PER CURIAM.

      Charles Alexander/Ryahim (Ryahim) appeals the district court’s1 preservice
dismissal of his 42 U.S.C. § 1983 complaint. Ryahim also filed a motion requesting
our panel review a videotape of his jury trial in another civil case.

       Upon de novo review, see Moore v. Sims, 

, 1171 (8th Cir. 2000)
(per curiam) (explaining that an appellate court reviews de novo a dismissal for failure
to state a claim under 28 U.S.C. § 1915(e)(2)(B)), we conclude dismissal was proper
because a judgment in Ryahim’s favor on his conspiracy claim would imply the
invalidity of his conviction, and Ryahim did not allege his conviction had been
overturned. See Heck v. Humphrey, 

, 486-87 (1994) (ruling that, when
a state prisoner seeks damages in a § 1983 suit, the district court must consider
whether the judgment would necessarily imply invalidity of the conviction and, if it
would, must dismiss the case if plaintiff cannot demonstrate that conviction has
already been invalidated); Preiser v. Rodriguez, 

, 489-90 (1973)
(concluding a state prisoner challenging a conviction on federal constitutional grounds
is limited to habeas corpus); Swan v. Barbadoro, 

, 25-26 (1st Cir. 2008)
(per curiam) (declaring, where a judgment in plaintiff’s favor would impugn the
validity of his conviction, the plaintiff could not circumvent a Heck bar by bringing
claims under RICO).

      We deny Ryahim’s pending motion, and we affirm.
                    ______________________________
