Tony Day appeals after the District Court 1 granted the defendants’ motions for judgment on the pleadings in Day’s 42 U.S.C. § 1983 action related to medical care he received at a county jail. After de novo review, we conclude that the motions were properly granted. See Greenman v. Jessen, 787 F.3d 882, 887 (8th Cir. 2015) (standard of review); see also Bd. of the Cty. Comm’rs v. Brown, 520 U.S. 397, 403-04, 117 S.Ct. 1382, 137 L.Ed.2d 626 (1997) (discussing municipal liability under § 1983); Owens v. Scott Cty. Jail, 328 F.3d 1026, 1027 (8th Cir. 2003) (per curiam) (noting that “county jails are not legal entities amenable to suit”); Smith v. Insley’s Inc., 499 F.3d 875, 880 (8th Cir. 2007) (discussing liability of corporations under § 1983). We affirm the judgment.
