Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has filed a $100 million legal action against California’s Correctional Department after a severe stabbing incident whilst imprisoned at the California Correctional Institute in Tehachapi in May. The artist, 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 prison inmate Santino Casio in what the lawsuit describes as an “unprovoked dangerous assault.” The assault left Peterson admitted to hospital with a punctured lung and numerous stabbing injuries to his back, torso, and head. The lawsuit names the Department of Corrections, the prison warden, and guards as defendants, alleging negligence in housing decisions and a slow reaction to the violence.

The May 2025 Attack 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 completing a life sentence for second-degree murder, launched an unprovoked assault that left the rapper fighting for his life. 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 inmate classification procedures, particularly given the dangerous situation of housing two inmates with such markedly different profiles and threat levels.

Following his return to health, Peterson was moved to San Luis Obispo County’s California Men’s Colony, representing another phase in his incarceration experience. The lawsuit additionally claims that during this relocation, Peterson failed to retrieve his belongings from Tehachapi, including songbooks with lyrics to unreleased compositions—a loss that compounds the emotional and physical suffering of the assault. Notably, despite the seriousness of the assault, Casio was not charged in connection with the assault, a detail the lawsuit highlights as part of systemic failures within the correctional system.

• Casio attacked Peterson 16 times during the unprovoked incident
• Peterson admitted to hospital with punctured lung and multiple wounds
• Relocated to California Men’s Colony upon recovery
• Personal belongings, including songbooks, remained missing from Tehachapi

Allegations of Negligence and Organisational Breakdown

Housing Options and Safety Issues

At the core of Peterson’s lawsuit lies a fundamental challenge of the Department of Corrections’ decision-making regarding inmate housing assignments. The legal filing argues that housing Peterson with Santino Casio—a life-sentence prisoner incarcerated for second-degree murder—represented a catastrophic failure in risk evaluation and inmate classification. The lawsuit maintains that the department “ought to have been aware” to identify the danger inherent in this pairing. Peterson’s high-profile celebrity status, the suit contends, made him an clear target within the prison environment, making the accommodation choice not merely negligent but recklessly indifferent to his safety and wellbeing.

The lawsuit emphasises that such placement choices demand thorough evaluation of detainee profiles, threat levels, and possible drivers for violence. By neglecting to isolate Peterson from Casio, facility management purportedly showed a systemic disregard for basic safety protocols that should govern California’s detention centres. This breach of care, the counsel maintains, directly precipitated the environment where the stabbing occurred, changing what could have stayed preventable violence into an entirely foreseeable consequence of organisational negligence and insufficient safety provisions.

Response and Security Behaviour

Beyond the initial housing decision, the lawsuit targets correctional officers’ response during the incident of violence. According to the filing, correctional officers delayed their intervention when Casio launched his attack, enabling the situation to worsen. The lawsuit directly challenges the failure to deploy non-lethal devices or other non-lethal tactical measures that might have stopped the attack before Peterson suffered his worst injuries. This alleged delay in response to an active stabbing incident suggests either inadequate training, understaffing, or a troubling neglect of inmate wellbeing—each possibility casting doubt on institutional competence.

The guards’ behaviour during the crucial minutes of the attack calls into question emergency procedures and staff preparedness within California’s prison system. Typical prison protocols ordinarily stipulate rapid response to acts of violence, yet the lawsuit suggests this incident significantly departed from such protocols. The aggregate consequence of slow response times and the failure to implement 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 serious incident into a critical emergency requiring hospitalisation.

The Expanded Context of Lanez’s Imprisonment

Tory Lanez’s ongoing incarceration originates from a high-profile 2020 shooting incident featuring fellow rapper Megan Thee Stallion. The altercation, which took place in the summer of 2020, led to Peterson firing at Stallion in the foot. Following a lengthy legal process, he was found guilty in December 2022 on multiple gun-related charges, including assault with a firearm, and subsequently sentenced to a ten-year prison sentence. This guilty verdict represented a significant moment in hip-hop, attracting extensive press coverage and sparking substantial discussion across the music sector concerning accountability and the circumstances surrounding the incident.

Peterson’s court disputes have persisted during his incarceration, with his attorneys lodging an appeal challenging the conviction and sentence. However, in November 2025, a panel of three judges denied his appeal and confirmed the original 10-year sentence, essentially shutting down what many anticipated as an route to freedom or reduction in sentence. This denial came roughly six months after the stabbing incident at Tehachapi, meaning Peterson was grappling with both the psychological and physical aftermath of the prison attack whilst simultaneously processing the frustration of his unsuccessful appeal. The convergence of these circumstances has markedly worsened his circumstances within the California correctional system.

Legal Claims and Compensation Sought

Tory Lanez’s court action against the California Department of Corrections seeks $100 million in financial restitution, amounting to one of the most significant claims filed against the state’s correctional system in the past several years. The court filing names the Department of Corrections as the principal defendant, together with the warden and prison staff stationed at the California Correctional Institute in Tehachapi. The lawsuit asserts that widespread deficiencies in facility operations and security protocols led to the extent of Peterson’s injuries during the 2025 stabbing attack. The significant financial award reflects both the bodily harm sustained and the psychological impact of the unprovoked incident.

At the heart of the lawsuit’s arguments is the assertion that correctional officials made a catastrophically poor choice in placing Peterson with cellmate Santino Casio, who was completing a life sentence for second-degree murder. The legal filing contends that the Department of Corrections either knew or should have known that this cell assignment posed a significant risk to Peterson, particularly given his prominent inmate status within the facility. Furthermore, the lawsuit challenges the actions of security personnel, arguing that guards did not use proper emergency procedures such as flash grenades to halt Casio’s attack. Notably, Casio was never charged with the stabbing despite inflicting sixteen wounds on Peterson.

• Correctional Department failed to prevent known dangerous inmate pairing
• Celebrity status made Peterson a recognisable target for violence
• Security personnel delayed response to stabbing emergency
• Prison failed to employ flash grenades or alternative security measures
• Peterson’s personal possessions, such as unreleased songbooks, remain missing
