Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has filed a $100 million legal action against California’s Department of Corrections following a brutal stabbing attack whilst imprisoned at the California Correctional Institute in Tehachapi in May. The artist, born Daystar Peterson and presently completing a 10-year sentence for the 2020 shooting of Megan Thee Stallion, was stabbed 16 times by fellow inmate Santino Casio in what the lawsuit characterises as an “unprovoked dangerous assault.” The assault left Peterson admitted to hospital with a punctured lung and numerous stabbing injuries 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 delayed response to the violence.

The May 2025 Incident and Its Aftermath

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

Following his recuperation, Peterson was relocated to San Luis Obispo County’s California Men’s Colony, constituting another stage in his time in custody. The lawsuit additionally claims that during this relocation, Peterson did not regain his personal possessions from Tehachapi, including songbooks containing lyrics to unreleased music—a loss that intensifies the psychological and physical harm of the incident. Notably, despite the severity of the attack, Casio was not charged in connection with the assault, a detail the lawsuit underscores as part of systemic shortcomings within the prison service.

• Casio struck Peterson 16 times during the unprovoked assault
• Peterson admitted to hospital with collapsed lung and numerous injuries
• Moved to California Men’s Colony following recovery
• Personal possessions, including songbooks, not recovered from Tehachapi

Accusations of Negligence, and Organisational Breakdown

Accommodation Choices and Security Concerns

At the core of Peterson’s lawsuit lies a fundamental challenge of the Department of Corrections’ decision-making regarding prisoner accommodation placements. The court document argues that housing Peterson alongside Santino Casio—a life-sentence prisoner incarcerated for second-degree murder—constituted a severe breakdown in risk evaluation and prisoner classification. The lawsuit maintains that the department “knew or should have been known” to identify the danger inherent in this pairing. Peterson’s prominent public status, the suit maintains, rendered him an obvious target inside the correctional facility, rendering the accommodation choice not simply negligent but recklessly indifferent to his safety and wellbeing.

The lawsuit underscores that such accommodation determinations require careful consideration of inmate backgrounds, threat levels, and potential motivations for violence. By neglecting to isolate Peterson from Casio, prison administrators purportedly showed a widespread neglect for fundamental security procedures that must oversee California’s detention centres. This failure of duty, the attorneys argues, immediately caused the circumstances in which the stabbing took place, transforming what should have been preventable violence into an wholly predictable consequence of organisational negligence and substandard security arrangements.

Response and Security Behaviour

Beyond the initial housing decision, the lawsuit takes aim at prison guards’ response during the actual assault. According to the filing, correctional officers were slow to intervene when Casio carried out his attack, permitting violence to continue unabated. The lawsuit specifically criticises the failure to employ flash grenades or other non-lethal intervention methods that might have stopped the attack before Peterson suffered his worst injuries. This alleged sluggishness in responding to an active stabbing incident suggests either poor preparation, understaffing, or a troubling indifference to inmate welfare—each possibility undermining institutional competence.

The guards’ behaviour during the critical minutes of the attack raises questions about emergency procedures and staff preparedness within California’s prison system. Conventional correctional practices ordinarily stipulate immediate intervention to acts of violence, yet the lawsuit indicates this incident deviated significantly from such protocols. The combined impact of slow response times and the absence of suitable tactical response meant that Peterson’s 16 stab wounds were inflicted with minimal active resistance from security personnel, transforming what could have been a serious incident into a life-threatening emergency necessitating hospitalisation.

The Larger Context of Lanez’s Confinement

Tory Lanez’s current imprisonment originates from a widely publicized shooting event in 2020 featuring rap artist Megan Thee Stallion. The confrontation, which occurred during the summer of 2020, resulted in Peterson firing at Stallion in the foot. Following a lengthy legal process, he was convicted in December 2022 on several firearms charges, such as assault using a firearm, and subsequently given a ten-year prison sentence. This guilty verdict represented a significant moment in rap music, attracting extensive press coverage and igniting substantial discussion within the music industry concerning responsibility and the events related to the incident.

Peterson’s legal battles have continued throughout his incarceration, with his attorneys mounting an appeal challenging the conviction and sentence. However, in November 2025, a three-judge panel rejected his appeal and maintained the original 10-year sentence, essentially shutting down what many anticipated as an route to freedom or sentence reduction. This denial came approximately six months after the stabbing incident at Tehachapi, meaning Peterson was grappling with both the physical and psychological aftermath of the prison stabbing whilst whilst also processing the disappointment of his unsuccessful appellate challenge. The confluence of these events has significantly complicated his experience within the California correctional system.

Legal Actions and Damages Claimed

Tory Lanez’s court action against the California Department of Corrections pursues $100 million in damages, amounting to one of the most significant cases filed against the state’s correctional system in recent years. The lawsuit 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 correctional management and safety measures directly contributed to the severity of Peterson’s injuries during the 2025 stabbing attack. The large compensation amount reflects both the physical injuries sustained and the psychological impact of the unprovoked attack.

At the heart of the lawsuit’s arguments is the assertion that correctional officials made a dangerously inadequate choice in placing Peterson with fellow inmate Santino Casio, who was completing a life term for murder in the second degree. The legal filing contends that the Department of Corrections either was aware or should have known that this cell assignment posed a serious danger to Peterson, particularly given his prominent inmate standing within the prison. Furthermore, the lawsuit challenges the response of security personnel, contending that guards did not use appropriate emergency measures such as stun grenades to stop Casio’s assault. Notably, Casio was not prosecuted with the assault despite inflicting sixteen wounds on Peterson.

• Celebrity status rendered Peterson a recognisable target for attack
• Security personnel delayed response to stabbing emergency
• Prison did not use flash grenades or other containment measures
