Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has filed a $100 million legal action against California’s Department of Corrections following a brutal stabbing attack whilst incarcerated at the California Correctional Institute in Tehachapi last May. The musician, born 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 describes as an “unprovoked life-threatening attack.” The attack left Peterson admitted to hospital 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 carelessness regarding inmate placement and a slow reaction to the violence.

The May 2025 Attack and Its Consequences

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 serving a life sentence for second-degree murder, launched an unprovoked attack that left the rapper struggling to survive. Peterson sustained a collapsed lung alongside multiple stab wounds across his back, torso, and head—injuries serious enough to warrant immediate 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 return to health, Peterson was moved to San Luis Obispo County’s California Men’s Colony, marking another chapter in his incarceration experience. The lawsuit further alleges that during this move, Peterson failed to retrieve his personal possessions from Tehachapi, including songbooks with lyrics to unreleased music—a loss that exacerbates the psychological and physical harm of the attack. Notably, despite the seriousness of the assault, Casio was not charged in connection with the knife attack, a detail the lawsuit emphasises as part of institutional breakdowns within the prison service.

• Casio stabbed Peterson 16 times during the unprovoked incident
• Peterson admitted to hospital with punctured lung and numerous injuries
• Relocated to California Men’s Colony after recovery
• Personal belongings, including songbooks, never recovered from Tehachapi

Accusations of Negligence, and Institutional Failure

Accommodation Choices and Security Concerns

At the heart of Peterson’s lawsuit sits a fundamental challenge of the Corrections Department’s decision-making concerning inmate housing assignments. The court document contends that housing Peterson alongside Santino Casio—a life-sentence prisoner incarcerated for murder in the second degree—represented a severe breakdown in risk assessment and prisoner classification. The lawsuit argues that the department “knew or should have been known” to identify the inherent risk in this pairing. Peterson’s high-profile celebrity profile, the suit contends, rendered him an clear target inside the correctional facility, rendering the accommodation choice not merely negligent but callously indifferent to his wellbeing and safety.

The lawsuit emphasises that such accommodation determinations require careful consideration of prisoner histories, threat levels, and underlying reasons for violence. By not segregating Peterson from Casio, facility management allegedly demonstrated a systemic disregard for fundamental security procedures that should govern California’s prison system. This failure of duty, the attorneys maintains, immediately caused the conditions under which the stabbing happened, transforming what should have been preventable violence into an wholly predictable consequence of organisational negligence and insufficient safety provisions.

Response and Guard Conduct

Beyond the initial housing decision, the lawsuit targets correctional officers’ response during the incident of violence. According to the complaint, correctional officers delayed their intervention when Casio launched his attack, allowing the violence to escalate unchecked. The lawsuit directly challenges the failure to use flash grenades or other non-lethal tactical measures that might have halted the assault before Peterson incurred his most critical harm. This alleged delay in response to an ongoing stabbing attack suggests either poor preparation, understaffing, or a troubling disregard for prisoner safety—each possibility undermining institutional competence.

The guards’ behaviour during the crucial minutes of the attack calls into question emergency procedures and personnel readiness within California’s prison system. Typical prison protocols typically mandate immediate intervention to acts of violence, yet the lawsuit contends this incident departed substantially from such protocols. The aggregate consequence of sluggish reaction times and the absence of suitable tactical response meant that Peterson’s 16 stab wounds were inflicted with scant active defence from security personnel, converting what could have been a serious incident into a life-threatening emergency necessitating hospitalisation.

The Expanded Context of Lanez’s Confinement

Tory Lanez’s current imprisonment originates from a high-profile shooting event in 2020 featuring fellow rapper Megan Thee Stallion. The altercation, which took place in the 2020 summer months, led to Peterson shooting Stallion in the foot. After a prolonged court proceedings, he was found guilty in December 2022 on several firearms charges, such as assault using a firearm, and subsequently sentenced to a decade in prison. This conviction marked a major turning point in hip-hop, drawing extensive press coverage and igniting substantial discussion within the music industry regarding responsibility and the circumstances surrounding the incident.

Peterson’s legal battles have continued throughout his incarceration, with his legal team mounting an appeal challenging the conviction and sentence. However, in November 2025, a panel of three judges rejected his appeal and maintained the 10-year sentence originally imposed, essentially shutting down what many anticipated as an avenue for release or sentence reduction. This rejection came roughly six months after the stabbing attack at Tehachapi, meaning Peterson was contending with both the psychological and physical aftermath of the prison attack whilst whilst also processing the disappointment of his unsuccessful appellate challenge. The convergence of these circumstances has substantially complicated his experience within the California prison system.

Lawful Claims and Compensation Requested

Tory Lanez’s court action against the California Department of Corrections pursues $100 million in financial restitution, representing one of the largest 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 asserts that systemic failures in correctional management and safety measures resulted in the severity of Peterson’s injuries during the stabbing incident in May 2025. The substantial compensation figure reflects both the physical injuries sustained and the emotional harm of the unprovoked attack.

At the heart of the lawsuit’s claims is the assertion that correctional officials made a dangerously inadequate choice in housing Peterson with fellow inmate Santino Casio, who was serving a life term for second-degree murder. The court documents asserts that the correctional department either was aware or ought to have recognised that this housing arrangement posed a serious danger to Peterson, especially given his prominent inmate status within the facility. Furthermore, the lawsuit challenges the actions of correctional staff, arguing that officers did not use proper emergency procedures such as flash grenades to halt Casio’s attack. Notably, Casio was never charged with the stabbing despite causing 16 injuries on Peterson.

• Department of Corrections did not stop identified high-risk inmate pairing
• Celebrity status made Peterson an identifiable target for attack
• Security personnel were slow to respond to stabbing incident
• Prison failed to employ flash grenades or other containment measures
• Peterson’s belongings, including unreleased songbooks, are unaccounted for
