Defendant-appellant Wayne O. Sowers challenges his conviction for possession of cocaine with intent to distribute, see 21 U.S.C. § 841(a)(1), (b)(1)(B), and (b)(1)(C) (1994), by resurrecting some — -but not all — of the arguments advanced in his unsuccessful motion to suppress evidence. 1 In service of this end, the appellant argues that the trial court erred in concluding that neither the detention of the appellant and of a passenger in the vehicle that he was driving nor a warrantless search of the appellant’s jacket, worn by the passenger, produced a cognizable constitutional insult. Concluding, as we do, that the district court properly denied the appellant’s pretrial suppression motion, we affirm the judgment of conviction.
I. BACKGROUND
On September 21, 1996, at approximately 10:00 p.m., Maine State Trooper Kevin Curran was traveling northbound along a desolate stretch of the Maine Turnpike. While passing a Toyota, he noticed a loud noise emanating from the vehicle’s exhaust system. His interest piqued, Curran also observed a missing front license plate. He slowed and activated his cruiser’s blue flashing lights. The Toyota stopped in the breakdown lane.
Curran approached the vehicle from the rear and asked the operator (Sowers) for his papers. Sowers produced a valid license, along with a registration listing Tammy Gay-ton as the Toyota’s owner. "When Curran asked the young woman seated next to Sowers to produce some form of identification, she responded that she was Tammy Gayton, but acknowledged that she had nothing on her person to confirm that fact. Unsure as to the passenger’s true identity, Curran instructed her to exit the vehicle and instructed Sowers to remain seated. Both complied.
After physically separating the two occupants, Trooper Curran noticed that they both appeared extremely nervous. He thus questioned each of them as to the extent, purpose, and details of their travels. When substantial discrepancies developed, his suspicions heightened.
Curran asked the woman to remain standing next to his police cruiser while he initiated a cursory background check, endeavored to verify her identity, and prepared citations for the defective muffler, see. Me. Rev.Stat. Ann. tit. 29-A § 1912(1), (4) (West 1993), and the missing license plate, see id. § 452(a) (West 1987). The background check revealed that Sowers’s driver’s license was valid and that the Toyota was duly registered to Gayton. Curran also obtained a rough physical profile of Gayton, which seemed to match the woman whom he had detained.
Despite receipt of this information, Curran remained dissatisfied with the conflicting answers that he had received in response to his earlier questioning. He apprised Gayton of his lingering suspicions and sought permission to search her vehicle. Gayton initially refused to consent to a search, but eventually relented after Curran informed her that he would summon a narcotics dog to perform a *26 sniff-search. After giving her written consent to the vehicle search, Gayton’s anxiety became more pronounced.
Before attempting to search the vehicle, Curran radioed for assistance. While awaiting backup, Curran performed a pat-down search of Gayton’s person. In the course of that search, he felt a hard, cylindrical object through the material of the jacket she was wearing. Curran queried Gayton about the item, but she disclaimed any knowledge, stating that neither the jacket nor its contents belonged to her. Curran removed the object from the jacket pocket. It proved to be a package containing a substance similar in appearance and consistency to cocaine. Curran promptly arrested both Sowers (age 42) and Gayton (age 18).
Trooper Frank Holcomb arrived on the scene at approximately 10:40 p.m. and Curran then searched the Toyota. He found no contraband. After the troopers transported the two suspects to the Androscoggin County Jail, Sowers admitted that he had traveled to Massachusetts and bought quantities of both powdered and crack cocaine.
II. PROCEEDINGS BELOW
On October 10, 1996, a federal grand jury returned an indictment that charged Sowers with possessing or conspiring to possess powdered and crack cocaine, with intent to distribute. The appellant moved to suppress the evidence seized during and after the roadside events. He argued, inter alia, that the protracted investigative stop constituted an unlawful detention, and that in all events the pat-down search was unjustified. He also sought to exclude the incriminating statements made by him while in custody on the ground that those statements were the fruits of an illegal detention.
Following an evidentiary hearing, the district court denied the suppression motion. See
United States v. Sowers,
In short order, a jury found the appellant guilty on two counts of the indictment. 3 The district court sentenced Sowers to a 46-month term of imprisonment. This appeal followed.
III. DISCUSSION
In addressing orders granting or denying suppression, we scrutinize the trial court’s factual findings for clear error and subject its ultimate constitutional conclusions to plenary review.
See Ornelas v. United States,
A
We open our discussion of the merits by addressing the appellant’s charge that the officer’s detention of the motorists amounted to a
de facto
arrest. Sowers carefully cabins this argument. He does not contest Judge Carter’s finding that the initial stop, for admitted equipment violations, was justified. He argues instead that the length and tenor of the detention at some point transmogrified a lawful
Terry
stop,
see Terry v. Ohio,
The government says that Sowers lacks standing to voice much of this plaint. A defendant ordinarily cannot base a constitutional claim on a violation of a third person’s rights.
See Rakas v. Illinois,
Nonetheless, there is more to Sowers’s challenge than meets the prosecution’s eye. Once the police halt a vehicle on the highway, both the driver and the passengers are in a practical sense subject to the officers’ authority.
See Whren v. United States,
On this issue, the appellant acknowledges that
Terry
sanctions a brief detention of an individual to confirm or allay a police officer’s reasonable suspicions. 392 U.S. at. 20-21,
The effort to locate a particular sequence of events along the continuum of detentions begins with a determination as to whether the officer’s actions were justified at the inception.
See Terry,
On this question, the district court supportably found that Curran’s level of warranted suspicion gradually escalated as his encounter with Sowers and Gayton progressed. Based on unfolding events, the trooper’s attention (and, thus, his reasonable suspicions) shifted away from the equipment violations that prompted the initial stop toward a belief that the detainees were engaged in more serious skulduggery. Such a shift in focus is neither unusual nor impermissible.
See, e.g., Zapata,
By the same token, we are not inclined to hold that Trooper Curran, in acting on these suspicions, perpetrated an impermissible
defacto
arrest. In assaying such a claim, a court must weigh, among other factors, the length of the detention, the restrictions placed on an individual’s personal movement, the force (if any) that was exerted, the information conveyed to the detainee, and the severity of the intrusion.
See McCarthy,
To sum up, the Supreme Court has cautioned that reasonable suspicion, like probable cause, is not amenable to technical formulations that purport to identify the precise types of conduct or sets of circumstances that will or will not permit a police officer to stop and detain an individual.
See Ornelas,
B.
The appellant also challenges the pat-down search of Gayton, and in particular, the search of a jacket that he owned which Gayton was wearing at the time. The district court rejected this challenge. Relying on
Frazier v. Cupp,
The fundamental flaw in the appellant’s argument is that it misapprehends the character of a
Terry
stop. The pat-down search that a
Terry
stop entails is a search of the person.
See Terry,
IV. CONCLUSION
We need go no further. Having combed the record, we are fully persuaded that the district court did not err in denying Sowers’s motion to suppress. The judgment of conviction must therefore be
Affirmed.
Notes
. To the extent that arguments made at the suppression hearing are not renewed on appeal, we deem them abandoned.
See United States v. Zannino,
. Although use of the term "standing” in this context may offend a legal purist, we have employed that word as "a shorthand method of referring to the issue of whether the defendant's own Fourth Amendment interests were implicated by the challenged governmental action.”
United States v. Sanchez,
. The government had brought, and thereafter dropped, a conspiracy count.
. The appellant suggests that Curran's mention of a canine sniff-search amounted to a threat, and thus was a show of force. This argument never takes wing, however, because that conversation took place with Gayton, out of Sowers’s earshot. Absent any communication, the “threat” could not have constituted a show of force as to Sowers.
