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 brutal stabbing attack whilst incarcerated at the California Correctional Institute in Tehachapi in May. The artist, born Daystar Peterson and presently completing 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 characterises as an “unprovoked dangerous assault.” The assault left Peterson hospitalised with a collapsed 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 negligence in housing decisions and a slow reaction 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 multiple stab wounds across his back, torso, and head—injuries severe enough to warrant emergency 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 return to health, Peterson was relocated to San Luis Obispo County’s California Men’s Colony, representing another phase in his time in custody. The lawsuit further contends that during this transfer, Peterson never recovered his belongings from Tehachapi, including songbooks containing lyrics to unreleased music—a loss that exacerbates the emotional and physical suffering of the attack. Notably, despite the gravity of the incident, Casio was not prosecuted in connection with the stabbing, a detail the lawsuit emphasises as part of institutional breakdowns within the Department of Corrections.

• Casio attacked Peterson 16 times during the unprovoked incident
• Peterson admitted to hospital with collapsed lung and several lacerations
• Moved to California Men’s Colony upon recovery
• Personal belongings, including songbooks, never recovered from Tehachapi

Accusations of Negligence, and Institutional Failure

Housing Options and Security Concerns

At the core of Peterson’s lawsuit lies a fundamental criticism of the Department of Corrections’ decision process regarding inmate housing assignments. The legal filing contends that housing Peterson alongside Santino Casio—a life-sentence prisoner incarcerated for second-degree murder—constituted a severe breakdown in risk evaluation and inmate classification. The lawsuit argues that the department “ought to have been aware” to identify the danger inherent in this arrangement. Peterson’s high-profile celebrity status, the suit maintains, rendered him an clear target within the prison facility, making the accommodation choice not simply negligent but recklessly indifferent to his safety and wellbeing.

The lawsuit underscores that such placement choices demand thorough evaluation of prisoner histories, security classifications, and possible drivers for violence. By failing to separate Peterson from Casio, correctional officials allegedly demonstrated a widespread neglect for basic safety protocols that must oversee California’s correctional facilities. This negligence, the attorneys maintains, substantially contributed to the environment where the stabbing happened, converting what might have remained preventable violence into an completely anticipated 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 complaint, correctional officers failed to act promptly when Casio initiated the assault, allowing the violence to escalate unchecked. The lawsuit specifically criticises the failure to use flash grenades or other non-lethal intervention methods that might have halted the assault before Peterson suffered his worst injuries. This alleged sluggishness in responding to an active stabbing incident suggests either poor preparation, understaffing, or a troubling disregard for prisoner safety—each possibility undermining institutional competence.

The guards’ conduct during the crucial minutes of the attack prompts inquiry into emergency procedures and staff preparedness within California’s prison system. Conventional correctional practices typically mandate swift action to violent incidents, yet the lawsuit suggests this incident departed substantially from such protocols. The combined impact of slow response times and the failure to implement proper tactical measures meant that Peterson’s 16 stab wounds were inflicted with minimal active resistance from security personnel, converting what could have been a serious incident into a life-threatening emergency demanding hospital treatment.

The Larger Context of Lanez’s Imprisonment

Tory Lanez’s ongoing incarceration stems from a widely publicized 2020 shooting incident featuring rap artist Megan Thee Stallion. The altercation, which took place in the 2020 summer months, led to Peterson shooting Stallion in the foot. Following a prolonged court proceedings, he was convicted in December 2022 on multiple gun-related charges, such as assault with a firearm, and thereafter given a ten-year prison sentence. This conviction marked a significant moment in rap music, drawing widespread media attention and igniting considerable debate across the music sector concerning responsibility and the events related to the incident.

Peterson’s ongoing litigation have continued throughout his incarceration, with his attorneys mounting an appeal contesting the conviction and sentence. However, in November 2025, a panel of three judges rejected his appeal and upheld the 10-year sentence originally imposed, essentially shutting down what many hoped would be an path to release or sentence reduction. This denial came approximately six months after the stabbing incident at Tehachapi, meaning Peterson was contending with both the physical and psychological aftermath of the prison stabbing whilst simultaneously processing the frustration of his failed appellate challenge. The confluence of these events has markedly worsened his situation in the California correctional system.

Legal Actions and Compensation Requested

Tory Lanez’s court action against the California Department of Corrections demands $100 million in compensation, amounting to one of the most substantial cases filed against the state’s correctional system in recent years. The lawsuit names the Department of Corrections as the primary defendant, together with the warden and correctional officers stationed at the California Correctional Institute in Tehachapi. The lawsuit asserts that institutional failures in correctional management and safety measures led to the seriousness of Peterson’s injuries during the 2025 stabbing attack. The large compensation amount reflects both the bodily harm sustained and the emotional harm of the unprovoked assault.

At the heart of the lawsuit’s claims is the allegation that prison authorities made a dangerously inadequate decision in placing Peterson with cellmate Santino Casio, who was serving a life term for murder in the second degree. The legal filing contends that the Department of Corrections either knew or ought to have recognised that this housing arrangement posed a serious danger to Peterson, especially given his high-profile celebrity status within the facility. Furthermore, the lawsuit challenges the actions of security personnel, arguing that officers did not use proper emergency procedures such as flash grenades to stop Casio’s attack. Notably, Casio was never charged with the assault despite inflicting 16 injuries on Peterson.
