People v. Abdur-Rahim, 16 N.E.3d 903

Trooper Morscheiser stopped Abdullah Abdur‑Rahim on I‑80 for following too closely and crossing a yellow line; he wrote warning tickets and ran a computer check of defendant’s license.
During the initial approach Morscheiser believed he faintly smelled cannabis but expressed uncertainty on the video; dispatch later reported defendant appeared on a terrorist watch list.
The troopers delayed completing the stop while verifying watch‑list identity (about 23–30 minutes); after tickets were completed and watch‑list status resolved, they kept defendant detained an additional ~22 minutes.
Trooper Patterson reported smelling a masking agent (e.g., strong deodorant) but did not testify he smelled cannabis or that the masking agent indicated contraband.
Morscheiser asked defendant to exit, questioned him, and defendant admitted a small smoking device in the truck; a canine was summoned, alerted at the tailgate, and troopers discovered multiple duffel bags containing 5,505 grams of cannabis.
The trial court denied motions to suppress (evidence and statements); a jury convicted Abdur‑Rahim and he was sentenced to seven years. The appellate court reversed, holding the post‑ticket detention lacked reasonable suspicion and the evidence should have been suppressed.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether officers lawfully prolonged a traffic stop to investigate drugs after tickets and watch‑list check were completed	The faint odor of burnt cannabis (plus Patterson’s masking‑agent observation) gave reasonable articulable suspicion to extend the stop and seek a canine	The stop was unreasonably prolonged after the warnings and watch‑list check resolved; the troopers only had a mere suspicion or uncertainty about marijuana	Court: Stop unlawfully extended; officer’s uncertain smell and masking‑agent remark did not supply reasonable suspicion — suppression of evidence required
Whether defendant’s statements to officers should be suppressed (Miranda/custody)	Statements were voluntary and not custodial because defendant was not under arrest during the questioning	Statements occurred during an extended, coercive detention and suppression was appropriate	Court: Ruling on statements rendered moot by suppression of physical evidence; conviction reversed outright
