Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has filed a $100 million legal action against California’s Correctional Department 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 stabbed 16 times by fellow inmate Santino Casio in what the lawsuit characterises as an “unprovoked life-threatening attack.” The assault left Peterson hospitalised with a collapsed lung and numerous stabbing injuries to his back, torso, and head. The lawsuit names the Department of Corrections, the facility warden, and guards as respondents, alleging negligence in housing decisions and a slow reaction to the violence.

The May 2025 Attack and Its Aftermath

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 assault that left the rapper struggling to survive. Peterson sustained a collapsed lung alongside several stab injuries across his back, torso, and head—injuries severe enough to warrant immediate hospitalisation. The attack raised significant concerns about security procedures in prisons and classification systems for inmates, particularly given the dangerous situation of housing two inmates with such markedly different profiles and threat levels.

Following his recovery, Peterson was moved to San Luis Obispo County’s California Men’s Colony, constituting another stage in his incarceration experience. The lawsuit further alleges that during this relocation, Peterson failed to retrieve his personal possessions from Tehachapi, including songbooks with lyrics to unreleased music—a loss that compounds the psychological and physical harm of the attack. Notably, despite the severity of the attack, Casio was not held accountable in connection with the stabbing, a detail the lawsuit underscores as part of systemic shortcomings within the Department of Corrections.

• Casio struck Peterson 16 times during the unprovoked assault
• Peterson admitted to hospital with collapsed lung and numerous injuries
• Moved to California Men’s Colony after recovery
• Personal items, including songbooks, never recovered from Tehachapi

Allegations of Negligence and Systemic Failure

Housing Options and Security Concerns

At the core of Peterson’s lawsuit sits a fundamental challenge of the Department of Corrections’ decision-making regarding prisoner accommodation placements. The court document argues that placing Peterson with Santino Casio—a lifer serving time for murder in the second degree—constituted a catastrophic failure in risk assessment and prisoner classification. The lawsuit argues that the department “knew or should have been known” to identify the danger inherent in this pairing. Peterson’s prominent public status, the suit contends, made him an obvious target within the prison facility, making the housing decision not simply negligent but callously indifferent to his wellbeing and safety.

The lawsuit emphasises that such housing decisions demand thorough evaluation of detainee profiles, security classifications, and potential motivations for violence. By not segregating Peterson from Casio, correctional officials purportedly showed a institutional indifference for fundamental security procedures that should govern California’s detention centres. This negligence, the legal team contends, directly precipitated the environment where the stabbing took place, converting what might have remained preventable violence into an entirely foreseeable consequence of institutional mismanagement and substandard security arrangements.

Response and Security Behaviour

Beyond the initial housing decision, the lawsuit challenges prison guards’ response during the incident of violence. According to the filing, correctional officers delayed their intervention when Casio carried out his attack, permitting violence to continue unabated. The lawsuit directly challenges the failure to use flash grenades or other non-lethal intervention methods that might have stopped the attack before Peterson suffered his worst injuries. This alleged slow reaction to an ongoing stabbing attack suggests either poor preparation, understaffing, or a troubling indifference to inmate welfare—each possibility reflecting poorly on institutional competence.

The guards’ actions during the crucial minutes of the attack raises questions about emergency procedures and staff preparedness within California’s prison system. Standard correctional procedures ordinarily stipulate rapid response to violent incidents, yet the lawsuit indicates this incident deviated significantly from such protocols. The cumulative effect of slow response times and the absence of proper tactical measures 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 critical emergency demanding hospital treatment.

The Wider Context of Lanez’s Confinement

Tory Lanez’s ongoing incarceration originates from a high-profile 2020 shooting incident featuring rap artist Megan Thee Stallion. The confrontation, which occurred during the summer of 2020, led to Peterson firing at Stallion in her foot. Following a prolonged court proceedings, he was convicted in December 2022 on several firearms charges, including assault with a firearm, and thereafter given a decade in prison. This guilty verdict represented a significant moment in rap music, attracting widespread media attention and igniting considerable debate within the music industry regarding responsibility and the circumstances surrounding the incident.

Peterson’s legal battles have persisted during his incarceration, with his legal team mounting an appeal contesting the conviction and sentence. However, in November 2025, a three-judge panel denied his appeal and confirmed the original 10-year sentence, essentially shutting down what many anticipated as an path to release or reduction in sentence. This rejection came about six months after the stabbing attack at Tehachapi, meaning Peterson was grappling with both the physical and psychological aftermath of the prison stabbing whilst whilst also processing the frustration of his unsuccessful appeal. The convergence of these circumstances has significantly complicated his circumstances within the California correctional system.

Legal Claims and Compensation Sought

Tory Lanez’s lawsuit against the California Department of Corrections pursues $100 million in damages, representing one of the most substantial suits filed against the state’s correctional system in recent times. The court filing names the Department of Corrections as the primary defendant, alongside the warden and individual guards stationed at the California Correctional Institute in Tehachapi. The lawsuit asserts that institutional failures in prison management and security procedures resulted in the severity of Peterson’s injuries during the 2025 stabbing attack. The significant financial award reflects both the physical injuries sustained and the mental distress of the unprovoked attack.

Central to the lawsuit’s claims is the allegation that correctional officials made a dangerously inadequate decision in placing Peterson with cellmate Santino Casio, who was serving a life sentence for murder in the second degree. The court documents contends that the correctional department either was aware or should have known that this cell assignment posed a serious danger to Peterson, particularly given his high-profile celebrity status within the facility. Furthermore, the lawsuit challenges the actions of correctional staff, arguing that officers did not use appropriate emergency measures such as flash grenades to stop Casio’s assault. Notably, Casio was not prosecuted with the assault despite inflicting sixteen wounds on Peterson.

• Department of Corrections did not stop known dangerous inmate pairing
• Celebrity status made Peterson a recognisable target for violence
• Security personnel were slow to respond to stabbing incident
• Prison failed to employ flash grenades or other containment measures
• Peterson’s belongings, including unreleased songbooks, are unaccounted for
