SANDRA JANINE BUTLER, individually Case No. 1:25-cv-01011-CDB and as successor in interest of JACOB KOBER, ORDER GRANTING IN PART DEFENDANTS’ MOTION TO DISMISS Plaintiffs, (Doc. 9) v. 21-Day Deadline CALIFORNIA DEPARTMENT OF et al., Defendants. Pending before the Court1 is the motion of Defendants the California Department Corrections and Rehabilitation (“CDCR”), Kern Valley State Prison (“KVSP”), and Christian Pfeiffer (collectively, “Defendants”) to dismiss claims asserted in the first amended complaint (“FAC”) by Plaintiffs Sandra Janine Butler, individually and as successor in interest to Jacob Kober (“Decedent”). (Doc. 9). Plaintiffs filed an opposition to the motion to dismiss and Defendants filed a reply. (Docs. 11, 12). The motion was submitted before the undersigned on the record without hearing or oral argument, pursuant to Local Rule 230(g). (Doc. 22).

1 Following all parties’ expression of consent to the jurisdiction of a magistrate judge for all further proceedings in this action, including trial and entry of judgment, on December 11, 2025, this action was I. Background Plaintiffs filed the operative FAC on October 27, 2025. (Doc. 7). The FAC sets forth that, on April 28, 2015, Jacob Kober (“Decedent”) was booked as a detainee into Kern Valley State Prison in Delano California. Id. ¶ 23. On September 19, 2024, he was a cellmate of Matthew Perez, who was in prison for robbery and had previously been charged for attacking a cellmate. Id. ¶ 24. That day, Perez “finished a telephone call with his wife/girlfriend and was high, irate and belligerent.” Decedent attempted to calm Perez down but Perez attacked Kober with a makeshift weapon and stabbed him multiple times. The attack extended over a “long” period of time and attracted the attention of other inmates as Decedent called for help. Id. ¶ 25. During the time of the attack, the correctional officers (named as “Doe” Defendants one through 20), were in the correctional officer’s booth and “had shut the doors and windows which was a violation of the [CDCR] Department Operating Manual and the policies and procedures for their jobs because it prevented them from hearing anything occurring with the prisoners.” Id. ¶ 16. During the attack, Decedent “had been screaming for help” but the station windows of “Doe” Defendants one through 20 were “wrongfully closed and [they] could not hear the screaming, or heard the screaming but chose to ignore it.” Other inmates “were also screaming for the [‘Doe’ Defendants one through 20] to help [Decedent] but the [‘Doe’ Defendants] could not hear them because of the closed windows.” Id. ¶ 27. During the time of the attack, “Doe” Defendants one through 20 “had not been walking the halls every [30] minutes, which was a violation of the Department Operating Manual and the policies and procedures for their jobs because it prevented them from observing anything untoward occurring with the prisoners.” No such “Doe” Defendant “walked the halls for approximately [one] to 1.5 hours and it was only when the [‘Doe’ Defendants one through 20] resumed walking the halls at approximately 7:00 p.m. that [Decedent] was discovered on the floor after having bled out from the multiple stab wounds.” Id. ¶ 28. “Around 7:20 p.m., it was reported that jail personnel found [Decedent] unresponsive in a two-man cell with multiple wounds to his body, consistent with an incarcerated-manufactured weapon.” Id. ¶ 62. consistent with an incarcerated-manufactured weapon.” Decedent was “transported to the prison’s triage and treatment area for a higher level of care.” Decedent was pronounced dead by on-scene paramedics at 7:52 p.m. An “incarcerated-manufactured weapon was found at the scene.” Id. ¶ 29. Decedent’s cause of death was reported as “multiple stab wounds” on September 19, 2024. Id. ¶ 63. Prior to being placed in a cell with Decedent, Perez had “previously been housed in solitary confinement due to prior violent and aggressive behavior towards the correction officers and the other inmates.” Id. ¶ 31. Plaintiffs allege that staff at KVSP were aware that Perez was mentally unstable and posed a safety risk to Decedent and other prisoners. Id. ¶ 32. For instance, an unnamed KVSP employee stated that Perez was known to be highly unstable and had expressed surprise Perez was able to have a cellmate. Id. ¶ 33. Prior to the incident, there had been “multiple episodes of violence involving [Perez] which CDCR was well aware of but after which they refused to take action to protect [Decedent.” In one prior occasion, Decedent “entered the cell and found [Perez] covered in his own blood from self-inflicted injuries, making his mental instability[] and tendency for violence well known.” Despite the fact that “this incident [proved] to CDCR the presence of a weapon within the cell, no action was taken by CDCR to remove [Perez] and [Decedent] was forced to continue to share a cell with him …” Id. ¶ 34. On another occasion, Perez “lunged at [Decedent] in an attempt to harm him.” Decedent “tried to reason with [Perez] and calm him down. [Perez] was not detained or removed following this incident either, and [Decedent] was forced to continue sharing a cell with him” until the incident. Id. ¶ 35. Perez would become irate and aggressive during phone calls with his wife or girlfriend; the relationship was characterized by frequent breakups and reconciliations. Id. ¶ 36. Perez “often used illegal drugs” while at KVSP, which made his mental instability worse. Defendants did not “take any action to get [Perez] mental help, keep him separate from other inmates, or even confiscate his drugs.” Id. ¶ 37. Decedent “repeatedly shared with his mother” (Plaintiff Butler) and with his girlfriend “how miserable his living situation was and expressed frustration over [Perez’s] escalating mental instability.” Id. ¶ 38. “On virtually every call,” Plaintiff Butler and Decedent’s girlfriend “could hear [Perez] in the background yelling and screaming.” Id. ¶ 39. “Doe” Defendants one through 20 were responsible for classifying and assigning housing for Decedent, did not determine whether Decedent was at risk, exhibited deliberate indifference by closing the windows and doors of the correctional officers’ booth and by not walking the halls every 30 minutes as prescribed, failed to search persons entering facilities for contraband, failed to search the cell in which Decedent was housed for contraband, and failed to follow appropriate policies, training, standards, and procedures, including the CDCR’s operating manual. Id. ¶¶ 42-45, 50-52. “Doe” Defendants one through 20 were responsible for supervising inmates, including by monitoring CCTV cameras which provided a live video feed of Decedent’s cell to a control room, and failed to do so. Id. ¶¶ 53-55, 60. Said Defendants “were not making their usual inspections of the cells every 30 minutes and did not discovery [Decedent’s] body for [one] to 1.5 hours by which time[] [Decedent] had extreme blood loss due to the multiple stab wounds inflicted by [Perez].” Id. ¶ 58. “Sometime after September 19, 2024, it was reported that [Perez] had been charged with felony murder[] related to the death of [Decedent].” Id. ¶ 64. II. Governing Authority A motion to dismiss under Federal Rule of Civil Procedure 12(b)(6) asks a court to dismiss a plaintiff’s complaint for failing “to state a claim upon which relief can be granted.” Fed. R. Civ. P. 12(b)(6). A motion to dismiss under Rule 12(b)(6) tests the complaint’s sufficiency. N. Star Int’l v. Ariz. Corp. Comm’n., 720 F.2d 578, 581 (9th Cir. 1983) (citing Peck v. Hoff,
