Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has filed a $100 million lawsuit against California’s Correctional Department following a brutal stabbing attack whilst incarcerated at the California Correctional Institute in Tehachapi in May. The musician, known as Daystar Peterson and presently completing a 10-year sentence 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 assault left Peterson hospitalised with a collapsed 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 slow reaction 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 second-degree murder, launched an unprovoked attack 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 prison security protocols and classification systems for inmates, particularly given the dangerous situation of housing two inmates with such starkly different profiles and threat levels.

Following his return to health, Peterson was moved to San Luis Obispo County’s California Men’s Colony, marking another chapter in his time in custody. The lawsuit further alleges that during this transfer, Peterson did not regain his personal items from Tehachapi, including songbooks containing lyrics to unpublished songs—a loss that intensifies the physical and emotional trauma of the attack. Notably, despite the seriousness of the assault, Casio was not charged in connection with the assault, a detail the lawsuit underscores as part of systemic shortcomings within the prison service.

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

Claims of Negligence and Organisational Breakdown

Housing Options and Security Concerns

At the heart of Peterson’s lawsuit sits a core criticism of the Corrections Department’s decision process regarding prisoner accommodation placements. The court document contends that placing Peterson with Santino Casio—a lifer serving time for second-degree murder—constituted a severe breakdown in risk assessment and prisoner classification. The lawsuit maintains that the department “ought to have been aware” to identify the inherent risk in this pairing. Peterson’s prominent public profile, the suit contends, made him an obvious target within the prison environment, making the accommodation choice not merely negligent but callously indifferent to his safety and wellbeing.

The lawsuit underscores that such housing decisions demand thorough evaluation of inmate backgrounds, security classifications, and potential motivations for violence. By neglecting to isolate Peterson from Casio, prison administrators allegedly demonstrated a widespread neglect for fundamental security procedures that should govern California’s detention centres. This negligence, the counsel contends, directly precipitated the environment where the stabbing took place, transforming what should have been preventable violence into an entirely foreseeable consequence of organisational negligence and substandard security arrangements.

Response and Security Conduct

Beyond the initial housing decision, the lawsuit takes aim at correctional officers’ response during the incident of violence. According to the filing, correctional officers were slow to intervene when Casio launched his attack, enabling the situation to worsen. The lawsuit explicitly condemns the failure to deploy non-lethal devices or other non-lethal tactical measures that might have halted the assault before Peterson suffered his worst injuries. This alleged sluggishness in responding to an active stabbing incident suggests either poor preparation, understaffing, or a troubling neglect of inmate wellbeing—each possibility casting doubt on institutional competence.

The guards’ conduct during the critical 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 acts of violence, yet the lawsuit suggests this incident departed substantially from such protocols. The cumulative effect of slow response times and the lack of proper tactical measures meant that Peterson’s 16 stab wounds were inflicted with minimal active resistance from security personnel, changing what could have been a significant event into a critical emergency necessitating hospitalisation.

The Larger Context of Lanez’s Incarceration

Tory Lanez’s current imprisonment originates from a high-profile 2020 shooting incident featuring rap artist Megan Thee Stallion. The altercation, which took place in the summer of 2020, 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 using a firearm, and subsequently given a decade in prison. This guilty verdict represented a significant moment in rap music, attracting widespread media attention and igniting substantial discussion across the music sector regarding accountability and the events related to the occurrence.

Peterson’s legal battles have continued throughout his incarceration, with his attorneys lodging an appeal contesting the conviction and sentence. However, in November 2025, a panel of three judges rejected his appeal and upheld the 10-year sentence originally imposed, effectively closing what many hoped would be an avenue for release or reduction in sentence. This denial came roughly six months after the stabbing attack at Tehachapi, meaning Peterson was contending with both the psychological and physical aftermath of the prison stabbing whilst whilst also processing the frustration of his failed appellate challenge. The confluence of these events has significantly complicated his experience within the California correctional system.

Lawful Claims and Compensation Requested

Tory Lanez’s legal claim against the California Department of Corrections demands $100 million in financial restitution, constituting one of the largest suits filed against the state’s correctional system in recent years. The legal action names the Department of Corrections as the principal defendant, alongside the warden and individual guards stationed at the California Correctional Institute in Tehachapi. The lawsuit argues that institutional failures in correctional management and security protocols directly contributed to the seriousness of Peterson’s injuries during the May 2025 stabbing incident. The significant financial award reflects both the physical trauma sustained and the emotional harm of the unprovoked assault.

At the heart of the lawsuit’s arguments is the allegation that prison authorities made a dangerously inadequate decision in housing Peterson with fellow inmate Santino Casio, who was serving a life term for second-degree murder. The legal filing asserts that the Department of Corrections either was aware or should have known that this housing arrangement posed a serious danger to Peterson, especially given his prominent inmate standing within the prison. Furthermore, the lawsuit criticises the actions of security personnel, arguing that guards failed to employ appropriate emergency measures such as stun grenades to halt Casio’s assault. Notably, Casio was not prosecuted with the assault despite causing 16 injuries on Peterson.

• Correctional Department did not stop 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, including unreleased songbooks, are unaccounted for
