State v. Brooks, 2016 Ohio 7025

Early morning traffic stop of a tan Chevy Impala after officer observed one inoperable headlight and an alleged lane crossing; plate check showed vehicle registered to Anthony Brooks.
Officer Holzapfel had K-9 Diesel in cruiser and prior information from the county drug unit that Brooks might be involved in drug activity.
During the stop officer observed numerous air fresheners in the vehicle; Brooks remained evasive and stared forward, and handed over license.
Officer began completing citation and ran court checks on cruiser computer; backup arrived while citation still in progress.
Officer asked Brooks to exit, obtained consent to search his person (negative), then deployed K-9; Diesel alerted at rear driver-side door and officer searched vehicle discovering a firearm and marijuana.
Brooks was indicted on weapons, stolen property, and marijuana counts; he moved to suppress, plea-bargained to two felonies, appealed denial of suppression; appellate court affirmed.

Issue	Brooks' Argument	State's Argument	Held
Lawfulness of initial traffic stop	Stop based solely on disputed lane change; lacked reasonable suspicion	Stop was premised on both lane crossing and inoperable headlight; headlight violation undisputed	Stop lawful because inoperable headlight provided basis for stop
Legality of K-9 sniff without probable cause	Officer lacked probable cause to have dog sniff vehicle	K-9 sniff is not a Fourth Amendment "search" and needs no suspicion when conducted during lawful stop	K-9 sniff permissible under Caballes; no probable cause required before sniff
Whether the dog sniff and actions unreasonably prolonged the stop	Sniff and subsequent search impermissibly extended stop beyond mission of traffic stop	Observations (air fresheners, prior drug information, evasive behavior) gave reasonable suspicion to briefly extend stop for sniff; officer acted diligently	No unconstitutional prolongation: facts provided reasonable suspicion and sniff occurred within minutes
Warrantless search of vehicle following dog alert	Warrantless search unsupported by probable cause and consent	A trained dog’s alert provides probable cause to search vehicle for contraband	Dog’s alert gave probable cause; warrantless search was lawful
