Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has filed a $100 million lawsuit against California’s Department of Corrections following a brutal stabbing attack whilst incarcerated at the California Correctional Institute in Tehachapi last May. The artist, known as 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 fellow inmate Santino Casio in what the lawsuit describes as an “unprovoked life-threatening attack.” The attack left Peterson hospitalised with a punctured lung and multiple stab wounds to his back, torso, and head. The lawsuit identifies the Department of Corrections, the prison warden, and guards as respondents, alleging carelessness regarding inmate placement 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 attack that left the rapper struggling to survive. Peterson sustained a punctured 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 classification systems for inmates, particularly given the dangerous situation of housing two inmates with such starkly different profiles and threat levels.

Following his recovery, Peterson was relocated to San Luis Obispo County’s California Men’s Colony, representing another phase in his time in custody. The lawsuit further alleges that during this move, Peterson did not regain his personal possessions from Tehachapi, including songbooks featuring lyrics to unpublished songs—a loss that exacerbates the physical and emotional trauma of the assault. Notably, despite the seriousness of the assault, Casio was not prosecuted in connection with the knife attack, a detail the lawsuit underscores as part of systemic shortcomings within the prison service.

• Casio struck Peterson 16 times during the unprovoked attack
• Peterson hospitalised with punctured lung and numerous injuries
• Relocated to California Men’s Colony after recovery
• Personal possessions, including songbooks, not recovered from Tehachapi

Accusations of Negligence and Institutional Failure

Accommodation Choices and Safety Issues

At the heart of Peterson’s lawsuit sits a fundamental challenge of the Corrections Department’s decision process regarding prisoner accommodation placements. The court document contends that placing Peterson alongside Santino Casio—a lifer incarcerated for second-degree murder—represented a severe breakdown in risk assessment and inmate classification. The lawsuit argues that the department “knew or should have been known” to identify the danger inherent in this pairing. Peterson’s high-profile celebrity status, the suit maintains, made him an clear target within the prison facility, rendering 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, threat levels, and underlying reasons for violence. By neglecting to isolate Peterson from Casio, prison administrators reportedly displayed a widespread neglect for fundamental security procedures that should govern California’s detention centres. This failure of duty, the legal team contends, directly precipitated the circumstances in which the stabbing happened, transforming what should have been preventable violence into an completely anticipated consequence of organisational negligence and insufficient safety provisions.

Response and Security Conduct

Beyond the initial housing decision, the lawsuit takes aim at correctional officers’ response during the actual assault. According to the filing, correctional officers failed to act promptly when Casio carried out his attack, enabling the situation to worsen. The lawsuit explicitly condemns the failure to employ flash grenades or other non-lethal intervention methods that might have halted the assault before Peterson incurred his most critical harm. This alleged sluggishness in responding to an active stabbing incident suggests either poor preparation, understaffing, or a troubling indifference to inmate welfare—each possibility casting doubt on institutional competence.

The guards’ actions during the critical minutes of the attack calls into question emergency protocols and personnel readiness within California’s prison system. Conventional correctional practices generally require swift action to acts of violence, yet the lawsuit indicates this incident deviated significantly from such protocols. The aggregate consequence 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 significant event into a critical emergency requiring hospitalisation.

The Wider Context of Lanez’s Confinement

Tory Lanez’s current imprisonment stems from a widely publicized shooting event in 2020 involving rap artist Megan Thee Stallion. The confrontation, which took place in the 2020 summer months, resulted in Peterson shooting Stallion in the foot. Following a prolonged court proceedings, he was found guilty in December 2022 on multiple gun-related charges, including assault using a firearm, and thereafter sentenced to a ten-year prison sentence. This conviction marked a significant moment in rap music, drawing extensive press coverage and sparking substantial discussion across the music sector regarding responsibility and the events related to the occurrence.

Peterson’s ongoing litigation have persisted during his incarceration, with his attorneys mounting an appeal challenging the conviction and sentence. However, in November 2025, a panel of three judges denied his appeal and maintained the original 10-year sentence, effectively closing what many hoped would be 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 psychological and physical aftermath of the prison stabbing whilst simultaneously processing the disappointment of his failed appellate challenge. The convergence of these circumstances has significantly complicated his experience within the California prison system.

Legal Claims and Damages Claimed

Tory Lanez’s court action against the California Department of Corrections seeks $100 million in damages, representing one of the most substantial cases filed against the state’s correctional system in recent times. The legal action names the Department of Corrections as the principal defendant, alongside the warden and correctional officers stationed at the California Correctional Institute in Tehachapi. The lawsuit contends that widespread deficiencies in prison management and safety measures directly contributed to the seriousness of Peterson’s injuries during the 2025 stabbing attack. The significant financial award reflects both the bodily harm sustained and the mental distress of the unprovoked incident.

Central to the lawsuit’s claims is the assertion that correctional officials made a catastrophically poor choice in placing Peterson with fellow inmate Santino Casio, who was completing a life term for second-degree murder. The court documents asserts that the correctional department either knew or should have known that this housing arrangement posed a serious danger to Peterson, particularly given his high-profile celebrity standing within the facility. Furthermore, the lawsuit challenges the actions of correctional staff, contending that guards failed to employ proper emergency procedures such as flash grenades to halt Casio’s attack. Notably, Casio was not prosecuted with the stabbing despite inflicting sixteen wounds on Peterson.

• Department of Corrections failed to prevent known dangerous inmate pairing
• Celebrity status made Peterson a recognisable target for attack
• Security personnel delayed response to stabbing incident
• Prison failed to employ flash grenades or other containment measures
• Peterson’s personal possessions, such as unreleased songbooks, remain missing
