State v. Jimenez, 420 P.3d 464

Background

Officer Blake stopped Jimenez's rented Mustang for following too closely; both occupants had limited English and the officer used hand gestures and a translation app.
Blake observed bundled cash in the glove box and asked Jimenez to sit in his patrol car; he admitted he intended only a warning citation.
While in the patrol car, Blake spent about 4½ minutes asking detailed travel-plan questions (origin, destination, purpose, where they slept) before running license and warrant checks.
After dispatch checks began, Blake deployed a certified police dog; the dog alerted and officers searched the car, finding about $50,000 in cash; Jimenez was charged with offenses related to drug proceeds.
The district court suppressed the evidence, concluding the travel-plan questioning measurably extended the stop without reasonable suspicion or consent; the Court of Appeals reversed, prompting Supreme Court review.

Issues

Issue	Plaintiff's Argument (State)	Defendant's Argument (Jimenez)	Held
Whether travel-plan questions are always within a traffic stop's mission	Travel-plan questions are routine and always permissible during a stop	Travel-plan questioning can be unrelated and may unlawfully extend a stop	Not always permissible; circumstances control — travel questions must relate closely to roadway safety or occur concurrently with mission tasks
Whether Blake measurably extended the stop by asking travel-plan questions before processing license/warrants	The total short duration (under 7 minutes) was reasonable; travel questions do not count against stop duration	The 4½ minutes of travel questioning delayed mission tasks and unlawfully prolonged the detention	The questioning delayed mission tasks and thus measurably extended the stop without justification
Whether officers had reasonable suspicion or probable cause to extend the stop	Officer had observations (rental, cash) and answers that could justify follow-up	Officer admitted he had no suspicion; the cash was a mere observation and questions were not based on suspicion	No reasonable suspicion or probable cause existed to justify the extension
Whether suppression of evidence was required as fruit of unconstitutional detention	Evidence lawfully obtained after a lawful stop and canine alert	Evidence was the product of an unconstitutional extension and must be suppressed	Suppression affirmed; district court correctly excluded evidence and Court of Appeals reversed
