Rapper Sues California Prison System Over Stabbing Incident

April 15, 2026 · Bryson Dawwell

Rapper Tory Lanez has launched a $100 million lawsuit against California’s Department of Corrections after a brutal stabbing attack whilst imprisoned at the California Correctional Institute in Tehachapi last May. The artist, born Daystar Peterson and presently completing a 10-year prison term for the 2020 shooting incident involving Megan Thee Stallion, was stabbed 16 times by fellow inmate Santino Casio in what the lawsuit describes as an “unprovoked dangerous assault.” The attack left Peterson hospitalised with a collapsed lung and numerous stabbing injuries to his back, torso, and head. The lawsuit names the Department of Corrections, the facility warden, and guards as respondents, alleging negligence in housing decisions and a delayed response to the violence.

The May 2025 Attack and Its Aftermath

The May 2025 stabbing incident at Tehachapi marked a watershed moment in Peterson’s incarceration. According to the lawsuit, fellow inmate Santino Casio, who was completing a life sentence for second-degree murder, launched an unprovoked assault that left the rapper fighting for his life. Peterson sustained a collapsed lung alongside multiple stab wounds across his back, torso, and head—injuries severe enough to warrant emergency hospitalisation. The attack raised significant concerns about prison security protocols and inmate classification procedures, particularly given the dangerous situation of housing two inmates with such markedly different profiles and threat levels.

Following his recovery, Peterson was moved to San Luis Obispo County’s California Men’s Colony, marking another chapter in his prison ordeal. The lawsuit further alleges that during this relocation, Peterson did not regain his personal items from Tehachapi, including songbooks featuring lyrics to unpublished songs—a loss that exacerbates the psychological and physical harm of the assault. Notably, despite the seriousness of the assault, Casio was not prosecuted in connection with the stabbing, a detail the lawsuit highlights as part of institutional breakdowns within the correctional system.

  • Casio attacked Peterson 16 times during the unprovoked incident
  • Peterson admitted to hospital with punctured lung and multiple wounds
  • Transferred to California Men’s Colony upon recovery
  • Personal belongings, including songbooks, not recovered from Tehachapi

Accusations of Negligence and Systemic Failure

Housing Options and Safety Issues

At the heart of Peterson’s lawsuit lies a fundamental challenge of the Corrections Department’s decision process regarding prisoner accommodation placements. The legal filing contends that placing Peterson alongside Santino Casio—a lifer incarcerated for second-degree murder—represented a severe breakdown in risk evaluation and prisoner classification. The lawsuit maintains that the department “ought to have been aware” to identify the inherent risk in this arrangement. Peterson’s high-profile celebrity status, the suit contends, made him an clear target within the prison facility, making the housing decision not merely negligent but recklessly indifferent to his wellbeing and safety.

The lawsuit emphasises that such placement choices require careful consideration of prisoner histories, threat levels, and underlying reasons for violence. By not segregating Peterson from Casio, facility management purportedly showed a widespread neglect for fundamental security procedures that must oversee California’s detention centres. This breach of care, the legal team contends, directly precipitated the conditions under which the stabbing took place, changing what could have stayed preventable violence into an entirely foreseeable consequence of organisational negligence and insufficient safety provisions.

Response and Security Conduct

Beyond the primary accommodation decision, the lawsuit targets prison guards’ response during the actual assault. According to the filing, correctional officers were slow to intervene when Casio launched his attack, allowing the violence to escalate unchecked. The lawsuit directly challenges the failure to use flash grenades or other non-lethal tactical measures that might have halted the assault before Peterson suffered his worst injuries. This alleged sluggishness in responding to an ongoing stabbing attack suggests either poor preparation, insufficient staffing, or a troubling disregard for prisoner safety—each possibility reflecting poorly on institutional competence.

The guards’ actions during the critical minutes of the attack calls into question emergency procedures and staff preparedness within California’s prison system. Conventional correctional practices generally require immediate intervention to violent incidents, yet the lawsuit indicates this incident significantly departed from such protocols. The combined impact of slow response times and the failure to implement proper tactical measures meant that Peterson’s 16 stab wounds were inflicted with scant active defence from security personnel, converting what could have been a grave occurrence into a critical emergency demanding hospital treatment.

The Expanded Context of Lanez’s Confinement

Tory Lanez’s current imprisonment stems from a widely publicized shooting event in 2020 involving fellow rapper Megan Thee Stallion. The confrontation, which occurred during the summer of 2020, led to Peterson shooting Stallion in the foot. Following a lengthy legal process, he was found guilty in December 2022 on several firearms charges, such as assault using a firearm, and subsequently sentenced to a ten-year prison sentence. This conviction represented a significant moment in hip-hop, attracting extensive press coverage and sparking considerable debate across the music sector regarding accountability and the circumstances surrounding the incident.

Peterson’s court disputes have persisted during his incarceration, with his legal team lodging an appeal challenging the conviction and sentence. However, in November 2025, a three-judge panel rejected his appeal and maintained the 10-year sentence originally imposed, effectively closing what many anticipated as an avenue for release or reduction in sentence. This denial came roughly six months after the stabbing attack at Tehachapi, meaning Peterson was dealing with both the psychological and physical aftermath of the prison attack whilst at the same time dealing with the disappointment of his failed appellate challenge. The combination of these events has significantly complicated his circumstances within the California correctional system.

Lawful Claims and Damages Claimed

Tory Lanez’s court action against the California Department of Corrections pursues $100 million in damages, representing one of the most significant cases filed against the state’s correctional system in the past several years. The legal action names the Department of Corrections as the main defendant, in addition to the warden and correctional officers stationed at the California Correctional Institute in Tehachapi. The lawsuit asserts that widespread deficiencies in prison management and safety measures resulted in the severity of Peterson’s injuries during the 2025 stabbing attack. The substantial compensation figure reflects both the bodily harm sustained and the emotional harm of the unprovoked assault.

At the heart of the lawsuit’s arguments is the assertion that prison authorities made a dangerously inadequate choice in housing Peterson with fellow inmate Santino Casio, who was serving a life sentence for second-degree murder. The court documents contends that the correctional department either knew or ought to have recognised that this housing arrangement posed a significant risk to Peterson, especially given his prominent inmate status within the facility. Furthermore, the lawsuit challenges the response of security personnel, contending that guards did not use appropriate emergency measures such as flash grenades to halt Casio’s assault. Notably, Casio was never charged with the assault despite inflicting 16 injuries on Peterson.

  • Correctional Department did not stop identified high-risk inmate pairing
  • Celebrity status made Peterson an identifiable target for attack
  • Security personnel were slow to respond to stabbing incident
  • Prison failed to employ flash grenades or alternative security measures
  • Peterson’s personal possessions, such as unreleased songbooks, are unaccounted for
