Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has launched a $100 million lawsuit against California’s Correctional Department after a brutal stabbing attack 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 characterises as an “unprovoked life-threatening attack.” The attack left Peterson hospitalised with a punctured lung and multiple stab wounds 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 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 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 multiple stab wounds across his back, torso, and head—injuries severe enough to warrant emergency hospitalisation. The attack raised significant concerns about security procedures in prisons and classification systems for inmates, particularly given the volatile circumstances of housing two inmates with such starkly different profiles and threat levels.

Following his recuperation, Peterson was relocated to San Luis Obispo County’s California Men’s Colony, representing another phase in his time in custody. The lawsuit further alleges that during this transfer, Peterson never recovered his personal possessions from Tehachapi, including songbooks with lyrics to unreleased music—a loss that intensifies the psychological and physical harm of the incident. Notably, despite the seriousness of the assault, Casio was not prosecuted in connection with the assault, a detail the lawsuit underscores as part of systemic shortcomings within the correctional system.

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

Claims of Negligence, and Systemic Failure

Housing Options and Security Worries

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

The lawsuit underscores that such accommodation determinations necessitate close examination of detainee profiles, security classifications, and possible drivers for violence. By neglecting to isolate Peterson from Casio, facility management reportedly displayed a institutional indifference for core protective measures that must oversee California’s detention centres. This negligence, the counsel contends, immediately caused the conditions under which the stabbing happened, changing what could have stayed preventable violence into an wholly predictable consequence of organisational negligence and inadequate protective measures.

Response and Guard Behaviour

Beyond the primary accommodation decision, the lawsuit targets prison guards’ response during the incident of violence. According to the complaint, correctional officers were slow to intervene when Casio initiated the assault, 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 stopped the attack before Peterson incurred his most critical harm. This alleged delay in response to an ongoing stabbing attack suggests either insufficient training, inadequate staffing, or a troubling neglect of inmate wellbeing—each possibility undermining institutional competence.

The guards’ actions during the critical 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 suggests this incident departed substantially from such protocols. The combined impact of slow response times and the failure to implement suitable tactical response meant that Peterson’s 16 stab wounds were inflicted with little active opposition from security personnel, transforming what could have been a serious incident into a life-threatening emergency demanding hospital treatment.

The Larger Context of Lanez’s Imprisonment

Tory Lanez’s current imprisonment originates from a high-profile 2020 shooting incident featuring rap artist Megan Thee Stallion. The confrontation, which took place in the summer of 2020, led to Peterson shooting Stallion in her foot. After a prolonged court proceedings, he was found guilty in December 2022 on multiple gun-related charges, including assault using a firearm, and thereafter sentenced to a ten-year prison sentence. This conviction represented a significant moment in hip-hop, drawing widespread media attention and sparking considerable debate within the music industry concerning accountability and the circumstances surrounding the occurrence.

Peterson’s ongoing litigation have continued throughout his incarceration, with his legal team mounting an appeal contesting the conviction and sentence. However, in November 2025, a panel of three judges denied his appeal and upheld the original 10-year sentence, effectively closing what many hoped would be an route to freedom or reduction in sentence. This rejection came about six months after the stabbing incident at Tehachapi, meaning Peterson was grappling with both the physical and psychological aftermath of the prison attack whilst whilst also processing the disappointment of his failed appellate challenge. The combination of these events has significantly complicated his experience within the California prison system.

Legal Actions and Compensation Sought

Tory Lanez’s court action against the California Department of Corrections seeks $100 million in compensation, constituting one of the most substantial cases filed against the state’s correctional system in recent times. The court filing names the Department of Corrections as the main defendant, in addition to the warden and individual guards stationed at the California Correctional Institute in Tehachapi. The lawsuit contends that widespread deficiencies in prison management and security protocols resulted in the extent of Peterson’s injuries during the stabbing incident in May 2025. The significant financial award reflects both the physical trauma sustained and the mental distress of the unprovoked assault.

At the heart of the lawsuit’s arguments is the assertion that prison authorities made a catastrophically poor choice in housing Peterson with cellmate Santino Casio, who was serving a life sentence for second-degree murder. The court documents asserts that the correctional department either knew or should have known that this cell assignment posed a serious danger to Peterson, particularly given his high-profile celebrity standing within the facility. Furthermore, the lawsuit challenges the response of correctional staff, contending that guards did not use proper emergency procedures such as stun grenades to halt Casio’s assault. Notably, Casio was never charged with the stabbing 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 delayed response to stabbing emergency
• Prison failed to employ flash grenades or other containment measures
• Peterson’s belongings, such as unreleased songbooks, are unaccounted for
