Drug-detection dog’s alert supports bus luggage search

Listen to this article

The 4th U.S. Circuit Court of Appeals held that a trained drug-detection dog’s alert provided probable cause to search suitcases on a commercial bus under the automobile exception to the Fourth Amendment.

Law enforcement officers stopped a commercial bus traveling from Atlanta to New York after observing traffic violations. With the driver’s consent, officers opened the bus’s luggage compartment. A trained narcotics-detection dog alerted to the luggage area. Officers then searched a suitcase and discovered approximately 10 kilograms of cocaine. A second suitcase later yielded another 10 kilograms. The defendant was convicted of cocaine trafficking offenses and moved to suppress the evidence.

The court first addressed standing. The defendant retained a privacy interest in the first suitcase because officers searched it before he denied owning any luggage. However, the defendant abandoned any expectation of privacy in the second suitcase by repeatedly disclaiming ownership before that bag was searched, eliminating his ability to challenge that search.

Even with standing as to the first suitcase, the search was lawful. The court held that the automobile exception applied to the commercial bus and containers within it. Because vehicles are readily mobile and carry reduced expectations of privacy, officers may conduct a warrantless search if they have probable cause to believe the vehicle contains contraband.

The court concluded that the dog’s alert provided probable cause. The district court credited testimony from the handler that the dog alerted through behavioral changes rather than its typical final signal, and the dog had been repeatedly certified by a recognized narcotics-detection organization with a strong reliability record. Considering the totality of the circumstances, the court held that the warrantless search was justified.
