Gaines v. Moore City of, 5:20-cv-00851

On December 14, 2019, off-duty Moore police officer Kyle Lloyd fatally collided with Emily Gaines while speeding to deliver spare keys to a fellow officer for a community event.
Plaintiffs, the Gaines family, sued the City of Moore and its police officials, alleging municipal liability under 42 U.S.C. § 1983 and state-law liability under the Oklahoma Governmental Tort Claims Act (GTCA).
The federal district court previously dismissed most claims, leaving alive only the § 1983 claim based on the City’s failure to supervise Lloyd and the GTCA state-law claim.
Lloyd had past minor driving incidents as a police officer and was previously involved in a high-speed off-duty traffic stop, but there was little documentation of serious discipline or reporting up the chain.
The City had a lax disciplinary matrix and allowed officers to request removal of old disciplinary records, though there was little evidence these policies were misapplied in practice.

Issue	Plaintiff's Argument	Defendant's Argument	Held
§ 1983 Municipal Liability – Failure to Supervise	City ignored Lloyd's history of unsafe driving and poor discipline, making later constitutional harm to citizens highly predictable	Lloyd’s history did not make harm highly predictable; no serious or repeated misconduct, and City decision-makers not on notice	For City: No deliberate indifference or causation shown; summary judgment granted
§ 1983 Municipal Liability – Causation	City’s lack of proper supervision/training was the moving force behind Gaines’s death	Lloyd's own irrational, off-duty actions were the direct cause, not City policy/practice	For City: No evidence City actions were moving force; summary judgment granted
GTCA State-Law Liability – Scope of Employment	Lloyd was acting within scope, responding to an official request for the benefit of police duties	Lloyd acted outside scope via willful/wanton, unlawful conduct, so City immune	For Plaintiff: Whether Lloyd acted within scope is a factual issue for jury; summary judgment denied
Disciplinary Matrix and Record Purge Policy	Overly permissive matrix and record purge practice enabled dangerous officers to persist	No evidence these policies led to actual discipline failures relevant to this case	For City: Policies did not show deliberate indifference or a predictable harm
