1 2 3 4 5 6 7 8 UNITED STATES DISTRICT COURT 9 EASTERN DISTRICT OF CALIFORNIA 10 11 SANDRA JANINE BUTLER, individually Case No. 1:25-cv-01011-CDB and as successor in interest of JACOB 12 KOBER, ORDER GRANTING IN PART DEFENDANTS’ MOTION TO DISMISS 13 Plaintiffs, 14 (Doc. 9) v. 15 21-Day Deadline CALIFORNIA DEPARTMENT OF 16 CORRECTIONS AND REHABILITATION, et al., 17 Defendants. 18 19 20 Pending before the Court1 is the motion of Defendants the California Department 21 Corrections and Rehabilitation (“CDCR”), Kern Valley State Prison (“KVSP”), and Christian 22 Pfeiffer (collectively, “Defendants”) to dismiss claims asserted in the first amended complaint 23 (“FAC”) by Plaintiffs Sandra Janine Butler, individually and as successor in interest to Jacob Kober 24 (“Decedent”). (Doc. 9). Plaintiffs filed an opposition to the motion to dismiss and Defendants filed 25 a reply. (Docs. 11, 12). The motion was submitted before the undersigned on the record without 26 hearing or oral argument, pursuant to Local Rule 230(g). (Doc. 22).

27 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 1 I. Background 2 Plaintiffs filed the operative FAC on October 27, 2025. (Doc. 7). The FAC sets forth that, 3 on April 28, 2015, Jacob Kober (“Decedent”) was booked as a detainee into Kern Valley State 4 Prison in Delano California. Id. ¶ 23. On September 19, 2024, he was a cellmate of Matthew 5 Perez, who was in prison for robbery and had previously been charged for attacking a cellmate. Id. 6 ¶ 24. That day, Perez “finished a telephone call with his wife/girlfriend and was high, irate and 7 belligerent.” Decedent attempted to calm Perez down but Perez attacked Kober with a makeshift 8 weapon and stabbed him multiple times. The attack extended over a “long” period of time and 9 attracted the attention of other inmates as Decedent called for help. Id. ¶ 25. During the time of 10 the attack, the correctional officers (named as “Doe” Defendants one through 20), were in the 11 correctional officer’s booth and “had shut the doors and windows which was a violation of the 12 [CDCR] Department Operating Manual and the policies and procedures for their jobs because it 13 prevented them from hearing anything occurring with the prisoners.” Id. ¶ 16. 14 During the attack, Decedent “had been screaming for help” but the station windows of 15 “Doe” Defendants one through 20 were “wrongfully closed and [they] could not hear the 16 screaming, or heard the screaming but chose to ignore it.” Other inmates “were also screaming for 17 the [‘Doe’ Defendants one through 20] to help [Decedent] but the [‘Doe’ Defendants] could not 18 hear them because of the closed windows.” Id. ¶ 27. During the time of the attack, “Doe” 19 Defendants one through 20 “had not been walking the halls every [30] minutes, which was a 20 violation of the Department Operating Manual and the policies and procedures for their jobs 21 because it prevented them from observing anything untoward occurring with the prisoners.” No 22 such “Doe” Defendant “walked the halls for approximately [one] to 1.5 hours and it was only when 23 the [‘Doe’ Defendants one through 20] resumed walking the halls at approximately 7:00 p.m. that 24 [Decedent] was discovered on the floor after having bled out from the multiple stab wounds.” Id. 25 ¶ 28. “Around 7:20 p.m., it was reported that jail personnel found [Decedent] unresponsive in a 26 two-man cell with multiple wounds to his body, consistent with an incarcerated-manufactured 27 weapon.” Id. ¶ 62. 1 consistent with an incarcerated-manufactured weapon.” Decedent was “transported to the prison’s 2 triage and treatment area for a higher level of care.” Decedent was pronounced dead by on-scene 3 paramedics at 7:52 p.m. An “incarcerated-manufactured weapon was found at the scene.” Id. ¶ 4 29. Decedent’s cause of death was reported as “multiple stab wounds” on September 19, 2024. Id. 5 ¶ 63. Prior to being placed in a cell with Decedent, Perez had “previously been housed in solitary 6 confinement due to prior violent and aggressive behavior towards the correction officers and the 7 other inmates.” Id. ¶ 31. 8 Plaintiffs allege that staff at KVSP were aware that Perez was mentally unstable and posed 9 a safety risk to Decedent and other prisoners. Id. ¶ 32. For instance, an unnamed KVSP employee 10 stated that Perez was known to be highly unstable and had expressed surprise Perez was able to 11 have a cellmate. Id. ¶ 33. Prior to the incident, there had been “multiple episodes of violence 12 involving [Perez] which CDCR was well aware of but after which they refused to take action to 13 protect [Decedent.” In one prior occasion, Decedent “entered the cell and found [Perez] covered 14 in his own blood from self-inflicted injuries, making his mental instability[] and tendency for 15 violence well known.” Despite the fact that “this incident [proved] to CDCR the presence of a 16 weapon within the cell, no action was taken by CDCR to remove [Perez] and [Decedent] was 17 forced to continue to share a cell with him …” Id. ¶ 34. 18 On another occasion, Perez “lunged at [Decedent] in an attempt to harm him.” Decedent 19 “tried to reason with [Perez] and calm him down. [Perez] was not detained or removed following 20 this incident either, and [Decedent] was forced to continue sharing a cell with him” until the 21 incident. Id. ¶ 35. Perez would become irate and aggressive during phone calls with his wife or 22 girlfriend; the relationship was characterized by frequent breakups and reconciliations. Id. ¶ 36. 23 Perez “often used illegal drugs” while at KVSP, which made his mental instability worse. 24 Defendants did not “take any action to get [Perez] mental help, keep him separate from other 25 inmates, or even confiscate his drugs.” Id. ¶ 37. Decedent “repeatedly shared with his mother” 26 (Plaintiff Butler) and with his girlfriend “how miserable his living situation was and expressed 27 frustration over [Perez’s] escalating mental instability.” Id. ¶ 38. 1 “On virtually every call,” Plaintiff Butler and Decedent’s girlfriend “could hear [Perez] in 2 the background yelling and screaming.” Id. ¶ 39. “Doe” Defendants one through 20 were 3 responsible for classifying and assigning housing for Decedent, did not determine whether 4 Decedent was at risk, exhibited deliberate indifference by closing the windows and doors of the 5 correctional officers’ booth and by not walking the halls every 30 minutes as prescribed, failed to 6 search persons entering facilities for contraband, failed to search the cell in which Decedent was 7 housed for contraband, and failed to follow appropriate policies, training, standards, and 8 procedures, including the CDCR’s operating manual. Id. ¶¶ 42-45, 50-52. 9 “Doe” Defendants one through 20 were responsible for supervising inmates, including by 10 monitoring CCTV cameras which provided a live video feed of Decedent’s cell to a control room, 11 and failed to do so. Id. ¶¶ 53-55, 60. Said Defendants “were not making their usual inspections of 12 the cells every 30 minutes and did not discovery [Decedent’s] body for [one] to 1.5 hours by which 13 time[] [Decedent] had extreme blood loss due to the multiple stab wounds inflicted by [Perez].” 14 Id. ¶ 58. “Sometime after September 19, 2024, it was reported that [Perez] had been charged with 15 felony murder[] related to the death of [Decedent].” Id. ¶ 64. 16 II. Governing Authority 17 A motion to dismiss under Federal Rule of Civil Procedure 12(b)(6) asks a court to dismiss 18 a plaintiff’s complaint for failing “to state a claim upon which relief can be granted.” Fed. R. Civ. 19 P. 12(b)(6). A motion to dismiss under Rule 12(b)(6) tests the complaint’s sufficiency. N.
