Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has launched a $100 million legal action against California’s Department of Corrections following a severe stabbing incident whilst imprisoned at the California Correctional Institute in Tehachapi last May. The artist, born Daystar Peterson and presently completing a 10-year sentence for the 2020 shooting incident involving Megan Thee Stallion, was struck 16 times with a blade by prison inmate Santino Casio in what the lawsuit characterises as an “unprovoked life-threatening attack.” The assault left Peterson admitted to hospital with a collapsed lung and multiple stab wounds to his back, torso, and head. The lawsuit names the Department of Corrections, the facility warden, and guards as defendants, alleging negligence in housing decisions and a slow reaction to the violence.

The May 2025 Incident and Its Consequences

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 struggling to survive. Peterson sustained a punctured lung alongside several stab injuries across his back, torso, and head—injuries serious 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 return to health, Peterson was relocated to San Luis Obispo County’s California Men’s Colony, marking another chapter in his time in custody. The lawsuit further contends that during this relocation, Peterson did not regain his personal possessions from Tehachapi, including songbooks featuring lyrics to unreleased compositions—a loss that compounds the psychological and physical harm of the incident. Notably, despite the gravity of the incident, Casio was not prosecuted in connection with the stabbing, a detail the lawsuit highlights as part of systemic failures within the correctional system.

• Casio struck Peterson 16 times during the unprovoked attack
• Peterson hospitalised with punctured lung and several lacerations
• Moved to California Men’s Colony upon recovery
• Personal possessions, including songbooks, not recovered from Tehachapi

Accusations of Negligence and Systemic Failure

Accommodation Choices and Safety Issues

At the heart of Peterson’s lawsuit sits a core criticism of the Department of Corrections’ decision-making concerning prisoner accommodation placements. The court document contends that placing Peterson alongside Santino Casio—a lifer incarcerated for second-degree murder—represented a catastrophic failure in risk evaluation and prisoner classification. The lawsuit argues that the department “knew or should have been known” to recognise the danger inherent in this pairing. Peterson’s high-profile celebrity status, the suit contends, made him an obvious target inside the correctional facility, making the housing decision not simply negligent but callously indifferent to his wellbeing and safety.

The lawsuit underscores that such placement choices demand thorough evaluation of inmate backgrounds, security classifications, and possible drivers for violence. By failing to separate Peterson from Casio, correctional officials allegedly demonstrated a institutional indifference for basic safety protocols that must oversee California’s correctional facilities. This failure of duty, the counsel contends, substantially contributed to the conditions under which the stabbing took place, transforming what should have been preventable violence into an entirely foreseeable consequence of organisational negligence and inadequate protective measures.

Response and Security Conduct

Beyond the initial housing decision, the lawsuit challenges correctional officers’ response during the actual assault. According to the complaint, correctional officers delayed their intervention when Casio carried out his attack, allowing the violence to escalate unchecked. The lawsuit directly challenges the failure to deploy non-lethal devices or other non-lethal tactical measures that might have prevented further violence before Peterson sustained his most severe injuries. This alleged slow reaction to an ongoing stabbing attack suggests either insufficient training, understaffing, or a troubling disregard for prisoner safety—each possibility reflecting poorly on institutional competence.

The guards’ behaviour during the crucial minutes of the attack raises questions about emergency protocols and personnel readiness within California’s prison system. Conventional correctional practices ordinarily stipulate immediate intervention to violent incidents, yet the lawsuit indicates this incident significantly departed from such protocols. The aggregate consequence of slow response times and the absence of appropriate tactical intervention meant that Peterson’s 16 stab wounds were inflicted with little active opposition from security personnel, changing what could have been a significant event into a life-threatening emergency requiring hospitalisation.

The Wider Context of Lanez’s Incarceration

Tory Lanez’s current imprisonment originates from a widely publicized 2020 shooting incident involving fellow rapper Megan Thee Stallion. The altercation, which occurred during the 2020 summer months, led to Peterson firing at Stallion in the foot. Following a lengthy legal process, he was found guilty in December 2022 on multiple gun-related charges, such as assault using a firearm, and subsequently given a ten-year prison sentence. This conviction represented a major turning point in rap music, drawing extensive press coverage and igniting considerable debate within the music industry regarding accountability and the circumstances surrounding the incident.

Peterson’s legal battles have persisted during his incarceration, with his legal team mounting an appeal contesting the conviction and sentence. However, in November 2025, a three-judge panel rejected his appeal and maintained the 10-year sentence originally imposed, essentially shutting down what many hoped would be an avenue for release or sentence reduction. This denial came approximately six months after the stabbing attack at Tehachapi, meaning Peterson was grappling with both the psychological and physical aftermath of the prison attack whilst simultaneously processing the disappointment of his unsuccessful appeal. The confluence of these events has markedly worsened his situation in the California correctional system.

Legal Actions and Damages Claimed

Tory Lanez’s court action against the California Department of Corrections pursues $100 million in financial restitution, representing one of the most significant claims filed against the state’s correctional system in recent years. The legal action names the Department of Corrections as the principal defendant, alongside the warden and prison staff stationed at the California Correctional Institute in Tehachapi. The lawsuit contends that systemic failures in facility operations and safety measures directly contributed to the seriousness of Peterson’s injuries during the stabbing incident in May 2025. The large compensation amount reflects both the bodily harm sustained and the emotional harm of the unprovoked attack.

At the heart of the lawsuit’s claims is the assertion that correctional officials made a catastrophically poor choice in housing Peterson with cellmate Santino Casio, who was completing a life sentence for second-degree murder. The legal filing asserts that the Department of Corrections either knew or ought to have recognised that this cell assignment posed a serious danger to Peterson, especially given his prominent inmate standing within the prison. Furthermore, the lawsuit challenges the response of security personnel, arguing that guards failed to employ appropriate emergency measures such as stun grenades to halt Casio’s attack. Notably, Casio was never charged with the stabbing despite inflicting 16 injuries on Peterson.

• Department of Corrections failed to prevent identified high-risk inmate pairing
• Celebrity status made Peterson an identifiable target for violence
• Security personnel delayed response to stabbing incident
• Prison failed to employ flash grenades or other containment measures
• Peterson’s belongings, such as unreleased songbooks, are unaccounted for
