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 severe stabbing incident whilst imprisoned at the California Correctional Institute in Tehachapi in May. The musician, known as Daystar Peterson and currently serving a 10-year prison term 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 assault left Peterson hospitalised with a collapsed lung and numerous stabbing injuries to his back, torso, and head. The lawsuit identifies the Department of Corrections, the facility warden, and guards as respondents, alleging carelessness regarding inmate placement and a delayed response to the violence.

The May 2025 Incident and Its Consequences

The May 2025 stabbing incident at Tehachapi proved 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 several stab injuries across his back, torso, and head—injuries serious enough to warrant immediate hospitalisation. The attack raised significant concerns about security procedures in prisons and inmate classification procedures, particularly given the volatile circumstances of housing two inmates with such markedly different profiles and threat levels.

Following his recuperation, Peterson was transferred to San Luis Obispo County’s California Men’s Colony, constituting another stage in his prison ordeal. The lawsuit further alleges that during this relocation, Peterson failed to retrieve his belongings from Tehachapi, including songbooks containing lyrics to unpublished songs—a loss that intensifies the emotional and physical suffering of the attack. Notably, despite the severity of the attack, Casio was not charged in connection with the stabbing, a detail the lawsuit highlights as part of systemic failures within the prison service.

• Casio struck Peterson 16 times during the unprovoked assault
• Peterson hospitalised with collapsed lung and numerous injuries
• Transferred to California Men’s Colony after recovery
• Personal items, including songbooks, remained missing from Tehachapi

Allegations of Negligence and Institutional Failure

Accommodation Choices and Security Concerns

At the core of Peterson’s lawsuit sits a core challenge of the Department of Corrections’ decision process concerning prisoner accommodation placements. The legal filing contends that housing Peterson with Santino Casio—a lifer serving time for second-degree murder—constituted a catastrophic failure in risk evaluation and prisoner classification. The lawsuit argues that the department “knew or should have been known” to recognise the inherent risk in this arrangement. Peterson’s high-profile celebrity status, the suit maintains, made him an obvious target inside the correctional environment, rendering the accommodation choice not simply negligent but recklessly indifferent to his safety and wellbeing.

The lawsuit emphasises that such accommodation determinations necessitate close examination of inmate backgrounds, risk assessments, and possible drivers for violence. By not segregating Peterson from Casio, correctional officials purportedly showed a institutional indifference for core protective measures that ought to regulate California’s prison system. This breach of care, the attorneys argues, directly precipitated the conditions under which the stabbing happened, changing what could have stayed preventable violence into an entirely foreseeable consequence of systemic failure and substandard security arrangements.

Response and Guard Conduct

Beyond the initial housing decision, the lawsuit targets correctional officers’ response during the incident of violence. According to the complaint, correctional officers delayed their intervention when Casio launched his attack, permitting violence to continue unabated. The lawsuit directly challenges the failure to deploy non-lethal devices or other non-lethal intervention methods that might have halted the assault before Peterson incurred his most critical harm. This alleged slow reaction to an active stabbing incident suggests either poor preparation, inadequate staffing, or a troubling neglect of inmate wellbeing—each possibility casting doubt on institutional competence.

The guards’ actions during the crucial minutes of the attack prompts inquiry into emergency procedures and personnel readiness within California’s prison system. Conventional correctional practices generally require swift action to violent incidents, yet the lawsuit suggests this incident deviated significantly from such protocols. The combined impact 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, transforming what could have been a significant event into a life-threatening situation demanding hospital treatment.

The Wider Context of Lanez’s Confinement

Tory Lanez’s current imprisonment originates from a high-profile 2020 shooting incident featuring fellow rapper Megan Thee Stallion. The altercation, which took place in the 2020 summer months, led to Peterson firing at Stallion in her foot. After a prolonged court proceedings, he was convicted 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, attracting widespread media attention and sparking substantial discussion across the music sector regarding responsibility and the circumstances surrounding the incident.

Peterson’s ongoing litigation have persisted during his incarceration, with his attorneys filing an appeal contesting the conviction and sentence. However, in November 2025, a three-judge panel denied his appeal and upheld the 10-year sentence originally imposed, essentially shutting down what many anticipated as an path to release or sentence reduction. This rejection came roughly six months after the stabbing attack at Tehachapi, meaning Peterson was contending with both the physical and psychological aftermath of the prison stabbing whilst whilst also processing the frustration of his failed appellate challenge. The convergence of these circumstances has substantially complicated his situation in the California prison system.

Lawful Claims and Compensation Requested

Tory Lanez’s court action against the California Department of Corrections seeks $100 million in financial restitution, constituting 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, together with the warden and correctional officers stationed at the California Correctional Institute in Tehachapi. The lawsuit argues that institutional failures in facility operations and safety measures resulted in the severity of Peterson’s injuries during the stabbing incident in May 2025. The substantial compensation figure reflects both the bodily harm 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 housing Peterson with cellmate Santino Casio, who was serving a life sentence for second-degree murder. The court documents asserts that the Department of Corrections either was aware or should have known that this housing arrangement posed a significant risk to Peterson, particularly given his high-profile celebrity standing within the prison. Furthermore, the lawsuit challenges the actions of correctional staff, arguing that guards failed to employ proper emergency procedures such as flash grenades to stop Casio’s assault. Notably, Casio was never charged with the stabbing despite causing 16 injuries on Peterson.

• Correctional Department failed to prevent identified high-risk inmate pairing
• Celebrity status rendered Peterson an identifiable target for attack
• Security personnel were slow to respond to stabbing incident
• Prison did not use flash grenades or alternative security measures
• Peterson’s belongings, including unreleased songbooks, are unaccounted for
