THE ESTATE OF BRANDON YATES, Case No.: 25cv0410-W-MMP by and through its successors-in-interest, Dan Yates and Andrea Carrier; DAN ORDER DENYING IN PART AND YATES and ANDREA CARRIER, GRANTING IN PART THIRD- PARTY DEFENDANTS’ MOTION Plaintiffs, TO DISMISS [DOC. 45] v. MARTINEZ, in her individual capacity, RICH WILLIAMS, in his individual capacity, MATTHEW BLACKBURN, in his individual capacity, TONY GONZALES, in his individual capacity, and DOES 1-51, Defendants.

Third-Party Plaintiff, v. DR. HUDAD TOLLOUI; DR. REBECCA ROBINSON; DR. PETE J. FARRELL IV; MIRANDA EVANS; LIBERTY HEALTHCARE CORPORATION; CALIFORNIA, INC.; NAPHCARE OF SAN DIEGO, INC.; NAPHCARE, INC.; AND ROES 1-30, Third-Party Defendants. Pending before the Court is Third-Party Defendants NaphCare, Inc., NaphCare of San Diego, LLC (“NaphCare”), Dr. Hudad Tolloui (“Dr. Tolloui”), Dr. Rebecca Robinson (“Dr. Robinson”), Dr. Peter J. Farrell IV (“Dr. Farrell”) and Miranda Evans’ (“Evans”) (collectively the “Third-Party Defendants1”) motion to dismiss the third-party complaint under Federal Rule of Civil Procedure 12(b)(6). Third-Party Plaintiff the County of San Diego (“the County”) opposes the motion. The Third-Party Defendants filed a reply in support. The Court decides the matter on the papers submitted and without oral argument pursuant to Civil Local Rule 7.1(d)(1). For the following reasons, the Court DENIES IN PART and GRANTS IN PART the motion to dismiss [Doc. 45] WITH LEAVE TO This lawsuit arises from the death of twenty-four-year-old Brandon Yates (“Yates”) while in custody at the San Diego County Central Jail (“SDCJ”). (Original Complaint (“OC”) [Doc. 1] ¶¶ 68, 69, 117.) The Estate of Brandon Yates (“Plaintiffs”) asserts four causes of action under 42 U.S.C. § 1983, including deliberate indifference, failure to properly train, supervise, discipline, Monell liability, and violation of the right of association, as well as causes of action under the Bane Act, for negligence, and wrongful death. (See OC.) Yates was placed in a cell with Alvin Ruis (“Ruis”), another

1 The Court will later refer to Dr. Robinson, Dr. Tolloui, Dr. Farrell, and Evans, collectively as the inmate suffering from mental illness, who sexually assaulted, strangled, and smothered Yates to death. (Id. ¶¶ 70, 77, 79, 94–117.) Prior to his arrest, Ruis experienced psychotic episodes that resulted in involuntary hospitalizations in Montana and London. (Id. ¶¶ 32–35.) Shortly after his return home, Ruis assaulted his wife and children and was arrested on numerous charges. (OC ¶ 35.) At his arraignment, Ruis’ family requested that he receive help and expressed concern that he “would commit suicide or murder someone as he had threatened on multiple occasions.” (Id. ¶ 36.) Within his first few days at SDCJ, Ruis attempted to hang himself with a rope made from jail-supplied clothing and was placed in Enhanced Observational Housing (“EOH”). (Id. ¶ 42.) During his incarceration there, Ruis experienced auditory hallucinations and psychosis, displayed increasingly aggressive behavior, threatened suicide and violence against others, and assaulted a deputy. (Id. ¶¶ 38, 41, 44–46, 54–55.) Although Ruis was repeatedly declared a danger to himself or others and placed in EOH on multiple occasions, he was released back into mainline housing each time by medical providers (Does 37–46) “without further evaluation, medication, or monitoring.” (Id. ¶¶ 38–41, 57, 65.) Plaintiffs allege that Ruis was never placed in segregation housing or the Psychiatric Stabilization Unit (“PSU”), where mentally ill inmates are monitored constantly and involuntarily medicated if necessary. (Id. ¶¶ 43, 66.) Yates was booked into the SDCJ on suspicion of burglary. (OC ¶ 68.) Like Ruis, Yates suffered from mental illness, and his “nonsensical” speech caused his cellmates to become aggressive toward him. (Id. ¶¶ 71–72.) At his cellmates’ request, Deputy Blackburn transferred Yates out of the cell and placed him in a cell with Ruis despite alleged knowledge of both inmates’ conditions. (Id. ¶¶ 73–77.) Both Ruis and Yates allegedly suffered from “hyper-religiosity” and “spoke obsessively about God.” (Id. ¶ 79.) Yates believed he was Jesus, while Ruis believed Yates was the devil and told Yates that “he was going to kill him.” (Id. ¶¶ 79–80, 84.) Plaintiffs allege that although both inmates pressed the emergency intercom for help, deputies did not check on them for nearly an hour, during which time Ruis sexually assaulted, strangled, and killed Yates. (Id. ¶¶ 85–117.) On February 24, 2025, Plaintiffs filed a complaint against the County and several of its employees. (See OC.) On September 18, 2025, the County filed a TPC against NaphCare and Liberty Healthcare Corporation and Liberty Healthcare of California, Inc. (“Liberty Healthcare”) and several of its employees. (See TPC.) The TPC alleges that the County contracted with NaphCare to provide mental health services in County jails, and its employees allegedly provided care to Ruis and/or Yates. (Third-Party Complaint (“TPC”) [Doc. 20] ¶¶ 2–3.) The TPC further alleges that NaphCare, in turn, contracted with Liberty Healthcare2 to provide those same services, and its employees also allegedly provided care to Ruis and/or Yates. (Id. ¶¶ 4–5.) Third-Party Defendant Dr. Tolloui, a clinical psychologist, Third-Party Defendant Dr. Robinson, a registered psychological associate and/or licensed clinical psychologist, Third-Party Defendant Dr. Farrell, a psychiatrist, as well as Third-Party Defendant Evans, a clinical social worker, were employees of either NaphCare or Liberty Healthcare at the time of Yates’ death. (Id. ¶¶ 6–9.) The County’s TPC asserts causes of action for: (1) Breach of Contract as to Third- Party Defendant NaphCare; (2) Equitable Indemnity as to all Third-Party Defendants; and (3) Declaratory Relief as to all Third-Party Defendants. (See TPC.) The TPC incorporates the allegations of the OC in its entirety. (Id. at 7.) After the Third-Party Defendants filed the pending motion to dismiss, Plaintiffs filed a first amended complaint (“FAC”) [Doc. 66], which identifies many of the Doe Defendants, including Dr. Tolloui and Dr. Robinson as Does 38 and 39. (FAC ¶¶ 28, 59, 60, 102–109.) Because the TPC has not been amended to incorporate the FAC, the Court considers the FAC only to determine whether leave to amend should be granted.
