The 25-Minute Stop and the K-9
At 1435, Officer Lane stops a rented compact car on Interstate 25 for a registration expired six days earlier. The driver, 28, is from Colorado and says he is returning from a funeral. The passenger stares straight ahead and answers only yes or no. Lane notices two cell phones on the console, fast-food wrappers, a heavy air-freshener smell, and a rental agreement listing a different authorized driver. The driver says the renter is his cousin who gave permission by text, but the text is not in his phone. Lane calls for a K-9 at minute 4. Dispatch says the dog is 10 minutes out. Lane finishes the written warning at minute 12 but keeps the driver beside the car, saying, 'We're waiting on a dog.' The K-9 arrives at minute 22 and alerts at minute 25. Officers find 18 grams of methamphetamine in the center console. Lane's report says the driver was 'extremely nervous' and the car smelled of 'masking agents.'
1. Identify the moment the seizure likely became unlawful and explain why under Fourth Amendment and New Mexico law.
Read the worked answer
The stop likely became unlawful at minute 12, when Lane completed the warning and had no further traffic mission to perform. A dog sniff is not itself a search under Illinois v. Caballes, but the Fourth Amendment and Article II, Section 10 of the New Mexico Constitution prohibit prolonging a stop beyond the time reasonably needed to complete its mission. Waiting for a K-9 is not an ordinary part of a traffic stop. Once the warning was written and the license, registration, and warrant checks were done, Lane needed reasonable suspicion of criminal activity to keep the driver. Saying 'we're waiting on a dog' is evidence of prolongation.
2. Evaluate whether the facts known to Lane supplied reasonable suspicion to extend the stop. Which facts carry weight and which do not?
Read the worked answer
Some facts can support reasonable suspicion, but the report overstates them. The rental agreement not listing the driver as authorized is significant, especially when the driver's explanation is an unverified text from a cousin. Inconsistent or evasive answers about the rental can also count. But nervousness, two cell phones, fast-food wrappers, and air freshener are weak or innocent; 'masking agents' is a conclusion, not an observation. The passenger's silence adds little. The totality may support a brief inquiry into the rental authorization, but if the cousin's permission cannot be verified, that does not automatically equal reasonable suspicion of drug trafficking. Lane should articulate specific facts, not a profile.
3. What should Lane have done to preserve the stop's legality, and what is the likely remedy if the extension was unlawful?
Read the worked answer
Lane should have completed the citation and either released the driver or asked for consent to search, clearly documenting that the driver was free to go. If he wanted a dog, he should have called earlier and kept the stop within its mission, or developed independent reasonable suspicion. The report should separate observations from conclusions. If the extension was unlawful, the meth is fruit of the poisonous tree and likely suppressed, along with statements. The state might argue the dog alert was independent, but that fails if the alert came during an unlawful prolongation.
