Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has launched a $100 million lawsuit against California’s Department of Corrections after a severe stabbing incident whilst incarcerated at the California Correctional Institute in Tehachapi last May. The musician, known as Daystar Peterson and presently completing a 10-year prison term for the 2020 shooting of Megan Thee Stallion, was struck 16 times with a blade by fellow inmate Santino Casio in what the lawsuit describes as an “unprovoked life-threatening attack.” The attack left Peterson hospitalised with a punctured lung and multiple stab wounds to his back, torso, and head. The lawsuit identifies the Department of Corrections, the facility warden, and guards as respondents, alleging carelessness regarding inmate placement and a slow reaction to the violence.

The May 2025 Incident and Its Aftermath

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 completing a life sentence for second-degree murder, launched an unprovoked assault that left the rapper fighting for his life. Peterson sustained a collapsed lung alongside multiple stab wounds across his back, torso, and head—injuries serious enough to warrant emergency hospitalisation. The attack raised significant concerns about prison security protocols and classification systems for inmates, particularly given the dangerous situation 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 incarceration experience. The lawsuit further contends that during this transfer, Peterson did not regain his belongings from Tehachapi, including songbooks with lyrics to unpublished songs—a loss that exacerbates the emotional and physical suffering of the incident. Notably, despite the seriousness of the assault, 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 stabbed Peterson 16 times during the unprovoked attack
• Peterson admitted to hospital with collapsed lung and several lacerations
• Moved to California Men’s Colony upon recovery
• Personal belongings, including songbooks, not recovered from Tehachapi

Accusations of Negligence, and Organisational Breakdown

Housing Options and Security Concerns

At the heart of Peterson’s lawsuit lies a core challenge of the Corrections Department’s decision-making concerning inmate housing assignments. The court document argues that housing Peterson alongside Santino Casio—a life-sentence prisoner serving time for murder in the second degree—represented a severe breakdown in risk assessment and inmate classification. The lawsuit maintains that the department “ought to have been aware” to recognise the danger inherent in this arrangement. Peterson’s high-profile celebrity status, the suit maintains, rendered him an clear target inside the correctional environment, rendering the accommodation choice not merely negligent but callously indifferent to his wellbeing and safety.

The lawsuit highlights that such placement choices demand thorough evaluation of detainee profiles, security classifications, and possible drivers for violence. By neglecting to isolate Peterson from Casio, facility management reportedly displayed a institutional indifference for fundamental security procedures that should govern California’s correctional facilities. This failure of duty, the counsel argues, directly precipitated the conditions under which the stabbing occurred, converting what might have remained preventable violence into an wholly predictable consequence of organisational negligence and substandard security arrangements.

Response and Guard Behaviour

Beyond the primary accommodation decision, the lawsuit targets correctional officers’ response during the incident of violence. According to the filing, correctional officers delayed their intervention when Casio launched his attack, enabling the situation to worsen. The lawsuit explicitly condemns the failure to use flash grenades or other non-lethal intervention methods that might have halted the assault before Peterson incurred his most critical harm. This alleged slow reaction to an ongoing stabbing attack suggests either inadequate training, inadequate staffing, or a troubling neglect of inmate wellbeing—each possibility reflecting poorly on institutional competence.

The guards’ behaviour during the critical minutes of the attack raises questions about emergency protocols and staff preparedness within California’s prison system. Conventional correctional practices generally require rapid response to acts of violence, yet the lawsuit suggests this incident significantly departed from such protocols. The combined impact of slow response times and the lack of suitable tactical response meant that Peterson’s 16 stab wounds were inflicted with minimal active resistance from security personnel, transforming what could have been a grave occurrence into a critical emergency necessitating hospitalisation.

The Larger Context of Lanez’s Confinement

Tory Lanez’s ongoing incarceration originates from a widely publicized 2020 shooting incident featuring fellow rapper Megan Thee Stallion. The confrontation, which took place in the summer of 2020, resulted in Peterson firing at Stallion in her foot. After a lengthy legal process, he was convicted in December 2022 on several firearms charges, such as assault with a firearm, and thereafter given a decade in prison. This guilty verdict represented a significant moment in rap music, drawing widespread media attention and sparking considerable debate within the music industry regarding accountability 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 three-judge panel denied his appeal and confirmed the 10-year sentence originally imposed, essentially shutting down what many hoped would be an path to release or reduction in sentence. This rejection came roughly 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 appellate challenge. The convergence of these circumstances has markedly worsened his experience within the California correctional system.

Legal Claims and Damages Claimed

Tory Lanez’s legal claim against the California Department of Corrections pursues $100 million in damages, representing one of the most substantial claims filed against the state’s correctional system in recent times. The court filing 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 contends that institutional failures in prison management and security protocols resulted in the seriousness of Peterson’s injuries during the 2025 stabbing attack. The substantial compensation figure reflects both the physical trauma sustained and the mental distress of the unprovoked attack.

Central to the lawsuit’s arguments is the assertion that prison authorities made a catastrophically poor decision in housing Peterson with fellow inmate Santino Casio, who was completing a life term for second-degree murder. The legal filing contends that the correctional department either was aware or ought to have recognised that this housing arrangement posed a serious danger to Peterson, particularly given his high-profile celebrity status within the prison. Furthermore, the lawsuit challenges the actions of security personnel, arguing that officers failed to employ proper emergency procedures such as flash grenades to halt Casio’s assault. Notably, Casio was not prosecuted with the stabbing despite inflicting 16 injuries on Peterson.

• Correctional Department did not stop identified high-risk inmate pairing
• Celebrity status rendered Peterson an identifiable target for attack
• Security personnel were slow to respond to stabbing emergency
• Prison did not use flash grenades or alternative security measures
• Peterson’s personal possessions, such as unreleased songbooks, are unaccounted for
