Brandon Scott Lavergne, Louisiana prisoner # 424229, pleaded guilty to two counts of first degree murder for the murders of Michaela Shunick and Lisa Pate. Thereafter, Lavergne filed a civil rights complaint against Mike Harson, the District Attorney for the Fifteenth Judicial District, and the Office of the District Attorney for the Fifteenth Judicial District. The district court dismissed the complaint as barred by Heck v. Humphrey, 512 U.S. 477, 114 S.Ct. 2364, 129 L.Ed.2d 383 (1994), and, alternatively, for failure to state a claim because District Attorney Harson was entitled to absolute prosecuto-rial immunity and the District Attorney’s *362 Office was not an entity capable of being sued under 42 U.S.C. § 1983. Additionally, the district court dismissed Lavergne’s claims he assei’ted under Louisiana state law without prejudice.

This court reviews a dismissal for failure to state a claim under 28 U.S.C. § 1915(e)(2)(B)(ii) de novo applying the same standard that is used to review a dismissal under Federal Rule of Civil Procedure 12(b)(6). Black v. Warren, 134 F.3d 732, 733-34 (5th Cir. 1998).

Lavergne’s motion for leave to ñle a supplemental brief is GRANTED. In his briefs, Lavernge contends that his claims for libel, slander, malicious prosecution, release of false information and statements, and return of personal belongings are not grounds to overturn his convictions and, therefore, that Heck does not apply. We disagree. Lavergne’s claims arise out of the appellees’ prosecutions of him for murder. If the district court were to award him damages as to any of these claims, it would implicitly call into question the validity of his convictions. See Heck, 512 U.S. at 487, 114 S.Ct. 2364; Penley v. Collin County, Tex., 446 F.3d 572, 573 (5th Cir. 2006). In this same vein, the district court did not abuse its discretion in denying his motions to amend his complaint because the amendments were futile in light of the Heck bar. Leal v. McHugh, 731 F.3d 405, 417 (5th Cir. 2013). The district court did not err in dismissing Lavergne’s Nee/c-barred claims with prejudice. See Johnson v. McElveen, 101 F.3d 423, 424 (5th Cir. 1996).

Finally, to the extent Lavergne raises new claims on appeal, we do not address them. See Williams v. Ballard, 466 F.3d 330, 335 (5th Cir. 2006). His motion to appoint counsel is DENIED.

AFFIRMED.
