Ellison v. United States, 238 A.3d 944

Officer Hinton observed what he believed was a hand-to-hand drug sale: a man (later identified as Rashad Ellison) reached into his front waistband, exchanged a small item for cash, and rode a bicycle; Hinton radioed descriptive information to the surveillance team.
Officer Stout tailed the buyer, directed other officers to stop the seller, and later recovered a small bag of crack on the buyer after stopping and searching him.
Officers Rubin and Nunez detained Ellison, Rubin handcuffed and frisked him (found only money), then—after the buyer’s recovery—Rubin conducted an intrusive on-scene search of Ellison’s shorts/underwear (found no drugs).
Ellison was then arrested, taken to the station, strip-searched, and forty-six small bags of crack were found.
Ellison moved to suppress the drugs as Fourth Amendment fruit of an unlawful seizure/search; the trial court denied suppression, he pleaded guilty reserving appeal; the appellate court affirmed.

Issue	Ellison's Argument	Government's Argument	Held
1) Was there probable cause to arrest/search Ellison?	The observed hand-to-hand transaction alone did not establish probable cause; no evidence Officer Rubin knew buyer had crack before searching Ellison.	Recovery of crack from the buyer plus observation of the hand-to-hand sale supplied probable cause; collective-knowledge doctrine imputes buyer recovery to officers who acted.	Yes. Probable cause accrued once officers recovered crack from the buyer and that fact can be imputed under the collective-knowledge doctrine; arrest/search were supported.
2) Was pre-arrest detention unconstitutionally prolonged under Terry?	The detention exceeded the brief investigatory window and became an unlawful arrest because officers detained Ellison over ten minutes before formal arrest and conducted an intrusive search on-scene.	The Terry stop lasted only ~3 minutes before probable cause accrued (then arrest justified); the brief pre-probable-cause detention was reasonable and officers diligently pursued investigation.	No. The court treated only the ~3 minutes before probable cause as the Terry detention, found that brief detention reasonable, and concluded the longer post-probable-cause restraint was justified by arrest.
