JAMES DICKSON PHILLIPS, Circuit Judge:
Rhonda R. Milligan appeals from the district court’s dismissal of her action under 42 U.S.C. § 1983 seeking damages for personal injuries allegedly caused by the negligent conduct of employees of the defendant-municipality that was traceable to the municipality’s failure adequately to train them. The court dismissed for lack of subject matter jurisdiction or, alternatively, for failure to state a cognizable claim. We affirm the dismissal on the merits.
I
The critical allegations of Milligan’s complaint, accepted as true for purposes of this appeal, are as follows. On December 31, 1982, Milligan sustained serious injuries to her spinal cord when the vehicle in which she was a passenger left the road and crashed. Within minutes after the accident, emergency medical technicians (EMTs) and police officers, all employees of the City of Newport News (City), the defendant-appellee in this case, arrived at the scene and “assumed care and control” of Milligan. These officers negligently failed to recognize Milligan’s state of delirium and her urgent need for prompt medical attention and instead of performing routine tests that would have disclosed that need, caused Milligan to sign a refusal of medical care form and called a cab to take her home. When the cab arrived, the officers placed Milligan into the cab, causing further injury to her spine.
When the cab arrived at Milligan’s residence, she alleges, the cab driver told her to go inside. When Milligan responded that she could not move her legs, the driver summoned Newport News police officers who upon arrival pulled Milligan from the cab, “dragged her into the house, and flopped her down on the couch in her living room.” Each of these acts negligently performed by City personnel, and all of them in combination, exacerbated Milligan’s earlier-incurred spinal injury, ultimately bringing about her present quadraplegic condition.
Milligan brought suit against the City alleging that her injuries were the proximate result of the City’s negligent or grossly negligent failure adequately to train and supervise its emergency personnel in the “diagnosis, handling, and treatment of automobile accident victims.” This failure, she alleges, constituted “reckless and callous indifference to the plaintiff’s federally protected rights” and deprived her of “liberty ... without due process of law” in violation of 42 U.S.C. § 1983.
The district court dismissed Milligan’s action because of the absence of a vital allegation: that the City’s emergency personnel deprived Milligan of constitutionally protected rights pursuant to an “official policy, practice, or custom” of the City. Thus, the court held, under principles enunciated in Monell v. Department of Social Services, 436 U.S. 658, 98 S.Ct. 2018, 56 L.Ed.2d 611 (1978), that the City could not be held liable for the allegedly unconstitutional acts of its employees which gave rise to Milligan’s injuries. This appeal followed. ■

Before considering the legal sufficiency of Milligan’s complaint, we state briefly the controlling principles of law.
First, municipal liability under § 1983 may not be predicated solely upon a respondeat superior theory. Liability arises only where the constitutionally offensive acts of city employees are taken in furtherance of some municipal “policy or custom.” Monell, 436 U.S. at 694, 98 S.Ct. at 2037.
Such a policy or custom may be found in edicts of the city's formal decision-making body or in “persistent ... practices of [municipal] officials” having the de facto force of law. Adickes v. S.H. Kress & Co., 398 U.S. 144, 167-68, 90 S.Ct. 1598, 1613-1614, 26 L.Ed.2d 142 (1970); Languirand v. Hayden, 717 F.2d 220, 222 (5th Cir.1983). In addition, such a policy or custom may possibly be inferred from continued inaction in the face of a known history of
