Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has launched a $100 million legal action against California’s Department of Corrections after a severe stabbing incident whilst incarcerated 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 of 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 attack 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 respondents, alleging carelessness regarding inmate placement and a slow reaction 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 serving a life sentence for murder in the second degree, launched an unprovoked assault that left the rapper struggling to survive. 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 serious questions about prison security protocols and inmate classification procedures, particularly given the volatile circumstances of housing two inmates with such markedly different profiles and threat levels.

Following his return to health, Peterson was moved to San Luis Obispo County’s California Men’s Colony, marking another chapter in his incarceration experience. The lawsuit additionally claims that during this relocation, Peterson never recovered his personal possessions from Tehachapi, including songbooks containing lyrics to unpublished songs—a loss that intensifies the physical and emotional trauma of the incident. Notably, despite the severity of the attack, Casio was not held accountable in connection with the stabbing, a detail the lawsuit highlights as part of systemic failures within the correctional system.

• Casio attacked Peterson 16 times during the unprovoked attack
• Peterson hospitalised with punctured lung and multiple wounds
• Relocated to California Men’s Colony following recovery
• Personal possessions, including songbooks, never recovered from Tehachapi

Allegations of Negligence, and Systemic Failure

Housing Decisions and Security Worries

At the core of Peterson’s lawsuit sits a fundamental challenge of the Department of Corrections’ decision-making concerning inmate housing assignments. The court document contends that placing Peterson alongside Santino Casio—a lifer incarcerated for second-degree murder—represented a severe breakdown in risk evaluation and inmate classification. The lawsuit argues that the department “ought to have been aware” to identify the inherent risk in this pairing. Peterson’s high-profile celebrity status, the suit maintains, made him an clear target inside the correctional facility, making the accommodation choice not merely negligent but callously indifferent to his safety and wellbeing.

The lawsuit emphasises that such accommodation determinations require careful consideration of detainee profiles, threat levels, and possible drivers for violence. By not segregating Peterson from Casio, prison administrators purportedly showed a systemic disregard for core protective measures that ought to regulate California’s prison system. This breach of care, the counsel maintains, immediately caused the circumstances in which the stabbing took place, transforming what should have been preventable violence into an entirely foreseeable consequence of systemic failure and insufficient safety provisions.

Response and Security Conduct

Beyond the primary accommodation decision, the lawsuit takes aim at prison guards’ response during the actual assault. According to the filing, correctional officers delayed their intervention when Casio launched his attack, permitting violence to continue unabated. The lawsuit directly challenges the failure to employ flash grenades or other non-lethal intervention methods that might have halted the assault before Peterson sustained his most severe injuries. This alleged slow reaction to an active stabbing incident suggests either insufficient training, insufficient staffing, or a troubling indifference to inmate welfare—each possibility casting doubt on institutional competence.

The guards’ conduct during the critical minutes of the attack raises questions about emergency procedures and personnel readiness within California’s prison system. Conventional correctional practices ordinarily stipulate rapid response to acts of violence, yet the lawsuit suggests this incident significantly departed from such protocols. The cumulative effect of delayed responses and the lack of suitable tactical response meant that Peterson’s 16 stab wounds were inflicted with minimal active resistance from security personnel, changing what could have been a significant event into a life-threatening emergency necessitating hospitalisation.

The Wider Context of Lanez’s Imprisonment

Tory Lanez’s current imprisonment originates from a high-profile 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. After a lengthy legal process, he was convicted in December 2022 on several firearms charges, such as assault with a firearm, and subsequently sentenced to a ten-year prison sentence. This guilty verdict represented a major turning point in rap music, attracting extensive press coverage and sparking substantial discussion within the music industry regarding responsibility and the circumstances surrounding the incident.

Peterson’s legal battles have persisted during his incarceration, with his defence counsel lodging an appeal contesting the conviction and sentence. However, in November 2025, a three-judge panel rejected his appeal and upheld the original 10-year sentence, essentially shutting down what many anticipated as an route to freedom or sentence reduction. 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 unsuccessful appellate challenge. The combination of these events has significantly complicated his experience within the California prison system.

Legal Actions and Damages Claimed

Tory Lanez’s lawsuit against the California Department of Corrections seeks $100 million in financial restitution, amounting to one of the most substantial cases filed against the state’s correctional system in the past several years. The lawsuit names the Department of Corrections as the main defendant, together with the warden and correctional officers stationed at the California Correctional Institute in Tehachapi. The lawsuit contends that institutional failures in correctional management and security procedures directly contributed to the seriousness of Peterson’s injuries during the 2025 stabbing attack. The large compensation amount reflects both the physical trauma sustained and the psychological impact of the unprovoked incident.

At the heart of the lawsuit’s claims is the allegation that correctional officials made a catastrophically poor choice in housing Peterson with fellow inmate Santino Casio, who was serving a life sentence for second-degree murder. The court documents asserts that the correctional department either knew or should have known that this cell assignment posed a serious danger to Peterson, particularly 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 stop Casio’s assault. Notably, Casio was not prosecuted with the stabbing despite causing sixteen wounds on Peterson.
