Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has launched a $100 million legal action against California’s Correctional Department following a severe stabbing incident whilst imprisoned at the California Correctional Institute in Tehachapi in May. The musician, born Daystar Peterson and currently serving a 10-year prison term for the 2020 shooting incident involving Megan Thee Stallion, was stabbed 16 times by fellow inmate Santino Casio in what the lawsuit describes as an “unprovoked life-threatening attack.” The assault 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 prison warden, and guards as respondents, alleging negligence in housing decisions and a slow reaction to the violence.

The May 2025 Incident and Its Consequences

The May 2025 stabbing incident at Tehachapi marked 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 multiple stab wounds across his back, torso, and head—injuries severe enough to warrant emergency hospitalisation. The attack raised serious questions about security procedures in prisons and inmate classification procedures, particularly given the dangerous situation of housing two inmates with such markedly different profiles and threat levels.

Following his recuperation, Peterson was transferred to San Luis Obispo County’s California Men’s Colony, constituting another stage in his time in custody. The lawsuit further alleges that during this transfer, Peterson never recovered his personal possessions from Tehachapi, including songbooks containing lyrics to unpublished songs—a loss that intensifies the psychological and physical harm of the assault. Notably, despite the severity of the attack, Casio was not charged in connection with the assault, a detail the lawsuit highlights as part of institutional breakdowns within the correctional system.

• Casio stabbed Peterson 16 times during the unprovoked assault
• Peterson admitted to hospital with punctured lung and multiple wounds
• Relocated to California Men’s Colony upon recovery
• Personal possessions, including songbooks, not recovered from Tehachapi

Claims of Negligence, and Institutional Failure

Housing Options and Security Concerns

At the heart of Peterson’s lawsuit lies a fundamental criticism of the Department of Corrections’ decision process concerning prisoner accommodation placements. The court document contends that placing Peterson alongside Santino Casio—a lifer incarcerated for second-degree murder—represented a catastrophic failure in risk evaluation and inmate classification. The lawsuit argues that the department “knew or should have been known” to recognise the inherent risk in this arrangement. Peterson’s prominent public profile, the suit maintains, rendered him an obvious target inside the correctional facility, making the housing decision not merely negligent but recklessly indifferent to his wellbeing and safety.

The lawsuit highlights that such placement choices demand thorough evaluation of prisoner histories, threat levels, and underlying reasons for violence. By not segregating Peterson from Casio, prison administrators reportedly displayed a institutional indifference for basic safety protocols that should govern California’s prison system. This negligence, the legal team argues, substantially contributed to the conditions under which the stabbing occurred, changing what could have stayed preventable violence into an entirely foreseeable consequence of institutional mismanagement and substandard security arrangements.

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 launched his attack, permitting violence to continue unabated. The lawsuit specifically criticises the failure to use flash grenades or other non-lethal intervention methods that might have stopped the attack before Peterson incurred his most critical harm. This alleged slow reaction to an active stabbing incident suggests either insufficient training, insufficient staffing, or a troubling indifference to inmate welfare—each possibility casting doubt on institutional competence.

The guards’ conduct during the critical minutes of the attack calls into question emergency procedures and personnel readiness within California’s prison system. Typical prison protocols generally require rapid response to acts of violence, yet the lawsuit indicates this incident significantly departed from such protocols. The aggregate consequence of sluggish reaction times and the lack of appropriate tactical intervention meant that Peterson’s 16 stab wounds were inflicted with scant active defence from security personnel, converting what could have been a grave occurrence into a life-threatening emergency demanding hospital treatment.

The Wider Context of Lanez’s Confinement

Tory Lanez’s ongoing incarceration originates from a widely publicized 2020 shooting incident involving fellow rapper Megan Thee Stallion. The confrontation, which occurred during the 2020 summer months, resulted in Peterson shooting Stallion in the foot. After a prolonged court proceedings, he was convicted in December 2022 on several firearms charges, including assault with a firearm, and subsequently sentenced to a decade in prison. This conviction marked a significant moment in rap music, drawing extensive press coverage and sparking considerable debate across the music sector regarding responsibility and the events related to the incident.

Peterson’s ongoing litigation have continued throughout his incarceration, with his defence counsel lodging an appeal challenging the conviction and sentence. However, in November 2025, a panel of three judges rejected his appeal and confirmed the 10-year sentence originally imposed, essentially shutting down what many anticipated as an route to freedom or sentence reduction. This denial came approximately six months after the stabbing attack at Tehachapi, meaning Peterson was contending with both the physical and psychological aftermath of the prison attack whilst whilst also processing the frustration of his unsuccessful appellate challenge. The convergence of these circumstances has significantly complicated his circumstances within the California prison system.

Lawful Claims and Compensation Requested

Tory Lanez’s legal claim against the California Department of Corrections pursues $100 million in damages, amounting to one of the most substantial claims filed against the state’s correctional system in the past several years. The legal action names the Department of Corrections as the main defendant, together with the warden and individual guards stationed at the California Correctional Institute in Tehachapi. The lawsuit argues that institutional failures in correctional management and security procedures directly contributed to the seriousness of Peterson’s injuries during the May 2025 stabbing incident. The substantial compensation figure reflects both the bodily harm sustained and the psychological impact of the unprovoked attack.

At the heart of the lawsuit’s claims is the assertion that prison authorities made a dangerously inadequate choice in placing Peterson with fellow inmate Santino Casio, who was completing a life term for second-degree murder. The legal filing asserts that the correctional department either was aware or should have known that this housing arrangement posed a significant risk to Peterson, particularly given his high-profile celebrity standing within the facility. Furthermore, the lawsuit criticises the actions of security personnel, contending that officers 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 failed to prevent identified high-risk inmate pairing
• Celebrity status rendered Peterson a recognisable 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, remain missing
