Abilio Hernandez v. Jason Boles, 949 F.3d 251

Background

Troopers stopped Hernandez for speeding; four occupants were in the SUV (driver Hernandez, owner/front passenger Betancourt, and two rear passengers). Trooper intended to issue a warning unless indicators of crime appeared.
Officers ran NCIC warrant checks; initial NCIC checks for Hernandez and Betancourt came back negative within minutes; NCIC checks for the rear passengers were also negative shortly thereafter.
Trooper Clark called a more comprehensive database (BLOC) about 20 minutes into the stop while a K‑9 unit was requested and en route.
K‑9 alerted to the exterior of the SUV but did not alert after being allowed inside (handler testified the dog ‘‘didn’t hit’’ and spent time eating fast food inside the vehicle). Officers then obtained supervisory authorization and conducted a manual search, finding hundreds of re‑encoded gift cards and suspected meth; occupants were arrested and held pretrial for months; charges were later dismissed.
Plaintiffs sued under 42 U.S.C. § 1983 alleging (1) an unlawful search and (2) an unreasonable prolongation of the traffic stop. The district court granted qualified immunity on the search claim and a jury found the stop was not impermissibly prolonged; the district court denied plaintiffs’ Rule 50 JMOL. The Sixth Circuit AFFIRMED.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether the traffic stop was impermissibly prolonged (Rodriguez)	Running a second database check (BLOC) and waiting ~20 minutes unreasonably extended the stop	Warrant checks and questioning were ordinary inquiries; dog arrived while awaiting BLOC, so stop was not prolonged	Jury found no unlawful prolongation; appellate court affirmed denial of Rule 50 because reasonable minds could differ and the issue was factbound
Whether manual search after a K‑9 exterior alert but no interior alert violated the Fourth Amendment	Dog’s failure to alert inside dissipated probable cause; subsequent manual search was illegal	Exterior alert gave probable cause to search; officers reasonable to rely on alert; qualified immunity applies	There was a factual dispute about whether the interior sniff was sufficiently thorough to dissipate probable cause; but law was not clearly established that the interior non‑alert nullified an earlier exterior alert — qualified immunity affirmed
Whether a drug dog’s failed interior alert necessarily dispels probable cause	Plaintiffs: Davis and Bowling support that a fruitless/failure search can dissipate probable cause	Troopers: no controlling precedent holding that a subsequent non‑alert defeats an earlier exterior alert in these circumstances	Circuit precedent allows a reasonable jury to find the non‑alert dissipated probable cause, but precedent was not specific enough to give officers fair warning here
Whether pretrial incarceration damages are recoverable for an illegal search/seizure	Plaintiffs sought damages for months detained pretrial	Troopers contested liability	Court did not decide because there is no liability in this case (issue pretermitted)
