Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has launched a $100 million lawsuit against California’s Correctional Department after a severe stabbing incident whilst imprisoned at the California Correctional Institute in Tehachapi in May. The musician, known as Daystar Peterson and currently serving a 10-year prison term for the 2020 shooting of Megan Thee Stallion, was struck 16 times with a blade by prison inmate Santino Casio in what the lawsuit characterises as an “unprovoked life-threatening attack.” The assault left Peterson admitted to hospital with a collapsed lung and numerous stabbing injuries to his back, torso, and head. The lawsuit names the Department of Corrections, the prison warden, and guards as respondents, alleging carelessness regarding inmate placement and a delayed response to the violence.

The May 2025 Attack 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 completing a life sentence for second-degree murder, launched an unprovoked assault that left the rapper fighting for his life. Peterson sustained a punctured lung alongside multiple stab wounds across his back, torso, and head—injuries severe enough to warrant immediate hospitalisation. The attack raised serious questions about prison security protocols and inmate classification procedures, 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, representing another phase in his incarceration experience. The lawsuit additionally claims that during this move, Peterson did not regain his belongings from Tehachapi, including songbooks featuring lyrics to unreleased music—a loss that intensifies the physical and emotional trauma of the attack. Notably, despite the severity of the attack, Casio was not prosecuted in connection with the stabbing, a detail the lawsuit underscores as part of institutional breakdowns within the Department of Corrections.

• Casio stabbed Peterson 16 times during the unprovoked assault
• Peterson hospitalised with collapsed lung and several lacerations
• Transferred to California Men’s Colony following recovery
• Personal items, including songbooks, never recovered from Tehachapi

Claims of Negligence, and Organisational Breakdown

Accommodation Choices and Security Concerns

At the heart of Peterson’s lawsuit sits a fundamental criticism of the Corrections Department’s decision process regarding inmate housing assignments. The legal filing argues that housing Peterson alongside Santino Casio—a life-sentence prisoner serving time for murder in the second degree—represented a severe breakdown in risk assessment and prisoner classification. The lawsuit maintains that the department “knew or should have been known” to identify the inherent risk in this arrangement. Peterson’s prominent public profile, the suit maintains, made him an obvious target inside the correctional facility, rendering the accommodation choice not simply negligent but recklessly indifferent to his wellbeing and safety.

The lawsuit highlights that such accommodation determinations require careful consideration of detainee profiles, risk assessments, and possible drivers for violence. By not segregating Peterson from Casio, facility management purportedly showed a institutional indifference for core protective measures that should govern California’s detention centres. This failure of duty, the attorneys argues, immediately caused the environment where the stabbing occurred, converting what might have remained preventable violence into an completely anticipated consequence of systemic failure and insufficient safety provisions.

Response and Guard Conduct

Beyond the initial housing decision, the lawsuit challenges correctional officers’ response during the incident of violence. According to the complaint, correctional officers failed to act promptly when Casio launched his attack, allowing the violence to escalate unchecked. The lawsuit explicitly condemns the failure to deploy non-lethal devices or other non-lethal intervention methods that might have prevented further violence before Peterson incurred his most critical harm. This alleged slow reaction to an active stabbing incident suggests either inadequate training, understaffing, or a troubling disregard for prisoner safety—each possibility reflecting poorly on institutional competence.

The guards’ conduct during the critical minutes of the attack prompts inquiry into emergency protocols and staff preparedness within California’s prison system. Standard correctional procedures generally require rapid response to acts of violence, yet the lawsuit suggests this incident significantly departed from such protocols. The combined impact of delayed responses and the failure to implement proper tactical measures 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 situation requiring hospitalisation.

The Larger Context of Lanez’s Confinement

Tory Lanez’s current imprisonment originates from a widely publicized 2020 shooting incident involving rap artist Megan Thee Stallion. The altercation, which occurred during the 2020 summer months, led to Peterson firing at Stallion in her foot. Following a prolonged court proceedings, he was found guilty in December 2022 on several firearms charges, including assault with a firearm, and subsequently given a decade in prison. This conviction represented a significant moment in hip-hop, attracting extensive press coverage and igniting considerable debate within the music industry concerning responsibility and the events related to the incident.

Peterson’s court disputes have continued throughout his incarceration, with his attorneys lodging an appeal challenging the conviction and sentence. However, in November 2025, a three-judge panel denied his appeal and upheld the 10-year sentence originally imposed, essentially shutting down what many hoped would be an route to freedom or reduction in sentence. This denial came about six months after the stabbing attack at Tehachapi, meaning Peterson was grappling with both the psychological and physical aftermath of the prison attack whilst at the same time dealing with the disappointment of his failed appellate challenge. The confluence of these events has significantly complicated his situation in the California prison system.

Lawful Claims and Compensation Sought

Tory Lanez’s legal claim against the California Department of Corrections seeks $100 million in compensation, representing one of the most substantial suits filed against the state’s correctional system in recent times. The legal action 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 argues that institutional failures in prison management and security procedures led to the seriousness of Peterson’s injuries during the stabbing incident in May 2025. The significant financial award reflects both the physical injuries sustained and the mental distress of the unprovoked incident.

Central to the lawsuit’s arguments is the allegation that correctional officials made a dangerously inadequate choice in placing Peterson with cellmate Santino Casio, who was completing a life sentence for second-degree murder. The court documents asserts that the Department of Corrections either knew or should have known that this cell assignment posed a significant risk to Peterson, especially given his high-profile celebrity status within the prison. Furthermore, the lawsuit criticises the response of security personnel, arguing that guards did not use proper emergency procedures such as stun grenades to halt Casio’s attack. Notably, Casio was not prosecuted with the assault despite inflicting 16 injuries on Peterson.

• Correctional Department did not stop known dangerous inmate pairing
• Celebrity status made Peterson a recognisable target for attack
• Security personnel were slow to respond to stabbing incident
• Prison did not use flash grenades or alternative security measures
• Peterson’s belongings, such as unreleased songbooks, are unaccounted for
