Rapper Sues California Prison System Over Stabbing Incident

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

The May 2025 Attack 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 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 several stab injuries across his back, torso, and head—injuries serious enough to warrant emergency hospitalisation. The attack raised significant concerns 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 recuperation, Peterson was transferred to San Luis Obispo County’s California Men’s Colony, representing another phase in his prison ordeal. The lawsuit additionally claims that during this move, Peterson did not regain his belongings from Tehachapi, including songbooks containing lyrics to unreleased music—a loss that exacerbates the physical and emotional trauma of the assault. Notably, despite the gravity of the incident, Casio was not held accountable in connection with the stabbing, a detail the lawsuit highlights as part of systemic failures within the correctional system.

• Casio attacked Peterson 16 times during the unprovoked assault
• Peterson hospitalised with punctured lung and several lacerations
• Moved to California Men’s Colony upon recovery
• Personal belongings, including songbooks, not recovered from Tehachapi

Claims of Negligence, and Systemic Failure

Accommodation Choices and Security Worries

At the heart of Peterson’s lawsuit lies a fundamental challenge of the Corrections Department’s decision-making concerning prisoner accommodation placements. The legal filing contends that housing Peterson alongside 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 danger inherent in this arrangement. Peterson’s high-profile celebrity status, the suit contends, rendered him an clear target inside the correctional environment, making the housing decision not merely negligent but callously indifferent to his safety and wellbeing.

The lawsuit underscores that such housing decisions require careful consideration of detainee profiles, security classifications, and possible drivers for violence. By not segregating Peterson from Casio, correctional officials purportedly showed a widespread neglect for basic safety protocols that ought to regulate California’s detention centres. This negligence, the legal team argues, substantially contributed to the conditions under which the stabbing occurred, changing what could have stayed preventable violence into an wholly predictable consequence of organisational negligence and inadequate protective measures.

Response and Guard Conduct

Beyond the initial housing decision, the lawsuit challenges prison guards’ response during the incident of violence. According to the filing, correctional officers were slow to intervene when Casio carried out his attack, enabling the situation to worsen. The lawsuit explicitly condemns the failure to use flash grenades or other non-lethal intervention methods that might have prevented further violence before Peterson suffered his worst injuries. This alleged sluggishness in responding to an ongoing stabbing attack suggests either poor preparation, inadequate staffing, or a troubling indifference to inmate welfare—each possibility casting doubt on institutional competence.

The guards’ behaviour during the critical minutes of the attack calls into question emergency procedures and personnel readiness within California’s prison system. Standard correctional procedures typically mandate swift action to acts of violence, yet the lawsuit indicates this incident significantly departed from such protocols. The aggregate consequence of delayed responses and the failure to implement 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 significant event into a critical emergency requiring hospitalisation.

The Larger Context of Lanez’s Confinement

Tory Lanez’s current imprisonment stems from a widely publicized 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. Following a lengthy legal process, 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 guilty verdict represented a major turning point in rap music, drawing widespread media attention and sparking substantial discussion within the music industry concerning accountability and the circumstances surrounding the incident.

Peterson’s legal battles have persisted during his incarceration, with his attorneys filing an appeal contesting the conviction and sentence. However, in November 2025, a three-judge panel rejected his appeal and upheld the original 10-year sentence, effectively closing what many hoped would be an route to freedom or sentence reduction. This denial came about six months after the stabbing incident at Tehachapi, meaning Peterson was dealing with both the physical and psychological aftermath of the prison attack whilst whilst also processing the frustration of his unsuccessful appeal. The convergence of these circumstances has significantly complicated his experience within the California correctional system.

Legal Claims and Damages Claimed

Tory Lanez’s lawsuit against the California Department of Corrections seeks $100 million in compensation, amounting to 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 primary defendant, in addition to the warden and individual guards stationed at the California Correctional Institute in Tehachapi. The lawsuit argues that institutional failures in correctional management and security protocols led to the extent of Peterson’s injuries during the stabbing incident in May 2025. The substantial compensation figure reflects both the physical trauma sustained and the emotional harm of the unprovoked assault.

At the heart of the lawsuit’s arguments is the allegation that correctional officials made a dangerously inadequate decision in placing Peterson with cellmate 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 should have known that this cell assignment posed a serious danger to Peterson, particularly given his high-profile celebrity status within the facility. Furthermore, the lawsuit challenges the actions of correctional staff, contending that officers did not use proper emergency procedures such as flash grenades to halt Casio’s assault. Notably, Casio was never charged with the assault despite causing sixteen wounds on Peterson.

• Correctional Department failed to prevent known dangerous inmate pairing
• Celebrity status made Peterson an identifiable target for attack
• Security personnel delayed response to stabbing incident
• Prison did not use flash grenades or alternative security measures
• Peterson’s personal possessions, including unreleased songbooks, are unaccounted for
