OPINION * ___________

* This disposition is not an opinion of the full Court and pursuant to I.O.P. 5.7 does not constitute binding precedent. PER CURIAM

Appellant Ronnie C. Williams, a Delaware state prisoner proceeding pro se,

appeals from the District Court’s dismissal of his civil rights complaint. For the reasons

that follow, we will affirm the District Court’s judgment.

Williams is currently serving a 22-year prison sentence for sexually abusing two

children, A.G. and E.S.H. Williams v. State, 296 A.3d 895, 899 (Del. 2023). On

September 27, 2019, Williams was arrested on 22 charges related to his sexual abuse of

both victims. On October 25, 2021, he was reindicted on an additional charge of sexual

solicitation of A.G. On November 19, 2021, a jury convicted Williams of rape in the

second degree, continuous sexual abuse of a child, unlawful sexual contact, sexual

solicitation of a child, and sexual abuse of a child by a person in a position of trust. 1 Id.

In November 2021, Williams brought a civil rights action against defendants from

the New Castle County Police Department and the Delaware Attorney General’s Office,

namely, Deputy Attorneys General Kelly Sheridan and Diana Dunn, and Detectives

Joshuah Smith and Keith Sydnor. He alleged that the criminal investigation and

prosecution which resulted in his current incarceration violated the United States

Constitution and the Delaware Constitution by malicious prosecution and abuse of

process. He also raised a state-law claim of intentional infliction of emotional distress.

1 The jury acquitted Williams of the charges involving the abuse of his nephew, A.D. See Williams, 296 A.3d at 905. Williams does not discuss these charges in his complaint outside of mentioning that, of the crimes he was charged with, five counts related “to a third party.” His complaint indicates that he was acquitted on charges related to A.G. and E.S.H., not A.D. 2 The defendants moved to dismiss Williams’s complaint under Federal Rule of Civil

Procedure 12(b)(6) on the grounds of prosecutorial immunity, qualified immunity, and

failure to state a claim. Williams filed a response in opposition.

The District Court granted the motions and dismissed the complaint with prejudice

for a variety of reasons. Williams appealed.

We have jurisdiction under 28 U.S.C. § 1291. Our review of a District Court’s

decision to grant a Rule 12(b)(6) motion to dismiss for failure to state a claim is plenary.

See Curry v. Yachera, 835 F.3d 373, 377 (3d Cir. 2016). To survive a motion to dismiss,

the complaint and any attached exhibits must contain enough facts that, if accepted as

true, state a claim for relief that is plausible on its face. Clark v. Coupe, 55 F.4th 167, 178

(3d Cir. 2022). 2 We “accept all factual allegations as true and construe the complaint in

the light most favorable to the plaintiff.” Curry, 835 F.3d at 377. “[W]e may affirm on

any basis supported by the record[.]” Stringer v. Cnty. of Bucks, 141 F.4th 76, 84 (3d Cir.

2025) (citing TD Bank N.A. v. Hill, 928 F.3d 259, 270 (3d Cir. 2019)). Because Williams

is proceeding pro se, we construe his filings liberally. See Erickson v. Pardus, 551 U.S.

89, 94 (2007) (per curiam). However, pro se litigants still must “abide by the same rules

that apply to all other litigants.” Mala v. Crown Bay Marina, Inc., 704 F.3d 239, 245 (3d

Cir. 2013).

2 Dismissal under Rule 12(b)(6) may be appropriate where an affirmative defense is apparent on the face of the complaint. Schmidt v. Skolas, 770 F.3d 241, 249 (3d Cir. 2014). 3 Williams raises four issues on appeal: (1) whether the District Court erred in

applying Heck v. Humphrey; (2) whether the District Court erred by invoking the Rooker-

Feldman doctrine; (3) whether the District Court correctly determined that defendants

Dunn’s and Sheridan’s actions fell within the scope of prosecutorial immunity; and (4)

whether the statute of limitations should have been tolled due to a “continuing violation

of rights.” None have merit.

We understand the District Court to have stated that, to the extent Williams’s

malicious-prosecution claims challenge the investigation and the prosecution that resulted

in his convictions, such claims are barred by Heck v. Humphrey, 512 U.S. 477 (1994).

See Williams v. Consovoy, 453 F.3d 173, 177 (3d Cir. 2006) (explaining that Heck bars

§ 1983 actions where success in the action would implicitly call into question the validity

of the plaintiff’s conviction or duration of sentence). The District Court did not purport to

use Heck as the dispositive reason for dismissal of Williams’s complaint, but correctly

observed that, to the extent his claims challenge the investigation and the prosecution that

resulted in his convictions, such claims are barred. Similarly, we understand the District

Court not to have relied on Rooker-Feldman as a basis for dismissal, but instead to have

merely observed that the doctrine would bar direct appellate-type review of the

underlying state-court judgments. See Rooker v. Fid. Trust Co., 263 U.S. 413 (1923);

D.C. Ct. of Appeals v. Feldman, 460 U.S. 462 (1983). To the extent that Williams’s

claims concern charges for which he was not convicted, they fail for the reasons set forth

below.

4 We agree with the District Court’s dismissal of all claims against defendants

Sheridan and Dunn. Prosecutorial immunity shields prosecutors from civil liability for all

acts taken while “functioning as the state’s advocate.” Odd v. Malone, 538 F.3d 202, 208

(3d Cir. 2008). Williams argues, without supporting fact or case law, that he “believes”

defendants do not qualify for immunity. 3 However, the constitutional claims against
