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 brutal stabbing attack whilst incarcerated at the California Correctional Institute in Tehachapi in May. The musician, born Daystar Peterson and currently serving 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 life-threatening attack.” The attack left Peterson admitted to hospital 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 delayed response 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 murder in the second degree, launched an unprovoked assault that left the rapper struggling to survive. Peterson sustained a punctured lung alongside multiple stab wounds across his back, torso, and head—injuries serious enough to warrant emergency hospitalisation. The attack raised serious questions about security procedures in prisons and inmate classification procedures, particularly given the dangerous situation 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, constituting another stage in his prison ordeal. The lawsuit further alleges that during this transfer, Peterson did not regain his personal possessions from Tehachapi, including songbooks containing lyrics to unreleased music—a loss that compounds the physical and emotional trauma of the assault. Notably, despite the gravity of the incident, Casio was not prosecuted in connection with the assault, a detail the lawsuit emphasises as part of systemic failures within the prison service.

• Casio struck Peterson 16 times during the unprovoked assault
• Peterson admitted to hospital with collapsed lung and multiple wounds
• Moved to California Men’s Colony upon recovery
• Personal items, including songbooks, not recovered from Tehachapi

Accusations of Negligence, and Systemic Failure

Housing Decisions and Safety Issues

At the core of Peterson’s lawsuit lies a fundamental challenge of the Corrections Department’s decision process concerning prisoner accommodation placements. The court document contends that housing Peterson with Santino Casio—a lifer serving time for second-degree murder—represented a severe breakdown in risk evaluation and inmate classification. The lawsuit maintains 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 clear target inside the correctional facility, rendering the housing decision not merely negligent but callously indifferent to his safety and wellbeing.

The lawsuit highlights that such accommodation determinations require careful consideration of prisoner histories, risk assessments, and potential motivations for violence. By not segregating Peterson from Casio, prison administrators reportedly displayed a systemic disregard for core protective measures that should govern California’s correctional facilities. This breach of care, the legal team argues, substantially contributed to the circumstances in which the stabbing happened, changing what could have stayed preventable violence into an entirely foreseeable consequence of organisational negligence and insufficient safety provisions.

Response and Guard Conduct

Beyond the primary accommodation decision, the lawsuit targets prison guards’ response during the actual assault. According to the filing, correctional officers were slow to intervene when Casio carried out his attack, allowing the violence to escalate unchecked. The lawsuit specifically criticises the failure to deploy non-lethal devices or other non-lethal intervention methods that might have halted the assault before Peterson sustained his most severe injuries. This alleged sluggishness in responding to an active stabbing incident suggests either insufficient 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 procedures and staff preparedness within California’s prison system. Conventional correctional practices ordinarily stipulate rapid response to violent incidents, yet the lawsuit suggests this incident departed substantially from such protocols. The aggregate consequence of sluggish reaction times and the absence of proper tactical measures meant that Peterson’s 16 stab wounds were inflicted with little active opposition from security personnel, transforming what could have been a significant event into a life-threatening situation demanding hospital treatment.

The Expanded Context of Lanez’s Incarceration

Tory Lanez’s current imprisonment stems from a high-profile 2020 shooting incident involving rap artist Megan Thee Stallion. The altercation, which took place in the summer of 2020, led to Peterson firing at Stallion in her foot. After a lengthy legal process, he was found guilty in December 2022 on several firearms charges, including assault using a firearm, and thereafter given a ten-year prison sentence. This conviction marked a major turning point in rap music, attracting widespread media attention and igniting considerable debate within the music industry regarding responsibility and the circumstances surrounding the occurrence.

Peterson’s court disputes have persisted during his incarceration, with his attorneys mounting an appeal challenging the conviction and sentence. However, in November 2025, a three-judge panel denied his appeal and maintained 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 grappling with both the psychological and physical aftermath of the prison attack whilst simultaneously processing the disappointment of his failed appellate challenge. The convergence of these circumstances has markedly worsened his circumstances within the California prison system.

Legal Claims and Compensation Requested

Tory Lanez’s legal claim against the California Department of Corrections demands $100 million in financial restitution, representing one of the largest suits filed against the state’s correctional system in the past several years. The legal action names the Department of Corrections as the primary defendant, together with the warden and individual guards stationed at the California Correctional Institute in Tehachapi. The lawsuit contends that institutional failures in correctional management and security protocols resulted in the extent of Peterson’s injuries during the stabbing incident in May 2025. The large compensation amount reflects both the physical trauma sustained and the mental distress of the unprovoked assault.

Central to the lawsuit’s arguments is the allegation that correctional officials made a dangerously inadequate decision in placing Peterson with fellow inmate Santino Casio, who was completing a life sentence for murder in the second degree. The court documents asserts that the correctional department either knew or ought to have recognised that this housing arrangement posed a significant risk to Peterson, particularly given his prominent inmate status within the facility. Furthermore, the lawsuit challenges the actions of correctional staff, contending that guards did not use proper emergency procedures such as flash grenades to halt Casio’s attack. Notably, Casio was never charged with the assault despite inflicting 16 injuries on Peterson.

• Department of Corrections failed to prevent known dangerous inmate pairing
• Celebrity status rendered Peterson an identifiable target for attack
• Security personnel delayed response to stabbing emergency
• Prison failed to employ flash grenades or other containment measures
• Peterson’s personal possessions, such as unreleased songbooks, remain missing
