The Checkpoint, the Cooler, and the Confession
At 11:40 p.m. on July 4, CNMI police operate a sobriety checkpoint on Beach Road, stopping every third car. Officer Reyes stops Maria's car because it is the third vehicle. She smells of alcohol and fails a field sobriety test. While Maria is outside, Reyes shines a flashlight into the car and sees a closed, opaque cooler on the back seat. He asks, 'Anything in the cooler?' Maria says, 'Just soda.' Without asking permission, Reyes opens the cooler and finds a small bag of methamphetamine. Maria is arrested. At the station, after receiving Miranda warnings, she says, 'I only sell a little to friends.' Before trial, Maria moves to suppress the methamphetamine and her statement. The government argues the checkpoint was valid, the cooler search was lawful under the automobile exception, and the statement was voluntary.
1. Was the sobriety checkpoint and Maria's stop lawful under the Fourth Amendment and the CNMI Constitution?
Read the worked answer
A sobriety checkpoint can be reasonable without individualized suspicion if it is conducted under a neutral, published plan, with limited officer discretion, at a reasonable location and time, and with minimal intrusion. Stopping every third car is neutral on its face. The 11:40 p.m. timing and Beach Road location support a traffic-safety purpose. However, the record must show supervisory approval and consistent operation; if officers deviated or used the checkpoint as a pretext, the stop could be invalid. Maria's smell of alcohol and failed field sobriety test independently supply reasonable suspicion for the investigation. On these facts, the checkpoint and stop are likely lawful.
2. Was the warrantless search of the closed cooler lawful?
Read the worked answer
No. The automobile exception allows a warrantless search of a vehicle only when there is probable cause to believe contraband or evidence is inside. A closed, opaque cooler is a container; the officer had no probable cause before opening it. Maria's statement 'just soda' is not consent; it is an answer to a question, and the officer did not ask permission. The flashlight observation of the cooler does not reveal its contents. The government cannot rely on the automobile exception because the smell of alcohol and failed sobriety test suggest intoxication, not drugs in the cooler. The search violated the Fourth Amendment and the CNMI Constitution, so the methamphetamine should be suppressed.
3. Should Maria's stationhouse statement be suppressed?
Read the worked answer
Likely yes, unless the government proves attenuation. The statement came after Miranda warnings, so it was not compelled by custodial interrogation. But it was obtained after an illegal search and arrest. Under the fruit-of-the-poisonous-tree doctrine, a voluntary statement can still be suppressed if it was tainted by the prior illegality. The government would need to show that the statement was an independent act, that significant time passed, or that the illegality was not the but-for cause. On these facts, the statement 'I only sell a little to friends' came at the station soon after the search and was prompted by the discovery. The court should suppress the statement as fruit unless the government develops attenuation evidence. Miranda warnings alone do not cure the taint.
