Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has launched a $100 million legal action 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 currently serving a 10-year sentence for the 2020 shooting of 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 names the Department of Corrections, the facility 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 represented a watershed moment in Peterson’s incarceration. According to the lawsuit, fellow inmate Santino Casio, who was serving a life sentence for second-degree murder, launched an unprovoked attack that left the rapper fighting for his life. 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 serious questions about prison security protocols and inmate classification procedures, particularly given the volatile circumstances of housing two inmates with such starkly different profiles and threat levels.

Following his recuperation, Peterson was moved to San Luis Obispo County’s California Men’s Colony, marking another chapter in his prison ordeal. The lawsuit further contends that during this relocation, Peterson failed to retrieve his belongings from Tehachapi, including songbooks with lyrics to unreleased compositions—a loss that exacerbates the psychological and physical harm of the incident. Notably, despite the gravity of the incident, Casio was not held accountable in connection with the stabbing, a detail the lawsuit highlights as part of systemic shortcomings within the prison service.

• Casio stabbed Peterson 16 times during the unprovoked incident
• Peterson hospitalised with punctured lung and several lacerations
• Moved to California Men’s Colony upon recovery
• Personal possessions, including songbooks, not recovered from Tehachapi

Claims of Negligence and Institutional Failure

Accommodation Choices and Security Worries

At the core of Peterson’s lawsuit lies a fundamental challenge of the Department of Corrections’ decision process concerning prisoner accommodation placements. The legal filing contends that placing Peterson with Santino Casio—a life-sentence prisoner incarcerated for second-degree murder—represented a severe breakdown in risk assessment and prisoner classification. The lawsuit maintains that the department “ought to have been aware” to identify the inherent risk in this arrangement. Peterson’s prominent public status, the suit maintains, made him an obvious target within the prison facility, rendering the housing decision not simply negligent but callously indifferent to his safety and wellbeing.

The lawsuit highlights that such accommodation determinations require careful consideration of detainee profiles, security classifications, and possible drivers for violence. By neglecting to isolate Peterson from Casio, facility management allegedly demonstrated a institutional indifference for core protective measures that should govern California’s detention centres. This negligence, the legal team contends, directly precipitated the environment where the stabbing occurred, changing what could have stayed preventable violence into an entirely foreseeable consequence of organisational negligence and substandard security arrangements.

Response and Security Behaviour

Beyond the initial housing decision, the lawsuit targets correctional officers’ response during the actual assault. According to the complaint, correctional officers were slow to intervene when Casio launched his attack, permitting violence to continue unabated. The lawsuit specifically criticises the failure to employ flash grenades or other non-lethal tactical measures that might have halted the assault before Peterson incurred his most critical harm. This alleged slow reaction to an ongoing stabbing attack suggests either insufficient training, inadequate staffing, or a troubling disregard for prisoner safety—each possibility undermining institutional competence.

The guards’ actions during the crucial minutes of the attack raises questions about emergency protocols and personnel readiness within California’s prison system. Typical prison protocols ordinarily stipulate rapid response to acts of violence, yet the lawsuit indicates this incident deviated significantly from such protocols. The combined impact of slow response times and the absence of suitable tactical response meant that Peterson’s 16 stab wounds were inflicted with scant active defence from security personnel, converting what could have been a serious incident into a life-threatening emergency requiring hospitalisation.

The Wider Context of Lanez’s Confinement

Tory Lanez’s ongoing incarceration originates from a widely publicized 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 her foot. After a prolonged court proceedings, he was convicted in December 2022 on several firearms charges, including assault with a firearm, and subsequently sentenced to a decade in prison. This conviction represented a major turning point in rap music, drawing widespread media attention and igniting substantial discussion within the music industry concerning responsibility and the events related to the occurrence.

Peterson’s ongoing litigation 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 denied 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 about six months after the stabbing attack at Tehachapi, meaning Peterson was grappling with both the psychological and physical aftermath of the prison attack whilst whilst also processing the frustration of his failed appellate challenge. The combination of these events has markedly worsened his circumstances within the California prison system.

Legal Actions and Damages Claimed

Tory Lanez’s court action against the California Department of Corrections pursues $100 million in compensation, constituting one of the most substantial suits filed against the state’s correctional system in recent years. The legal action names the Department of Corrections as the primary defendant, in addition to the warden and correctional officers stationed at the California Correctional Institute in Tehachapi. The lawsuit contends that systemic failures in facility operations and security protocols resulted in the severity of Peterson’s injuries during the 2025 stabbing attack. The substantial compensation figure reflects both the physical injuries sustained and the psychological impact of the unprovoked attack.

Central to the lawsuit’s arguments is the allegation that prison authorities made a dangerously inadequate choice in placing Peterson with fellow inmate Santino Casio, who was serving a life sentence for second-degree murder. The legal filing contends that the Department of Corrections either knew or ought to have recognised that this housing arrangement posed a significant risk to Peterson, especially given his high-profile celebrity standing within the prison. Furthermore, the lawsuit challenges the response of correctional staff, contending that officers did not use appropriate emergency measures such as flash grenades to stop Casio’s attack. Notably, Casio was never charged with the stabbing despite causing 16 injuries on Peterson.

• Department of Corrections failed to prevent identified high-risk inmate pairing
• Celebrity status made Peterson an identifiable target for attack
• Security personnel delayed response to stabbing incident
• Prison failed to employ flash grenades or other containment measures
• Peterson’s personal possessions, including unreleased songbooks, remain missing
