310 F. Supp. 3d 1066
S.D. Cal.2018Background
- On Jan 8–9, 2016 the San Diego Regional Fugitive Task Force (FTF) executed a search of Trina Koistra’s mobile home seeking Rory Fay, a wanted, two‑strike, potentially armed homicide suspect; multiple loud PA warnings about a canine were made before entry.
- Deputy Plutarco Vail deployed his police canine (Hank) into a bedroom closet where Koistra was hiding; Hank bit and dragged Koistra, inflicting severe facial and jaw injuries.
- Koistra contends she surrendered (raised hands, said she was unarmed) before the canine continued biting for about 30 seconds; Defendants say the canine contacted her briefly while searching for Fay and was released once Fay was later found under a bed.
- Koistra pleaded guilty to violating probation arising from the incident; Fay was later convicted of murder.
- Procedurally, Defendants moved for summary judgment as to Koistra’s §1983 excessive‑force claim, Monell claim, state‑law causes (Bane Act §52.1, battery, assault, IIED, negligence), false arrest, and punitive damages.
- The Court granted summary judgment as to the initial deployment of the canine (reasonable) but denied summary judgment on the continued/prolonged bite after alleged surrender; Monell and false‑arrest claims were dismissed as to the County; qualified immunity was denied for the prolonged bite theory; certain state claims survive as to the prolonged conduct.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Excessive force (initial canine deployment) | Canine deployment was unreasonable | Deployment was reasonable given dangerous suspect and warnings | Deployment reasonable; summary judgment granted for Defendants |
| Excessive force (continued bite after surrender) | Vail unreasonably allowed canine to continue biting after Koistra surrendered | Bite was brief/necessary; no constitutional violation | Triable issue exists; summary judgment denied on continued bite |
| Qualified immunity (continued bite) | Existing precedent put officer on notice prolonged canine bite after surrender is unlawful | Officer not on notice of clearly established law | Denied as to prolonged bite — right was clearly established |
| Monell (County policy) | County has "bite‑and‑hold" policy that causes constitutional violations | No express policy shown; canine use broadly lawful | Monell claim dismissed — plaintiff failed to show policy was the moving force |
