v.

Nikolaus Arney, et al.,

Defendants. Pending before the Court is Defendant Maricopa County Community College District Police Department’s (“MCCCD PD”) Motion to Dismiss (Doc. 20), Defendants Nikolaus Arney and Kyran Brennan’s Motion to Dismiss (Doc. 21), and Defendant Cory Trufant’s Motion to Dismiss (Doc. 24). The matters are fully briefed and the Court now rules. This case arises from an incident in which Andre Lamar Lindsey Jr. (the “Decedent”) was shot and killed by MCCCD Police Sergeant Nikolaus Arney on March 7, 2024. (Doc. 8 at 6 ¶ 28, 11 ¶ 67, 12 ¶ 72, 20 ¶¶ 127–28, 22). Plaintiff Susan Y. Lindsey, the Decedent’s mother, brings this action in her personal capacity. (Doc. 8 at 2, 24). A. Factual Background Plaintiff alleges that on March 7, 2024, Defendant Arney fatally shot the Decedent while on duty as an MCCCD Police Sergeant (Doc. 8 at 6 ¶ 28, 11 ¶ 67, 12 ¶ 72, 20 ¶¶ 127– 28), and that Defendant Arney’s use of deadly force was not justified under the circumstances. (Doc. 8 at 22–23). Plaintiff alleges that MCCCD Police Chief Kyran Brennan was also present during the incident, and that Defendants Arney and Brennan failed to render immediate medical assistance to the Decedent before emergency medical personnel arrived. (Doc. 8 at 23). Plaintiff further alleges that the incident was investigated by the Arizona Department of Public Safety (“DPS”), and that Detective Cory Trufant was the lead investigator. (Doc. 8 at 2, 22). Plaintiff alleges that Defendant Trufant did not properly preserve or document the handling of evidence from the investigation. (Doc. 8 at 22, 26). B. Procedural History Plaintiff filed a Complaint on February 24, 2026 (Doc. 1) and subsequently filed a First Amended Complaint (“FAC”) on April 9, 2026 (Doc. 8) against Defendants MCCCD PD, Arney, Brennan, and Trufant. Count 1 alleges a 42 U.S.C. § 1983 Excessive Force claim against Defendant Arney (Doc. 8 at 22); Count 2 alleges a § 1983 “Failure to Render Medical Aid” claim against Defendants Arney and Brennan (Doc. 8 at 23); Count 3 alleges a Wrongful Death claim under A.R.S. § 12-611 et seq. against all Defendants (Doc. 8 at 24); Count 4 alleges Negligence and Gross Negligence against all Defendants (Doc. 8 at 24); Count 5 alleges § 1983 “Municipal Liability” against Defendant MCCCD PD (Doc. 8 at 25); and Count 6 alleges a § 1983 Due Process claim against Defendant Trufant (Doc. 8 at 26). On June 4, 2026, Defendant MCCCD PD filed a Motion to Dismiss (Doc. 20), to which Plaintiff responded (Doc. 25), and Defendant MCCCD PD replied (Doc. 29). Also on June 4, 2026, Defendants Arney and Brennan filed a Motion to Dismiss (Doc. 21), to which Plaintiff responded (Doc. 26), and Defendants Arney and Brennan replied (Doc. 28). On June 26, 2026, Defendant Trufant filed a Motion to Dismiss (Doc. 24), to which Plaintiff responded (Doc. 27), and Defendant Trufant replied (Doc. 30). A. Federal Rule of Civil Procedure 12(b)(6) “[T]o survive a motion to dismiss under Rule 12(b)(6), a party must allege sufficient factual matter, accepted as true, to state a claim to relief that is plausible on its face.” In re Fitness Holdings Int’l, Inc., 714 F.3d 1141, 1144 (9th Cir. 2013) (internal quotation marks omitted). “A claim has facial plausibility when the plaintiff pleads factual content that allows the court to draw the reasonable inference that the defendant is liable for the misconduct alleged.” Id. (quoting Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009)). A complaint will be dismissed for failure to state a claim if it lacks either “a cognizable legal theory or . . . sufficient facts alleged under a cognizable legal theory.” Balistreri v. Pacifica Police Dep’t, 901 F.2d 696, 699 (9th Cir. 1988). “All well-pleaded allegations of material fact in the complaint are accepted as true and are construed in the light most favorable to the non-moving party.” Faulkner v. ADT Sec. Servs., Inc., 706 F.3d 1017, 1019 (9th Cir. 2013). However, the court need not accept legal conclusions couched as factual allegations, and “[t]hreadbare recitals of the elements of a cause of action, supported by mere conclusory statements, do not suffice.” Iqbal, 556 U.S. at 678–80. In considering a 12(b)(6) motion to dismiss, courts ordinarily may not consider evidence outside the pleadings without converting the motion into a Rule 56 motion for summary judgment. United States v. Ritchie, 342 F.3d 903, 907 (9th Cir. 2003). “A court may, however, consider certain materials—documents attached to the complaint, documents incorporated by reference in the complaint, or matters of judicial notice— without converting the motion to dismiss into a motion for summary judgment.” Id. Moreover, “[a] document filed pro se is to be liberally construed, and a pro se complaint, however inartfully pleaded, must be held to less stringent standards than formal pleadings drafted by lawyers.” Erickson v. Pardus, 551 U.S. 89, 94 (2007) (internal quotation marks and citations omitted); Hebbe v. Pliler, 627 F.3d 338, 342 (9th Cir. 2010) (instructing that courts should “construe pro se filings liberally . . . , particularly in civil rights cases” (internal quotation marks and citation omitted)). B. Federal Rule of Civil Procedure 12(b)(1) Rule 12(b)(1) allows a defendant to raise the defense that the court lacks jurisdiction over the subject matter of an entire action or of specific claims alleged in the action. When considering a motion to dismiss for lack of subject matter jurisdiction, the Court takes as true the material facts alleged in the complaint. See Whisnant v. United States, 400 F.3d 1177, 1179 (9th Cir. 2005). But the Court is not restricted to the face of the pleadings; it may consider affidavits to resolve any factual disputes concerning the existence of jurisdiction. McCarthy v. United States, 850 F.2d 558, 560 (9th Cir. 1988); see Biotics Research Corp. v. Heckler, 710 F.2d 1375, 1379 (9th Cir. 1983) (consideration of material outside the pleadings did not convert a Rule 12(b)(1) motion into one for summary judgment). If a defendant files a Rule 12(b)(1) motion attacking the existence of subject matter jurisdiction, the plaintiff bears the burden of proving that jurisdiction exists. Thornhill Publ’g Co. v. Gen. Tel. & Elecs. Corp., 594 F.2d 730, 733 (9th Cir. 1979). C. Federal Rules of Civil Procedure 12(b)(2) & 12(b)(5) A motion to dismiss under Rule 12(b)(2) challenges the Court’s personal jurisdiction over the defendant and the plaintiff bears the burden of establishing that jurisdiction is proper. Schwarzenegger v. Fred Martin Motor Co., 374 F.3d 797, 800 (9th Cir. 2004). A motion under Rule 12(b)(5) challenges the sufficiency of service of process. The plaintiff likewise bears the burden of establishing that service was proper. Brockmeyer v. May, 383 F.3d 798, 801 (9th Cir. 2004). III. DEFENDANTS ARNEY AND BRENN
