Down Deep, Inc. At approximately 2:28 p.m. on March 24,1994, the defendant picked up the Down Deep, Inc. package from the mail drop. Shortly thereafter, he was stopped and taken into custody. The parcel containing marijuana was seized from the right front floorboard of the vehicle the defendant was operating.” The defendant was arrested and charged with possession of marijuana and possession of marijuana with intent to sell.
The defendant moved to suppress the marijuana on the ground that the canine sniff of the parcel was a warrantless search in violation of the fourth amendment to the United States constitution7 and article first, § 7, of the Connecticut constitution. The trial court concluded that although the canine sniff was not a search within the meaning of the fourth amendment, the brief seizure of the parcel for the purpose of conducting the canine sniff required a showing of reasonable and articulable suspicion. The trial court further concluded that because the state had established that Lambert had a reasonable and articulable suspicion that the parcel contained illegal drugs, the defendant’s federal constitutional claim was without merit. The trial court declined to address the defendant’s state constitutional claim [370]*370because he had failed to provide an adequate analysis of that claim. Accordingly, the trial court denied the defendant’s suppression motion. The defendant then entered a conditional plea of nolo contendere to a substitute information charging him with possession of more than four ounces of marijuana,8 and this appeal from the trial court’s judgment of conviction followed.
On appeal, the defendant does not challenge the trial court’s conclusion that Lambert possessed a reasonable and articulable suspicion concerning the contents of the parcel. Nor does he claim that the investigation of his parcel caused any delay in its delivery or that its brief removal from the mail stream constituted an unreasonable seizure in violation of article first, § 7, of the constitution of Connecticut.9 Rather, the defendant’s sole contention is that the canine sniff of the parcel constituted a search for purposes of article first, § 7, and, therefore, that the state was required to obtain a search warrant based upon probable cause before subjecting the mail to the canine sniff.10 The state claims that the canine sniff was not a search within the meaning of article first, § 7, and, consequently, that the use of that investigative technique does not implicate the state constitutional prohibition against unreasonable [371]*371searches.11 The state further maintains that even if the canine sniff was a search within the meaning of article first, § 7, it was constitutionally permissible because Lambert had a reasonable and articulable suspicion that the parcel contained contraband.12 We need not decide whether the canine sniff of the parcel constituted a search under article first, § 7, because we conclude that even if it did, the state constitution requires no more than a showing that the investigating officers had a reasonable and articulable suspicion that the parcel contained contraband.13
[372]*372As we have indicated, the defendant concedes that Lambert had a reasonable and articulable suspicion that the parcel contained illegal drugs, and the state concedes that Lambert did not have probable cause to believe that the parcel contained contraband prior to the canine alert. Because we assume, without deciding, [373]*373that the canine sniff of the mail constituted a search for purposes of the state constitution, we must determine whether Lambert was required to obtain a search warrant based upon probable cause before subjecting the parcel to the canine sniff, as the defendant claims, or whether Lambert’s reasonable and articulable suspicion that the parcel contained contraband provided a sufficient constitutional basis for the use of that technique, as the state contends.14
“When evaluating the rights afforded to Connecticut citizens under the state constitution, we consider, to the extent applicable, six factors: (1) the text of the relevant constitutional provisions; (2) related Connecticut precedents; (3) persuasive federal precedents; (4) persuasive precedents of other state courts; (5) historical insights into the intent of our constitutional forebears; and (6) contemporary understandings of [374]*374applicable economic and sociological norms. State v. Ross, 230 Conn. 183, 249, 646 A.2d 1318 (1994), cert. denied, 513 U.S. 1165, 115 S. Ct. 1133, 130 L. Ed. 2d 1095 (1995); State v. Geisler, [222 Conn. 672, 684-86, 610 A.2d 1225 (1992)].” State v. Trine, 236 Conn. 216, 230 n.12, 673 A.2d 1098 (1996). In this case, our adjudication of the defendant’s state constitutional claim is informed principally by those federal and sister state cases involving the use of a trained narcotics detection dog.15 Our review of those precedents persuades us that the canine sniff in this case did not violate article first, § 7, of the state constitution.16
[375]*375The seminal federal case involving the use of a trained narcotics detection dog is United States v. Place, 462 U.S. 696, 707, 103 S. Ct, 2637, 77 L. Ed. 2d 110 (1983), wherein the United States Supreme Court concluded that a canine sniff of luggage briefly detained upon reasonable suspicion in a public airport “[does] not constitute a ‘search’ within the meaning of the Fourth Amendment.”17 See also United States v. Jacobsen, 466 U.S. 109, 123-24, 104 S. Ct. 1652, 80 L. Ed. 2d 85 (1984).18 In concluding that the use of the canine sniff technique in those circumstances did not constitute a search requiring probable cause, the Place court stated that “[a] ‘canine sniff by a well-trained narcotics detection dog . . . does not require opening the luggage. It does not expose noncontraband items that otherwise would [376]*376remain hidden from public view, as does, for example, an officer’s rummaging through the contents of the luggage. Thus, the manner in which information is obtained through this investigative technique is much less intrusive than a typical search. Moreover, the sniff discloses only the presence or absence of narcotics, a contraband item. Thus, despite the fact that the sniff tells the authorities something about the contents of the luggage, the information obtained is limited. This limited disclosure also ensures that the owner of the property is not subjected to the embarrassment and inconvenience entailed in less discriminate and more intrusive investigative methods. . . . We are aware of no other investigative procedure that is so limited both in the manner in which the information is obtained and in the content of the information revealed by the procedure.” United States v. Place, supra, 707.
For the reasons enumerated in Place, federal courts are unanimous in concluding that the fourth amendment is not violated when police briefly detain a piece of mail suspected of containing illegal drugs for the purpose of subjecting it to an examination by a trained narcotics detection dog. See, e.g., United States v. Banks, 3 F.3d 399, 402 (11th Cir. 1993), cert. denied, 510 U.S. 1129, 114 S. Ct. 1097, 127 L. Ed. 2d 410 (1994) (package sent via Express Mail); United States v. Aldaz, 921 F.2d 227, 229-31 (9th Cir. 1990), cert. denied, 501 U.S. 1207, 111 S. Ct. 2802, 115 L. Ed. 2d 975 (1991) (package sent via United States mail using express delivery); United States v. Lux, 905 F.2d 1379, 1381-82 (10th Cir. 1990) (package sent via Express Mail); United States v. LaFrance, 879 F.2d 18 (1st Cir. 1989) (package sent via Federal Express); United States v. Mayomi, 873 F.2d 1049, 1053-54 (7th Cir. 1989) (mail received at private mail box); Garmon v. Foust, 741 F.2d 1069, 1072-73 (8th Cir. 1984) (mailed package received at dormitory); United States v. Martinez, 869 F. Sup. 202, [377]*377205-207 (S.D.N.Y. 1994) (packages sent via Express Mail); United States v. Dillon, 810 F. Sup. 57, 61 (W.D.N.Y. 1992) (parcels shipped via United Parcel Service); United States v. Cantrall, 762 F. Sup. 875, 878-80 (D. Kan. 1991) (package sent via Express Mail); United States v. Sklar, 721 F. Sup. 7, 14 (D. Mass. 1989) (package sent via Express Mail), rev’d in part on other grounds, 920 F.2d 107 (1st Cir. 1990) ; United States v. Holden, Docket No. 88-20105-01, 1989 U.S. Dist. LEXIS 1144, *5 (D. Kan. Jan. 9, 1989) (package sent via Express Mail); United States v. Mena, Docket No. 86-CR-524, slip. op. (N.D. Ill. Oct. 20, 1986) (package shipped via United Parcel Service).19
State courts are similarly in accord, under their respective state constitutions, that the police need no more than a reasonable and articulable suspicion to justify the use of the canine sniff technique on an object that has been briefly detained for that purpose. A number of state courts have concluded that a canine sniff is not a search for state constitutional purposes and, [378]*378consequently, that a judicial determination of probable cause prior to subjecting the item to an examination by a trained narcotics detection dog is unnecessary. See, e.g., People v. Mayberry, 31 Cal. 3d 335, 337, 644 P.2d 810, 182 Cal. Rptr. 617 (1982) (luggage in airport); Daniels v. Cochrane, 654 So. 2d 609, 612-13 (Fla. App. 1995) (package sent via Federal Express); O’Keefe v. State, 189 Ga. App. 519, 526, 376 S.E.2d 406 (1988) (automobile); State v. Snitkin, 67 Haw. 168, 173, 681 P.2d 980 (1984) (package at Federal Express office); State v. Cancel, 256 N.J. Super. 430, 436-37, 607 A.2d 199 (1992), cert. denied, 134 N.J. 484, 634 A.2d 530 (1993) (routine use of dogs to detect narcotics at public airports); State v. Villanueva, 110 N.M. 359, 362-63, 796 P.2d 252 (N.M. App.), cert. denied, 110 N.M. 260, 794 P.2d 734 (1990) (luggage at border checkpoint); State v. Waldroup, 100 Ohio App. 3d 508, 514, 654 N.E.2d 390 (1995) (automobile); State v. Palicki, 97 Ohio App. 3d 175, 181-82, 646 N.E.2d 494 (1994) (automobile); State v. Stanphill, 53 Wash. App. 623, 630-31, 769 P.2d 861 (1989) (package sent via Express Mail); State v. Boyce, 44 Wash. App. 724, 730, 723 P.2d 28 (1986) (safety deposit box). Moreover, the vast majority of state courts that have determined that the use of a trained narcotics detection dog constitutes a search for state constitutional purposes have also concluded that, because of the search’s relatively unintrusive, contraband-specific nature, no more than a reasonable and articulable suspicion is required to justify the search. See, e.g., McGahan v. State, 807 P.2d 506, 510-11 (Alaska App. 1991) (exterior of warehouse); Pooley v. State, 705 P.2d 1293, 1311 (Alaska App. 1985) (luggage checked with airline); People v. May, 886 P.2d 280, 281 (Colo. 1994) (package sent via Express Mail); People v. Boylan, 854 P.2d 807, 811 (Colo. 1993) (package sent via Federal Express); People v. Unruh, 713 P.2d 370, 377-78 (Colo.), cert. denied, 476 U.S. 1171, 106 S. Ct. 2894, 90 L. Ed. 2d 981 (1986) [379]*379(safe in police custody); State v. Pellicci, 133 N.H. 523, 534-35, 580 A.2d 710 (1990) (automobile); People v. Dunn, 77 N.Y.2d 19, 25-26, 564 N.E.2d 1054, 563 N.Y.S.2d 388 (1990), cert. denied, 501 U.S. 1219, 111 S. Ct. 2830, 115 L. Ed. 2d 1000 (1991) (common hallway outside defendant’s apartment door); Commonwealth v. Johnston, 515 Pa. 454, 462-64, 530 A.2d 74 (1987) (rented storage locker); cf. People v. Offen, 78 N.Y.2d 1089, 1091, 585 N.E.2d 370, 578 N.Y.S.2d 121 (1991) (even if canine sniff of package shipped by United Parcel Service was search, it was justified by reasonable and articulable suspicion); State v. Kosta, 75 Or. App. 713, 719, 708 P.2d 365 (1985) (even if canine sniff of package sent via Federal Express was search, it was justified by reasonable and articulable suspicion), aff'd on other grounds, 304 Or. 549, 748 P.2d 72 (1987); but see Commonwealth v. Martin, 534 Pa. 136, 143, 626 A.2d 556 (1993) (probable cause required for canine sniff of satchel being carried by suspect). Thus, the overwhelming weight of federal and sister state authority supports the state’s contention that a canine sniff examination of a mail parcel briefly detained upon reasonable and articulable suspicion does not run afoul of constitutionally protected privacy rights.20
[380]*380The defendant relies primarily on United States v. Thomas, 757 F.2d 1359 (2d Cir. 1985), cert. denied, 474 U.S. 819, 106 S. Ct. 66, 88 L. Ed. 2d 54 (1985), and Commonwealth v. Martin, supra, 534 Pa. 136, to support his claim that the canine sniff of his parcel required a search warrant based upon probable cause. In Thomas, the Court of Appeals for the Second Circuit concluded that a canine sniff conducted outside the defendant’s apartment constituted an unreasonable search in violation of the fourth amendment and, therefore, that the warrant authorizing the search of the apartment was defective because it was predicated upon the fact that the dog had alerted to the presence of drugs. United States v. Thomas, supra, 1366-67. The court distinguished the case before it from United States v. Place, supra, 462 U.S. 696, concluding that because an individual has a heightened privacy interest in his or her dwelling place, the canine sniff technique is more intrusive of a person’s privacy rights when it is employed at one’s home than when it is used in a public airport.21 United States v. Thomas, supra, 1366.
[381]*381Similarly, in Martin, the Supreme Court of Pennsylvania concluded that probable cause was required under the Pennsylvania constitution before the police could conduct a canine sniff of a satchel being carried by a suspected drug dealer. Commonwealth v. Martin, supra, 534 Pa. 143. Previously, in Commonwealth v. Johnston, supra, 515 Pa. 465-66, the Pennsylvania Supreme Court had concluded that a canine sniff for the presence of drugs in a storage locker was a search for state constitutional purposes requiring reasonable and articulable suspicion. In Martin, the court distinguished Johnston as involving the use of a canine sniff to search a place rather than a person. Commonwealth v. Martin, supra, 142-43. Relying on the fact that the defendant had been carrying the satchel when the police detained him and seized the bag for the purpose of subjecting it to the canine sniff, the court in Martin, noting that “an invasion of one’s person is, in the usual case, [a] more severe intrusion on one’s privacy interest than an invasion of one’s property,” concluded that the search was subject to the higher standard of probable cause. Id. Because both Thomas and Martin are based on the heightened privacy interests that pertain to one’s house or person, neither case advances the defendant’s claim that a prior judicial determination of probable cause is required for a canine sniff of a parcel placed in the mail.22 See, e.g., United States v. Sklar, supra, 721 F. Sup. 14 (“the [cjourtis convinced that the privacy interest asserted by [the defendant in his Express Mail package] is more akin to that suggested by the [United [382]*382States] Supreme Court in Place [luggage] [rather] than that discussed by the Second Circuit in Thomas [apartment]”); State v. Phaneuf, 597 A.2d 55, 58 (Me. 1991) (“[w]e reject [the defendant’s] contention that the fourth amendment creates a heightened expectation of privacy in the mail akin to that in one’s domicile” [emphasis in original]).
The defendant also maintains that his claim finds support in a number of United States Supreme Court and United States Court of Appeals cases recognizing a right to privacy in letters or parcels sent through the mail.23 We agree with the defendant that he retained a legitimate expectation of privacy, under both the state and the federal constitutions, in the parcel of mail that Lambert caused to be subjected to the canine sniff. See Washington v. Meachum, 238 Conn. 692, 723, 680 A.2d 262 (1996) (article first, § 7, requires determination of whether party claiming infringement of right to privacy has manifested subjective expectation of privacy and, if so, whether that expectation is one society is prepared [383]*383to recognize as reasonable); State v. Joyce, 229 Conn. 10, 20, 639 A.2d 1007 (1994) (same). The cases cited by the defendant, however, were all decided before Place and contemplate a warrantless opening of the mail by the police to inspect its contents, rather than an examination of the air outside the parcel by a trained narcotics detection dog.24 Because the defendant’s privacy rights in his parcel derive primarily from the recognized community interest in ensuring that the state does not intrude unreasonably upon the contents of such items, we reject the defendant’s claim that the external, olfactory examination of his parcel by a trained narcotics detection dog entitled him to the same level of constitutional protection to which he would have been entitled had the police sought to open and inspect the parcel. Accordingly, we are satisfied that even if a canine sniff examination of a mail parcel in the possession of the United States Postal Service implicates our state constitutional prohibition against unreasonable searches, the [384]*384use of the technique was permissible in this case because it was minimally, if at all, intrusive of the defendant’s legitimate privacy rights, and the officer conducting the canine sniff had a reasonable and articu-lable suspicion that the parcel contained illegal drugs.25 We therefore reject the defendant’s claim that the trial court improperly denied his motion to suppress the marijuana seized from his automobile.
The judgment is affirmed.
In this opinion BORDEN, NORCOTT and PETERS, Js., concurred.
