Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has launched a $100 million lawsuit against California’s Correctional Department following a severe stabbing incident whilst imprisoned at the California Correctional Institute in Tehachapi last May. The artist, known as Daystar Peterson and currently serving a 10-year sentence 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 life-threatening attack.” The assault 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 facility warden, and guards as defendants, alleging carelessness regarding inmate placement and a slow reaction to the violence.

The May 2025 Attack and Its Aftermath

The May 2025 stabbing incident at Tehachapi represented 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 assault that left the rapper struggling to survive. Peterson sustained a collapsed lung alongside several stab injuries across his back, torso, and head—injuries serious enough to warrant immediate hospitalisation. The attack raised significant concerns about prison security protocols and classification systems for inmates, particularly given the dangerous situation of housing two inmates with such starkly different profiles and threat levels.

Following his recovery, Peterson was relocated to San Luis Obispo County’s California Men’s Colony, constituting another stage in his prison ordeal. The lawsuit additionally claims that during this transfer, Peterson failed to retrieve his belongings from Tehachapi, including songbooks featuring lyrics to unreleased music—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 shortcomings within the Department of Corrections.

• Casio attacked Peterson 16 times during the unprovoked assault
• 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

Claims of Negligence, and Institutional Failure

Housing Decisions and Security Worries

At the heart of Peterson’s lawsuit lies a core criticism of the Corrections Department’s decision process regarding inmate housing assignments. The legal filing contends that placing Peterson with Santino Casio—a life-sentence prisoner incarcerated for second-degree murder—represented a severe breakdown in risk evaluation and inmate classification. The lawsuit maintains that the department “ought to have been aware” to recognise the inherent risk in this pairing. Peterson’s prominent public profile, the suit maintains, rendered him an obvious target inside the correctional facility, rendering the accommodation choice not simply negligent but callously indifferent to his wellbeing and safety.

The lawsuit underscores that such accommodation determinations require careful consideration of detainee profiles, threat levels, and potential motivations for violence. By neglecting to isolate Peterson from Casio, facility management allegedly demonstrated a systemic disregard for core protective measures that ought to regulate California’s prison system. This failure of duty, the attorneys contends, substantially contributed to the environment where the stabbing happened, changing what could have stayed preventable violence into an wholly predictable consequence of institutional mismanagement and insufficient safety provisions.

Response and Guard Conduct

Beyond the initial housing decision, the lawsuit takes aim at correctional officers’ response during the incident of violence. According to the complaint, correctional officers failed to act promptly when Casio launched his attack, enabling the situation to worsen. The lawsuit directly challenges the failure to use flash grenades or other non-lethal intervention methods that might have stopped the attack before Peterson sustained his most severe injuries. This alleged slow reaction to an ongoing stabbing attack suggests either inadequate training, understaffing, or a troubling disregard for prisoner safety—each possibility casting doubt on institutional competence.

The guards’ actions during the crucial minutes of the attack raises questions about emergency procedures and personnel readiness within California’s prison system. Typical prison protocols typically mandate rapid response to acts of violence, yet the lawsuit contends this incident deviated significantly from such protocols. The aggregate consequence of sluggish reaction times and the failure to implement appropriate tactical intervention 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 Larger Context of Lanez’s Imprisonment

Tory Lanez’s ongoing incarceration originates from a widely publicized shooting event in 2020 involving fellow rapper Megan Thee Stallion. The confrontation, which took place in the summer of 2020, resulted in Peterson shooting Stallion in the foot. After a lengthy legal process, he was found guilty in December 2022 on several firearms charges, including assault using a firearm, and thereafter given a ten-year prison sentence. This conviction represented a major turning point in rap music, drawing widespread media attention and igniting substantial discussion across the music sector regarding responsibility and the events related to the occurrence.

Peterson’s ongoing litigation have persisted during his incarceration, with his defence counsel lodging an appeal contesting the conviction and sentence. However, in November 2025, a panel of three judges rejected his appeal and maintained the original 10-year sentence, essentially shutting down what many anticipated as an avenue for release or sentence reduction. This denial came about six months after the stabbing incident at Tehachapi, meaning Peterson was dealing with both the psychological and physical aftermath of the prison stabbing whilst simultaneously processing the frustration of his failed appellate challenge. The convergence of these circumstances has substantially complicated his situation in the California correctional system.

Legal Actions and Compensation Requested

Tory Lanez’s legal claim against the California Department of Corrections seeks $100 million in damages, constituting one of the most significant claims filed against the state’s correctional system in recent times. The lawsuit names the Department of Corrections as the principal defendant, alongside the warden and prison staff stationed at the California Correctional Institute in Tehachapi. The lawsuit contends that systemic failures in facility operations and security procedures led to the severity of Peterson’s injuries during the May 2025 stabbing incident. The large compensation amount reflects both the physical trauma sustained and the psychological impact of the unprovoked incident.

At the heart of the lawsuit’s claims is the assertion that correctional officials made a catastrophically poor choice in placing Peterson with fellow inmate Santino Casio, who was serving a life term for murder in the second degree. The court documents contends that the Department of Corrections either was aware or ought to have recognised that this cell assignment posed a significant risk to Peterson, particularly given his prominent inmate status within the facility. Furthermore, the lawsuit challenges the response of correctional staff, arguing that guards did not use proper emergency procedures such as flash grenades to stop Casio’s assault. Notably, Casio was not prosecuted with the assault despite causing sixteen wounds on Peterson.

• Department of Corrections did not stop identified high-risk inmate pairing
• Celebrity status rendered Peterson an identifiable target for attack
• Security personnel delayed response to stabbing incident
• Prison failed to employ flash grenades or alternative security measures
• Peterson’s personal possessions, such as unreleased songbooks, are unaccounted for
