Defendant appeals the denial of his motion to suppress the warrantless seizure of a small amount of marijuana from his vehicle. A police officer seized the marijuana after stopping defendant's vehicle for an equipment violation. During the stop, the officer smelled the odor of marijuana coming from inside the car while questioning defendant through the open passenger side window.The State contends the officer's slight intrusion inside the vehicle's window, for the sole purpose of better hearing defendant over the noise of passing traffic, did not constitute a search. Defendant argues it was a search, and that it was unlawful because the officer was not legally in the "smelling area" when he detected the odor of marijuana and developed the probable cause to seize it. Assuming without deciding that the officer conducted a search when he leaned his head inside defendant's open window, the panel concludes that the officer's slight, momentary intrusion inside the car window to hear defendant's responses was reasonable. Consequently, the search did not violate the Constitutional protection against "unreasonable searches and seizures." The marijuana was then properly seized pursuant to the "plain smell" exception to the warrant requirement. The trial court order denying the suppression motion is affirmed.
