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 imprisoned at the California Correctional Institute in Tehachapi last May. The artist, born Daystar Peterson and currently serving a 10-year sentence for the 2020 shooting of Megan Thee Stallion, was stabbed 16 times by prison inmate Santino Casio in what the lawsuit describes as an “unprovoked dangerous assault.” The attack left Peterson admitted to hospital with a punctured lung and numerous stabbing injuries 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 delayed response to the violence.

The May 2025 Incident 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 serving a life sentence for murder in the second degree, launched an unprovoked attack 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 emergency 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 recuperation, Peterson was moved to San Luis Obispo County’s California Men’s Colony, marking another chapter in his time in custody. The lawsuit further contends that during this relocation, Peterson did not regain his personal items from Tehachapi, including songbooks featuring lyrics to unreleased compositions—a loss that intensifies the psychological and physical harm of the incident. Notably, despite the seriousness of the assault, Casio was not charged in connection with the stabbing, a detail the lawsuit underscores as part of systemic failures within the prison service.

• Casio attacked Peterson 16 times during the unprovoked assault
• Peterson hospitalised with punctured lung and multiple wounds
• Moved to California Men’s Colony after recovery
• Personal belongings, including songbooks, never recovered from Tehachapi

Allegations of Negligence, and Systemic Failure

Housing Decisions and Safety Issues

At the heart of Peterson’s lawsuit sits a fundamental criticism of the Corrections Department’s decision process concerning inmate housing assignments. The legal filing argues that housing Peterson alongside Santino Casio—a lifer incarcerated for murder in the second degree—constituted a severe breakdown in risk assessment and prisoner classification. The lawsuit maintains that the department “ought to have been aware” to identify the danger inherent in this arrangement. Peterson’s prominent public status, the suit contends, rendered him an obvious target within the prison environment, rendering the housing decision not merely negligent but recklessly indifferent to his safety and wellbeing.

The lawsuit underscores that such housing decisions require careful consideration of inmate backgrounds, threat levels, and underlying reasons for violence. By failing to separate Peterson from Casio, facility management reportedly displayed a widespread neglect for basic safety protocols that must oversee California’s correctional facilities. This breach of care, the attorneys maintains, substantially contributed to the environment where the stabbing occurred, transforming what should have been preventable violence into an wholly predictable consequence of institutional mismanagement and substandard security arrangements.

Response and Guard Conduct

Beyond the initial housing decision, the lawsuit takes aim at correctional officers’ response during the actual assault. According to the complaint, correctional officers delayed their intervention when Casio initiated the assault, enabling the situation to worsen. The lawsuit directly challenges the failure to employ flash grenades or other non-lethal intervention methods that might have prevented further violence before Peterson suffered his worst injuries. This alleged slow reaction to an active stabbing incident suggests either insufficient training, insufficient staffing, or a troubling neglect of inmate wellbeing—each possibility casting doubt on institutional competence.

The guards’ behaviour during the critical minutes of the attack calls into question emergency protocols and staff preparedness within California’s prison system. Standard correctional procedures typically mandate immediate intervention to violent incidents, yet the lawsuit contends this incident deviated significantly from such protocols. The aggregate consequence of sluggish reaction times and the lack of proper tactical measures 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 situation necessitating hospitalisation.

The Wider Context of Lanez’s Imprisonment

Tory Lanez’s current imprisonment originates from a widely publicized 2020 shooting incident featuring rap artist Megan Thee Stallion. The confrontation, which occurred during the 2020 summer months, resulted in Peterson shooting Stallion in the foot. After a lengthy legal process, he was convicted in December 2022 on multiple gun-related charges, including assault with a firearm, and thereafter given a decade in prison. This guilty verdict represented a significant moment in hip-hop, attracting extensive press coverage and igniting substantial discussion within the music industry concerning responsibility and the events related to the occurrence.

Peterson’s legal battles have continued throughout his incarceration, with his attorneys mounting an appeal contesting the conviction and sentence. However, in November 2025, a three-judge panel rejected his appeal and maintained the original 10-year sentence, essentially shutting down what many anticipated as an route to freedom or reduction in sentence. This rejection came roughly 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 disappointment of his unsuccessful appellate challenge. The confluence of these events has markedly worsened his situation in the California prison system.

Legal Claims and Compensation Requested

Tory Lanez’s court action against the California Department of Corrections demands $100 million in damages, amounting to one of the most substantial claims filed against the state’s correctional system in recent times. The legal action names the Department of Corrections as the principal defendant, in addition to the warden and correctional officers stationed at the California Correctional Institute in Tehachapi. The lawsuit asserts that widespread deficiencies in prison management and safety measures directly contributed to the extent of Peterson’s injuries during the 2025 stabbing attack. The significant financial award reflects both the physical trauma sustained and the emotional harm of the unprovoked incident.

Central to the lawsuit’s claims is the allegation that correctional officials made a catastrophically poor decision in placing Peterson with fellow inmate Santino Casio, who was serving a life sentence for murder in the second degree. The legal filing 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 prominent inmate status within the facility. Furthermore, the lawsuit criticises the response of correctional staff, 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 assault despite inflicting 16 injuries on Peterson.
