Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has filed a $100 million lawsuit against California’s Department of Corrections after a severe stabbing incident whilst imprisoned at the California Correctional Institute in Tehachapi last May. The musician, known as Daystar Peterson and currently serving 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 dangerous assault.” The assault left Peterson admitted to hospital 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 defendants, alleging negligence in housing decisions and a slow reaction to the violence.

The May 2025 Attack and Its Consequences

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 completing a life sentence for second-degree murder, launched an unprovoked attack that left the rapper fighting for his life. 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 moved to San Luis Obispo County’s California Men’s Colony, representing another phase in his prison ordeal. The lawsuit additionally claims that during this transfer, Peterson never recovered his personal items from Tehachapi, including songbooks featuring lyrics to unpublished songs—a loss that exacerbates the emotional and physical suffering of the assault. Notably, despite the severity of the attack, Casio was not prosecuted in connection with the stabbing, a detail the lawsuit underscores as part of institutional breakdowns within the prison service.

Claims of Negligence and Institutional Failure

Accommodation Choices and Security Concerns

At the core of Peterson’s lawsuit lies a fundamental challenge of the Department of Corrections’ decision-making regarding inmate housing assignments. The legal filing contends that placing Peterson alongside Santino Casio—a lifer serving time for murder in the second degree—constituted a catastrophic failure in risk evaluation and prisoner classification. The lawsuit argues that the department “ought to have been aware” to recognise the danger inherent in this arrangement. Peterson’s prominent public status, the suit maintains, rendered him an obvious target inside the correctional facility, rendering the housing decision not merely negligent but recklessly indifferent to his safety and wellbeing.

The lawsuit highlights that such housing decisions demand thorough evaluation of prisoner histories, threat levels, and possible drivers for violence. By failing to separate Peterson from Casio, facility management purportedly showed a institutional indifference for fundamental security procedures that ought to regulate California’s correctional facilities. This breach of care, the legal team contends, immediately caused the conditions under which the stabbing occurred, changing what could have stayed preventable violence into an entirely foreseeable consequence of organisational negligence and inadequate protective measures.

Response and Guard Behaviour

Beyond the primary accommodation decision, the lawsuit targets prison guards’ response during the incident of violence. According to the filing, correctional officers failed to act promptly when Casio launched his attack, enabling the situation to worsen. The lawsuit specifically criticises the failure to use flash grenades or other non-lethal intervention methods that might have prevented further violence before Peterson sustained his most severe injuries. This alleged delay in response to an ongoing stabbing attack suggests either inadequate training, understaffing, or a troubling indifference to inmate welfare—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. Standard correctional procedures typically mandate swift action to violent incidents, yet the lawsuit contends this incident deviated significantly from such protocols. The cumulative effect of sluggish reaction times and the failure to implement 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 grave occurrence into a critical emergency requiring hospitalisation.

The Larger Context of Lanez’s Incarceration

Tory Lanez’s current imprisonment originates from a widely publicized 2020 shooting incident featuring fellow rapper Megan Thee Stallion. The confrontation, which took place in the summer of 2020, resulted in Peterson shooting Stallion in the foot. Following a prolonged court proceedings, he was convicted in December 2022 on multiple gun-related charges, including assault with a firearm, and subsequently given a ten-year prison sentence. This conviction represented a major turning point in hip-hop, drawing widespread media attention and sparking substantial discussion across the music sector concerning accountability and the circumstances surrounding the incident.

Peterson’s ongoing litigation have persisted during his incarceration, with his attorneys lodging an appeal challenging the conviction and sentence. However, in November 2025, a panel of three judges rejected his appeal and maintained the original 10-year sentence, effectively closing what many hoped would be an avenue for release or sentence reduction. This rejection came about six months after the stabbing attack at Tehachapi, meaning Peterson was dealing with both the physical and psychological aftermath of the prison stabbing whilst at the same time dealing with the disappointment of his unsuccessful appellate challenge. The combination of these events has significantly complicated his situation in the California correctional system.

Legal Claims and Compensation Sought

Tory Lanez’s legal claim against the California Department of Corrections demands $100 million in damages, amounting to one of the most significant suits filed against the state’s correctional system in recent times. The lawsuit names the Department of Corrections as the principal defendant, together with the warden and correctional officers stationed at the California Correctional Institute in Tehachapi. The lawsuit asserts that systemic failures in facility operations and security protocols directly contributed to the extent of Peterson’s injuries during the May 2025 stabbing incident. The substantial compensation figure reflects both the physical injuries sustained and the emotional harm of the unprovoked assault.

Central to the lawsuit’s claims is the assertion that prison authorities made a catastrophically poor decision in placing Peterson with fellow inmate Santino Casio, who was completing a life sentence for murder in the second degree. The legal filing asserts that the Department of Corrections either knew 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 criticises the response of security personnel, contending that officers did not use proper emergency procedures such as stun grenades to stop Casio’s attack. Notably, Casio was never charged with the assault despite inflicting sixteen wounds on Peterson.
