Facts
- DEA agents at Detroit Metropolitan Airport observed Sylvia Mendenhall arriving from Los Angeles and believed her behavior matched drug-courier characteristics.
- Agents approached in the concourse, identified themselves, and asked to see her airline ticket and identification.
- Mendenhall produced a driver’s license in her name and a ticket issued in another name; the agents questioned her briefly about the discrepancy and her travel.
- The agents returned her ticket and license and asked if she would accompany them to the DEA office; she agreed and went with them.
- In the DEA office, an agent asked for consent to search her person and handbag and informed her she could refuse; Mendenhall said “Go ahead” and handed over her purse.
- A female officer again asked for consent to a personal search; Mendenhall again indicated consent.
- When told the search would require removal of clothing, Mendenhall said she had a plane to catch; she was told that if she had no narcotics there would be no problem.
- Mendenhall began to disrobe, removed two packages from her undergarments (one appearing to contain heroin), handed them to the officer, and was then arrested.
- The district court denied a suppression motion and Mendenhall was convicted; the Sixth Circuit reversed for lack of valid consent.
Issues
- Whether Mendenhall was “seized” under the Fourth Amendment before she produced the heroin.
- Whether her consent to accompany agents and to be searched was voluntary under the Fourth Amendment.
Decision
- The Supreme Court reversed the Sixth Circuit and remanded.
- A plurality concluded Mendenhall was not seized when agents approached, requested identification and a ticket, asked questions, and requested that she accompany them to the DEA office.
- The Court upheld the trial court’s finding that Mendenhall voluntarily consented to accompany the agents and to the search, making the heroin admissible.
- The rationale was divided among Justices; the judgment rested on a plurality opinion with concurring views emphasizing the consensual nature of the encounter and, alternatively, reasonable suspicion.
Legal Principles
- A person is seized under the Fourth Amendment only if, considering all circumstances, a reasonable person would believe they were not free to leave.
- Not every interaction between police and a citizen constitutes a seizure; officers may ask questions and request identification without automatically triggering Fourth Amendment seizure rules.
- Circumstances suggesting a seizure include the threatening presence of multiple officers, display of weapons, physical touching, or language or tone indicating compliance is compelled.
- Voluntariness of consent to search is determined from the totality of the circumstances; an advisement of the right to refuse consent is an important indicator of voluntariness but not an absolute prerequisite.
- Appellate courts should not substitute their view of the evidence for a trial court’s supported factual finding on voluntariness in suppression rulings.
Conclusion
The Court held that the airport encounter did not amount to a Fourth Amendment seizure before Mendenhall consented, and that her consent to accompany agents and submit to a search was voluntary under the totality of the circumstances, so the seized heroin was admissible.
