State v. Thomas, 2020 Ohio 3539

On Nov. 23, 2018 Detective Heim (drug task force) observed Chelsea Thomas stop at an apartment under suspected drug surveillance; he followed and radioed Officer Brian Haddix, who stopped Thomas for a marked lanes violation.
Haddix contacted Thomas, took her license and began checking her information by mobile data terminal and told her he intended to issue a warning if everything checked out.
Haddix radioed dispatch to request a K‑9 from Cuyahoga Falls while he began preparing the written warning; Officer Barker arrived as backup during this process.
After Barker arrived Haddix paused writing the warning, conversed with Barker (including unrelated topics), and searched for a female officer on his MDT; about three minutes later the K‑9 unit arrived.
The K‑9 handler asked Thomas to exit and whether there was any reason the dog would alert; Thomas then admitted there were psilocybin mushrooms under the front passenger seat and officers searched the car.
The trial court suppressed Thomas’s statements and the evidence, concluding the traffic stop was unreasonably extended to await the K‑9 and there was no reasonable suspicion to prolong the stop; the court of appeals affirmed (one judge dissented).

Issue	Plaintiff's Argument (State)	Defendant's Argument (Thomas)	Held
Whether Haddix impermissibly extended the traffic stop to await a K‑9 sniff	Haddix acted diligently and completed routine tasks within a reasonable time; any short pauses were reasonable and did not impermissibly prolong the stop	Haddix paused unrelated tasks and delayed completing the warning to wait for the K‑9, extending the seizure beyond the time needed to issue a warning	Stop was impermissibly extended; trial court’s factual findings that Haddix paused for unrelated conversation and MDT searches are supported by bodycam evidence and credible testimony; extension was unreasonable
Whether officers had reasonable suspicion to lawfully prolong the stop for further investigation/K‑9 sniff	Knowledge that Thomas had been at a location under drug surveillance and her nervousness supported reasonable suspicion to detain longer	No additional specific, articulable facts arose during the stop to justify prolongation; nervousness and an incomplete travel explanation did not supply reasonable suspicion	No reasonable suspicion existed to prolong the stop; omission about a prior stop and slightly nervous demeanor did not reasonably justify extending the seizure
