State v. Croff, 2017 Ohio 8629

Vincent Croff was prosecuted for possession of cocaine (fifth-degree felony) after a traffic stop in a high-crime area; a police K-9 handler (Officer Edwards) initiated the stop for an alleged roll-through of a stop sign.
During the stop Edwards asked to search the vehicle; Croff refused, was asked to exit, a pat-down began, and Croff fled on foot; officers later recovered a baggie of crack cocaine in the area Croff fled.
Croff was tried three times: the first two jury trials ended in mistrials (hung juries); the third trial resulted in conviction.
Croff moved to dismiss for speedy-trial violation (delay between second mistrial and third trial), to suppress statements and evidence as fruit of an unconstitutional stop/search, and sought admission of roughly 100 K-9 use reports; he also challenged the weight of the evidence.
The trial court denied suppression and excluded the K-9 reports; the jury convicted Croff and the court of appeals affirmed.

Issue	Plaintiff's Argument (State)	Defendant's Argument (Croff)	Held
1. Speedy trial after two mistrials	Delay (~102 days) was reasonable; Barker factors apply to retrials and did not require dismissal	Delay between 2nd mistrial and 3rd trial was unreasonable and violated speedy-trial rights	Affirmed: 102-day delay not presumptively prejudicial; no further Barker inquiry required
2. Suppression of statements, flight, and narcotics	Stop was supported by probable cause; removal and pat-down permissible (Mimms); dog sniff not conducted before flight	Stop was pretextual (video shows a stop) and was unlawfully prolonged to conduct a dog sniff; evidence should be suppressed	Affirmed: stop was lawful; officer credibility credited; removal lawful and pat-down not challenged; no suppression required
3. Admissibility of Officer Edwards’ K-9 reports	Exclusion proper: reports lacked relevance or probative value and would invite speculation; extrinsic evidence barred under Evid. R. 608(B)	Reports show pattern (race-based targeting) and impeach Edwards’ truthfulness	Affirmed: trial court did not abuse discretion excluding reports as not clearly probative and prejudicial/speculative
4. Manifest weight of the evidence	Jury reasonably credited officer testimony; cocaine found in Croff’s flight path supports possession	Conviction against manifest weight; alternative explanations (other pedestrian) possible	Affirmed: conviction not against manifest weight; jury did not lose its way
