Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has launched a $100 million lawsuit against California’s Department of Corrections following a severe stabbing incident whilst incarcerated at the California Correctional Institute in Tehachapi in May. The artist, born 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 prison inmate Santino Casio in what the lawsuit characterises as an “unprovoked dangerous assault.” The assault 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 prison warden, and guards as defendants, alleging carelessness regarding inmate placement and a slow reaction to the violence.

The May 2025 Attack 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 fighting for his life. Peterson sustained a collapsed lung alongside several stab injuries 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 recuperation, 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 failed to retrieve his personal possessions from Tehachapi, including songbooks containing lyrics to unreleased music—a loss that intensifies the emotional and physical suffering of the assault. Notably, despite the gravity of the incident, Casio was not charged in connection with the knife attack, a detail the lawsuit underscores as part of systemic failures within the correctional system.

• Casio stabbed Peterson 16 times during the unprovoked attack
• Peterson taken to hospital with collapsed lung and several lacerations
• Relocated to California Men’s Colony following recovery
• Personal items, including songbooks, not recovered from Tehachapi

Claims of Negligence and Institutional Failure

Housing Options and Security Worries

At the core of Peterson’s lawsuit lies a core criticism of the Department of Corrections’ decision-making concerning inmate housing assignments. The court document contends that housing Peterson alongside Santino Casio—a lifer serving time for second-degree murder—constituted a catastrophic failure in risk evaluation and inmate classification. The lawsuit argues that the department “ought to have been aware” to identify the inherent risk in this arrangement. Peterson’s high-profile celebrity profile, the suit contends, made him an obvious target inside the correctional environment, rendering the accommodation choice not simply negligent but callously indifferent to his wellbeing and safety.

The lawsuit emphasises that such housing decisions require careful consideration of prisoner histories, risk assessments, and underlying reasons for violence. By neglecting to isolate Peterson from Casio, correctional officials reportedly displayed a widespread neglect for core protective measures that should govern California’s detention centres. This failure of duty, the attorneys argues, substantially contributed to the conditions under which the stabbing happened, transforming what should have been preventable violence into an completely anticipated consequence of institutional mismanagement and inadequate protective measures.

Response and Security Conduct

Beyond the initial housing decision, the lawsuit takes aim at prison guards’ response during the incident of violence. According to the complaint, correctional officers delayed their intervention when Casio initiated the assault, enabling the situation to worsen. The lawsuit specifically criticises the failure to use flash grenades or other non-lethal tactical measures that might have stopped the attack before Peterson sustained his most severe injuries. This alleged sluggishness in responding to an active stabbing incident suggests either poor preparation, insufficient staffing, or a troubling neglect of inmate wellbeing—each possibility reflecting poorly on institutional competence.

The guards’ conduct during the crucial minutes of the attack raises questions about emergency procedures and staff preparedness within California’s prison system. Typical prison protocols typically mandate immediate intervention to acts of violence, yet the lawsuit suggests this incident deviated significantly from such protocols. The aggregate consequence of slow response times and the lack of appropriate tactical intervention meant that Peterson’s 16 stab wounds were inflicted with scant active defence from security personnel, transforming what could have been a grave occurrence into a life-threatening emergency demanding hospital treatment.

The Larger Context of Lanez’s Confinement

Tory Lanez’s current imprisonment originates from a high-profile shooting event in 2020 involving rap artist Megan Thee Stallion. The altercation, which occurred during the summer of 2020, resulted in Peterson firing at Stallion in the foot. After a prolonged court proceedings, he was found guilty in December 2022 on several firearms charges, including assault using a firearm, and subsequently given a decade in prison. This guilty verdict represented a major turning point in rap music, attracting extensive press coverage and igniting considerable debate within the music industry concerning responsibility and the circumstances surrounding the occurrence.

Peterson’s legal battles have continued throughout 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 10-year sentence originally imposed, essentially shutting down what many hoped would be an route to freedom or reduction in sentence. This denial came roughly six months after the stabbing incident at Tehachapi, meaning Peterson was contending with both the psychological and physical aftermath of the prison attack whilst simultaneously processing the disappointment of his unsuccessful appeal. The combination of these events has significantly complicated his circumstances within the California correctional system.

Lawful Claims and Compensation Sought

Tory Lanez’s court action against the California Department of Corrections demands $100 million in financial restitution, constituting one of the largest claims filed against the state’s correctional system in the past several years. The lawsuit names the Department of Corrections as the principal defendant, alongside the warden and prison staff stationed at the California Correctional Institute in Tehachapi. The lawsuit argues that institutional failures in prison management and security protocols directly contributed to the seriousness of Peterson’s injuries during the stabbing incident in May 2025. The significant financial award reflects both the bodily harm sustained and the mental distress of the unprovoked attack.

Central to the lawsuit’s arguments is the allegation that prison authorities made a dangerously inadequate choice in housing Peterson with cellmate 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 ought to have recognised that this housing arrangement posed a serious danger to Peterson, particularly given his prominent inmate status within the facility. Furthermore, the lawsuit criticises the actions of security personnel, arguing that guards failed to employ appropriate emergency measures such as stun grenades to stop Casio’s assault. Notably, Casio was never charged with the stabbing despite causing 16 injuries on Peterson.

• Department of Corrections failed to prevent known dangerous inmate pairing
• Celebrity status made Peterson an identifiable target for attack
• Security personnel were slow to respond to stabbing incident
• Prison failed to employ flash grenades or alternative security measures
• Peterson’s personal possessions, such as unreleased songbooks, are unaccounted for
