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 severe stabbing incident whilst imprisoned at the California Correctional Institute in Tehachapi last May. The artist, born Daystar Peterson and presently completing a 10-year prison term for the 2020 shooting incident involving 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 numerous stabbing injuries to his back, torso, and head. The lawsuit identifies the Department of Corrections, the prison warden, and guards as defendants, 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 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 attack 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 significant concerns about prison security protocols and inmate classification procedures, particularly given the dangerous situation of housing two inmates with such starkly different profiles and threat levels.

Following his recovery, Peterson was transferred to San Luis Obispo County’s California Men’s Colony, representing another phase in his incarceration experience. The lawsuit further contends that during this relocation, Peterson did not regain his personal possessions from Tehachapi, including songbooks containing lyrics to unreleased compositions—a loss that exacerbates the physical and emotional trauma of the incident. Notably, despite the gravity of the incident, Casio was not prosecuted in connection with the assault, a detail the lawsuit emphasises as part of systemic failures within the correctional system.

• Casio struck Peterson 16 times during the unprovoked incident
• Peterson admitted to hospital with collapsed lung and several lacerations
• Moved to California Men’s Colony after recovery
• Personal possessions, including songbooks, remained missing from Tehachapi

Accusations of Negligence and Organisational Breakdown

Housing Decisions and Safety Issues

At the core of Peterson’s lawsuit lies a fundamental challenge of the Corrections Department’s decision-making regarding prisoner accommodation placements. The court document contends that housing Peterson alongside Santino Casio—a life-sentence prisoner incarcerated for second-degree murder—constituted a catastrophic failure in risk assessment and prisoner classification. The lawsuit maintains that the department “ought to have been aware” to recognise the danger inherent in this pairing. Peterson’s prominent public profile, the suit contends, made him an obvious target inside the correctional environment, rendering the housing decision not merely negligent but callously indifferent to his safety and wellbeing.

The lawsuit underscores that such placement choices necessitate close examination of inmate backgrounds, security classifications, and underlying reasons for violence. By failing to separate Peterson from Casio, prison administrators reportedly displayed a institutional indifference for basic safety protocols that must oversee California’s detention centres. This negligence, the attorneys maintains, substantially contributed to the conditions under which the stabbing happened, converting what might have remained preventable violence into an entirely foreseeable consequence of institutional mismanagement and substandard security arrangements.

Response and Guard Conduct

Beyond the initial housing decision, the lawsuit challenges prison guards’ response during the incident of violence. According to the filing, correctional officers were slow to intervene when Casio carried out his attack, enabling the situation to worsen. The lawsuit directly challenges the failure to employ flash grenades or other non-lethal tactical measures that might have prevented further violence before Peterson incurred his most critical harm. This alleged sluggishness in responding to an active stabbing incident suggests either inadequate training, understaffing, or a troubling indifference to inmate welfare—each possibility undermining institutional competence.

The guards’ behaviour during the crucial minutes of the attack calls into question emergency protocols and personnel readiness within California’s prison system. Standard correctional procedures ordinarily stipulate rapid response to violent incidents, yet the lawsuit contends this incident departed substantially from such protocols. The aggregate consequence of delayed responses and the lack of appropriate tactical intervention meant that Peterson’s 16 stab wounds were inflicted with scant active defence from security personnel, transforming what could have been a significant event into a critical emergency necessitating hospitalisation.

The Larger Context of Lanez’s Confinement

Tory Lanez’s current imprisonment stems from a high-profile shooting event in 2020 featuring fellow rapper Megan Thee Stallion. The confrontation, which took place in the 2020 summer months, resulted in Peterson firing at Stallion in her foot. Following a prolonged court proceedings, he was convicted in December 2022 on several firearms charges, such as assault with a firearm, and subsequently sentenced to a decade in prison. This guilty verdict represented a significant moment in rap music, drawing extensive press coverage and sparking considerable debate within the music industry regarding responsibility and the circumstances surrounding the occurrence.

Peterson’s legal battles have persisted during his incarceration, with his defence counsel filing an appeal contesting the conviction and sentence. However, in November 2025, a panel of three judges rejected his appeal and confirmed the original 10-year sentence, effectively closing what many hoped would be an route to freedom or reduction in sentence. This denial came approximately six months after the stabbing incident at Tehachapi, meaning Peterson was contending with both the physical and psychological aftermath of the prison stabbing whilst at the same time dealing with the frustration of his unsuccessful appellate challenge. The combination of these events 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 seeks $100 million in compensation, representing one of the most significant suits filed against the state’s correctional system in recent times. The legal action names the Department of Corrections as the primary defendant, in addition to the warden and individual guards stationed at the California Correctional Institute in Tehachapi. The lawsuit contends that systemic failures in prison management and security procedures directly contributed to the severity of Peterson’s injuries during the stabbing incident in May 2025. The large compensation amount reflects both the physical trauma sustained and the mental distress of the unprovoked incident.

Central to the lawsuit’s arguments is the allegation that prison authorities made a catastrophically poor choice in placing Peterson with cellmate Santino Casio, who was completing a life sentence for murder in the second degree. The legal filing asserts that the correctional department either knew or ought to have recognised that this cell assignment posed a serious danger to Peterson, especially given his prominent inmate status within the prison. Furthermore, the lawsuit criticises the actions of correctional staff, contending that guards did not use appropriate emergency measures such as flash grenades to stop Casio’s assault. Notably, Casio was not prosecuted with the assault despite inflicting 16 injuries on Peterson.
