ECF No. 87. Plaintiff Barbara Brisson, 24 individually and as successor in interest to the Estate of Aaron Daniel Bonin, filed an 25 opposition to the Motion, to which Defendant replied. ECF Nos. 89, 90. The Court finds 26 this matter suitable for determination on the papers and without oral argument pursuant to 27 Federal Rule of Civil Procedure 78(b) and Civil Local Rule 7.1(d)(1). For the reasons stated 28 below, the Court DENIES David’s Motion to Dismiss. 1 I. BACKGROUND 2 The parties are well versed in the factual and procedural history of this case. On 3 September 1, 2022, Aaron Daniel Bonin (“Mr. Bonin”) was transferred from the 4 Department of State Hospitals forensic psychiatric facility in Patton, California to the San 5 Diego Central Jail (the “Jail”) for civil commitment reconsideration proceedings. ECF 6 No. 80 (“Third Amended Complaint” or “TAC”) ¶ 31. Mr. Bonin suffered from severe 7 mental illness and had been civilly committed for over a decade. Id. ¶ 2. He also suffered 8 from health conditions, including renal disease, which required dialysis two to three times 9 per week and a “renal diet.” Id. ¶¶ 2, 34. 10 On September 26, 2022, Mr. Bonin’s potassium level was 6.4 mmol/L, which is 11 “critically high,” and he was taken to the hospital for dialysis because the machines at the 12 Jail were not working. Id. ¶ 36. Plaintiff alleges that beginning on October 17, 2022, staff 13 at the Jail allowed Mr. Bonin to have a normal diet instead of a renal diet. Id. ¶ 37–39. On 14 October 19 or 20, Mr. Bonin’s bloodwork again revealed a dangerously high blood 15 potassium level: 6.3–6.4 mmol/L. Id. ¶ 41. Medical staff treated Mr. Bonin with dialysis 16 on October 21, but his dialysis was cut short that day. Id. ¶ 45. Mr. Bonin’s potassium 17 levels were not retested, and he did not receive dialysis, after October 21. Id. ¶ 74–75. 18 Mr. Bonin fell ill on the night of October 23, 2022. Id. ¶¶ 37–43, 84. At around 10:00 19 p.m. that evening, a nurse was asked by a deputy to check on Mr. Bonin. Id. ¶ 89. She 20 found him lying on the floor, and he told her: “I feel like I am having hypotension.” Id. 21 The nurse checked Mr. Bonin’s blood pressure, and after confirming his levels were 22 “okay,” she left. Id. Mr. Bonin continued to feel unwell and a few hours later he called out 23 for help, begging to go to the hospital. Id. ¶¶ 91–92. Throughout the night, Mr. Bonin’s 24 pleas were ignored. Id. ¶¶ 97–100. 25 Mr. Bonin’s cries for help “fell silent around 3:00 a.m. on October 24, 2022.” 26 Id. ¶ 102. While conducting routine safety checks, deputies found Mr. Bonin unresponsive 27 on the floor of his cell around 3:16 a.m. that morning. Id. ¶ 105. Life-saving efforts were 28 employed, and medical staff arrived at 3:23 a.m. Id. ¶ 106. Fire Department personnel 1 responded at around 3:31 a.m., and Mr. Bonin was taken and admitted to the University of 2 California, San Diego – Hillcrest hospital in critical condition. Id. ¶¶ 108, 128. 3 In the emergency room, Mr. Bonin’s blood potassium level was recorded at 4 8.0 mmol/L. Id. ¶ 130. According to medical records, Mr. Bonin had suffered cardiac arrest 5 and “had been down for approximately ten minutes prior to deputies beginning CPR.” 6 Id. ¶ 129. A subsequent MRI revealed “diffuse hypoxic ischemic injury, which is a brain 7 injury that results from prolonged lack of oxygen.” Id. ¶ 131. Mr. Bonin was pronounced 8 dead on November 1, 2022. Id. ¶ 132. 9 Plaintiff is Mr. Bonin’s mother, see id. ¶ 9, and she brings this action challenging 10 the actions and inactions of various individuals during the time that Mr. Bonin was at the 11 Jail. In the TAC, Plaintiff alleges the following six claims: (1) as successor in interest, for 12 deliberate indifference in violation of the Fourteenth Amendment pursuant to 42 U.S.C. 13 § 1983; (2) as an individual, for violation of the Fourteenth Amendment, substantive due 14 process pursuant to 42 U.S.C. § 1983; (3) as an individual, for deliberate indifference in 15 violation of the Fourteenth Amendment pursuant to Monell; (4) as an individual, for 16 violation of the Fourteenth Amendment, substantive due process, pursuant to Monell; (5) as 17 successor in interest, for violation of the Bane Act, Cal. Gov. Code § 52.1; and (6) as an 18 individual for wrongful death. 19 II. LEGAL STANDARDS 20 Rule 12(b)(6)1 permits a party to raise by motion the defense that the complaint 21 “fail[s] to state a claim upon which relief can be granted,” generally referred to as a motion 22 to dismiss. The Court evaluates whether a complaint states a cognizable legal theory and 23 sufficient facts in light of Rule 8(a), which requires a “short and plain statement of the 24 claim showing that the pleader is entitled to relief.” Although Rule 8 “does not require 25 ‘detailed factual allegations,’” it does require “more than an unadorned, the-defendant- 26 27 1 The term “Rule” refers to the Federal Rules of Civil Procedure, unless otherwise 28 1 unlawfully-harmed-me accusation.” Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009) (quoting 2 Bell Atl. Corp. v. Twombly, 550 U.S. 544, 555 (2007)). A “formulaic recitation of the 3 elements of a cause of action” is insufficient. Id. (quoting Twombly, 550 U.S. at 555). “Nor 4 does a complaint suffice if it tenders ‘naked assertion[s]’ devoid of ‘further factual 5 enhancement.’” Id. (alteration in original) (quoting Twombly, 550 U.S. at 557). 6 In reviewing the plausibility of a complaint, courts “accept factual allegations in the 7 complaint as true and construe the pleadings in the light most favorable to the nonmoving 8 party.” Manzarek v. St. Paul Fire & Marine Ins. Co., 519 F.3d 1025, 1031 (9th Cir. 2008). 9 Nonetheless, courts do not “accept as true allegations that are merely conclusory, 10 unwarranted deductions of fact, or unreasonable inferences.” In re Gilead Scis. Secs. Litig., 11 536 F.3d 1049, 1055 (9th Cir. 2008) (quoting Sprewell v. Golden State Warriors, 12 266 F.3d 979, 988 (9th Cir. 2001)). The Court also need not accept as true allegations that 13 contradict matter properly subject to judicial notice or allegations contradicting the exhibits 14 attached to the complaint. Sprewell, 266 F.3d at 988.
