977 F.3d 483
6th Cir.2020Background:
- On Nov. 9, 2013, Pineda was struck on the back of the head outside a Cincinnati nightclub while three off-duty sheriff’s deputies (two Black, one white) were providing uniformed security in the parking lot.
- Pineda suffered significant head injury and memory loss; he testified the attacker was a Black deputy but never identified which deputy struck him.
- The three deputies denied using force or seeing the assault; internal affairs opened a limited investigation but could not locate Pineda and left the case open.
- Pineda sued the three deputies under 42 U.S.C. § 1983 for excessive force and sued the Hamilton County Sheriff’s Office and Sheriff Neil for ratifying the alleged misconduct by failing to investigate adequately.
- The district court granted summary judgment for all defendants; the Sixth Circuit reviewed de novo and accepted Pineda’s factual account for purposes of the motion.
Issues:
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Excessive-force liability of all three deputies when only one allegedly struck Pineda | Pineda argues he should proceed to trial against all three because he testified a deputy struck him but could not identify which one | Defendants argue § 1983 requires personal involvement and plaintiff must show which officer, and summary judgment is proper when evidence is in equipoise | Court held plaintiff failed to produce evidence that it was more likely than not any specific deputy committed the constitutional violation; summary judgment affirmed for all three deputies |
| Municipal liability / ratification by Sheriff’s Office and Sheriff Neil based on alleged inadequate investigation | Pineda contends the cursory internal affairs probe and post hoc approval amount to ratification and municipal policy causing injury | Defendants argue Monell requires a municipal policy or pattern and that a single after‑the‑fact inadequate investigation cannot cause the prior injury | Court held plaintiff produced no evidence of a pattern or causation from the single investigation; ratification claim failed and summary judgment affirmed |
