Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has filed a $100 million lawsuit against California’s Department of Corrections following a brutal stabbing attack whilst incarcerated at the California Correctional Institute in Tehachapi last 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 prison inmate Santino Casio in what the lawsuit characterises as an “unprovoked dangerous assault.” The attack left Peterson admitted to hospital with a punctured lung and multiple stab wounds 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 delayed response 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 serving a life sentence for second-degree murder, launched an unprovoked assault that left the rapper struggling to survive. Peterson sustained a punctured lung alongside several stab injuries across his back, torso, and head—injuries severe enough to warrant immediate hospitalisation. The attack raised serious questions about prison security protocols and classification systems for inmates, particularly given the volatile circumstances of housing two inmates with such starkly different profiles and threat levels.

Following his return to health, Peterson was transferred to San Luis Obispo County’s California Men’s Colony, marking another chapter in his prison ordeal. 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 physical and emotional trauma of the incident. Notably, despite the severity of the attack, Casio was not charged in connection with the stabbing, a detail the lawsuit underscores as part of systemic failures within the correctional system.

• Casio attacked Peterson 16 times during the unprovoked assault
• Peterson admitted to hospital with collapsed lung and several lacerations
• Relocated to California Men’s Colony upon recovery
• Personal items, including songbooks, remained missing from Tehachapi

Allegations of Negligence, and Organisational Breakdown

Housing Decisions and Security Worries

At the core of Peterson’s lawsuit sits a fundamental criticism of the Corrections Department’s decision-making regarding prisoner accommodation placements. The court document contends that housing Peterson alongside Santino Casio—a lifer serving time for second-degree murder—constituted a catastrophic failure in risk assessment and prisoner classification. The lawsuit argues that the department “ought to have been aware” to recognise the danger inherent in this arrangement. Peterson’s prominent public status, the suit contends, rendered him an clear target within the prison environment, rendering the housing decision not simply negligent but callously indifferent to his wellbeing and safety.

The lawsuit emphasises that such accommodation determinations necessitate close examination of inmate backgrounds, risk assessments, and possible drivers for violence. By not segregating Peterson from Casio, correctional officials reportedly displayed a institutional indifference for core protective measures that must oversee California’s detention centres. This breach of care, the attorneys contends, directly precipitated the environment where the stabbing happened, changing what could have stayed preventable violence into an wholly predictable consequence of institutional mismanagement and insufficient safety provisions.

Response and Guard Behaviour

Beyond the initial housing decision, the lawsuit targets prison guards’ response during the actual assault. According to the complaint, correctional officers were slow to intervene when Casio carried out his attack, enabling the situation to worsen. The lawsuit directly challenges the failure to use flash grenades or other non-lethal tactical measures that might have prevented further violence before Peterson suffered his worst injuries. This alleged sluggishness in responding to an ongoing stabbing attack suggests either poor preparation, insufficient staffing, or a troubling disregard for prisoner safety—each possibility casting doubt on institutional competence.

The guards’ behaviour during the crucial minutes of the attack raises questions about emergency protocols and staff preparedness within California’s prison system. Typical prison protocols typically mandate rapid response to acts of violence, yet the lawsuit indicates this incident departed substantially from such protocols. The combined impact of slow response times and the lack of proper tactical measures meant that Peterson’s 16 stab wounds were inflicted with little active opposition from security personnel, converting what could have been a significant event into a life-threatening situation necessitating hospitalisation.

The Wider Context of Lanez’s Incarceration

Tory Lanez’s ongoing incarceration stems from a high-profile 2020 shooting incident involving fellow rapper Megan Thee Stallion. The confrontation, which took place in the 2020 summer months, led to Peterson shooting Stallion in the foot. After a prolonged court proceedings, he was convicted in December 2022 on multiple gun-related charges, including assault with a firearm, and subsequently sentenced to a decade in prison. This guilty verdict represented a major turning point in rap music, attracting extensive press coverage and sparking considerable debate within the music industry regarding responsibility and the events related to the incident.

Peterson’s court disputes have continued throughout his incarceration, with his legal team filing 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, effectively closing what many hoped would be an avenue for release or reduction in sentence. This rejection came about six months after the stabbing incident at Tehachapi, meaning Peterson was contending with both the psychological and physical aftermath of the prison attack whilst at the same time dealing with the frustration of his unsuccessful appellate challenge. The confluence of these events has significantly complicated his situation in the California correctional system.

Legal Claims and Compensation Sought

Tory Lanez’s legal claim against the California Department of Corrections pursues $100 million in financial restitution, amounting to one of the largest cases filed against the state’s correctional system in recent times. The lawsuit names the Department of Corrections as the primary defendant, alongside the warden and correctional officers stationed at the California Correctional Institute in Tehachapi. The lawsuit asserts that widespread deficiencies in facility operations and safety measures led to the severity of Peterson’s injuries during the May 2025 stabbing incident. The large compensation amount reflects both the physical injuries sustained and the mental distress of the unprovoked incident.

At the heart of the lawsuit’s claims is the allegation that prison authorities made a catastrophically poor decision in placing Peterson with fellow inmate Santino Casio, who was serving a life sentence for second-degree murder. The court documents 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 prominent inmate standing within the prison. Furthermore, the lawsuit challenges the response of correctional staff, contending that guards failed to employ proper emergency procedures such as flash grenades to halt Casio’s attack. Notably, Casio was not prosecuted with the assault despite inflicting 16 injuries on Peterson.

• Celebrity status rendered Peterson an identifiable target for attack
• Security personnel delayed response to stabbing incident
• Prison failed to employ flash grenades or other containment measures
