Trimble v. District of Columbia, 779 F. Supp. 2d 54

Trimble sues DC, MPD Chief Lanier, other officials, unnamed officers, and Mays under 42 U.S.C. § 1983, plus state-law claims arising from MPD’s response to a fatal domestic-violence incident.
Decedents Erika Peters, Erik Harper, and Dakota Peters were killed during an incident involving Joseph R. Mays; MPD delayed forcing entry after a 911 call.
Plaintiff asserts MPD policies, practices, and customs discriminating against domestic-violence victims, leading to less aggressive response to domestic assaults.
Plaintiff also challenges DC Child and Family Services Agency policies, alleging related failures in child abuse matters.
District defendants move to dismiss for failure to plead a municipal policy/custom under Monell and related grounds; official-capacity claims against certain officials are duplicative.
Court grants motion to dismiss the § 1983 claim for failure to plead a cognizable municipal custom or policy and declines supplemental jurisdiction over remaining DC claims, dismissing them.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Trimble pleads a Monell policy or custom	Trimble asserts MPD has policies/customs that discriminate against domestic violence victims, causing harm.	District contends plaintiff fails to identify a specific policy or widespread custom causing the harm.	§ 1983 claim dismissed for lack of pleaded policy/custom
Whether remaining DC statutory/common law claims should be heard in federal court	Supplemental jurisdiction appropriate for related DC claims.	With § 1983 claim dismissal, no basis for federal exclusive jurisdiction over these claims.	Supplemental jurisdiction declined; remaining claims dismissed
