United States v. Leonel Aguilera - Pena, 426 F. App'x 368

Pena was stopped for improper lane use by a Michigan officer acting on federal agents’ surveillance for suspected narcotics trafficking.
During the stop, Pena was asked about contraband and large sums of cash; Pena answered no and began avoiding eye contact, prompting a search consent.
Corporal Smith patted Pena down, searched the vehicle interior and trunk, and handed Pena to Federal Agent McCanna as the stop continued.
Within minutes, Pena admitted he had been paid $5,000 to drive the car from Oregon to Detroit, giving McCanna probable cause to believe contraband was present.
The car was transported to a nearby garage for a more thorough search; a dog alerted to the car, revealing a hidden compartment with $410,000, heroin, and a handgun.
Pena was charged with possession with intent to distribute heroin and moved to suppress the seized evidence; the district court denied the motion, and Pena appealed.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Did extraneous questions prolong the stop unlawfully?	Pena argues the questions exceeded the stop’s scope and duration.	Smith/McCanna contend questions were brief and did not prolong the stop.	No; questions were permissible and did not extend the stop.
Was the consent to search valid within the traffic-stop context?	Pena challenges the validity of the consent given under stop conditions.	Consent was voluntary and appropriate after the initial stop.	Yes; consent valid and permissible.
Did Pena’s statements create probable cause to further detain beyond the initial stop?	Claims no further detention was justified beyond the traffic stop.	Pena’s statements about drug trafficking created probable cause to detain for a longer search.	Pena’s statements provided probable cause to further detain; detention reasonable.
Was the expanded detention and search permissible under Fourth Amendment framework (Burton/Robinette/ Everett)?	Argues the extended detention and search were unlawful.	The conduct fell within established Fourth Amendment tolerances for detentions during a lawful stop.	Yes; detainment and search were reasonable under controlling precedents.
