Kristy Cunningham appeals after the district court 1 adversely granted judgment on the pleadings, under Federal Rule of Civil Procedure 12(c), in her 42 U.S.C. § 1983 action. Upon de novo review, see Montin v. Moore, 846 F.3d 289, 293 (8th Cir. 2017) (reviewing de novo a grant of a Rule 12(c) motion), we conclude that the district court properly determined that Cunningham’s claims for damages were barred under Heck v. Humphrey, 512 U.S. 477, 486-87, 114 S.Ct. 2364, 129 L.Ed.2d 383 (1994) (stating that if a judgment in favor of the plaintiff would necessarily imply the invalidity of a conviction or sentence, the complaint must be dismissed unless the plaintiff can demonstrate that the conviction or sentence has already been invalidated). Accordingly, we affirm. See 8th Cir. R. 47B.
