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 artist, 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 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 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 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 completing a life sentence for murder in the second degree, launched an unprovoked attack that left the rapper fighting for his life. Peterson sustained a punctured lung alongside several stab injuries across his back, torso, and head—injuries serious enough to warrant immediate 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 prison ordeal. The lawsuit further alleges that during this transfer, Peterson failed to retrieve his personal possessions from Tehachapi, including songbooks with lyrics to unpublished songs—a loss that intensifies the psychological and physical harm of the assault. Notably, despite the severity of the attack, Casio was not held accountable in connection with the knife attack, a detail the lawsuit emphasises as part of systemic shortcomings within the prison service.

• Casio stabbed Peterson 16 times during the unprovoked assault
• Peterson taken to hospital with collapsed lung and several lacerations
• Relocated to California Men’s Colony after recovery
• Personal possessions, including songbooks, not recovered from Tehachapi

Accusations of Negligence and Institutional Failure

Housing Options and Security Worries

At the heart of Peterson’s lawsuit sits a core criticism of the Corrections Department’s decision process concerning inmate housing assignments. The court document contends that placing Peterson with Santino Casio—a life-sentence prisoner incarcerated for murder in the second degree—constituted a severe breakdown in risk assessment and inmate classification. The lawsuit argues that the department “ought to have been aware” to recognise the danger inherent in this pairing. Peterson’s high-profile celebrity profile, the suit contends, rendered him an obvious target inside the correctional environment, making the housing decision not simply negligent but recklessly indifferent to his safety and wellbeing.

The lawsuit emphasises that such placement choices require careful consideration of prisoner histories, security classifications, and underlying reasons for violence. By not segregating Peterson from Casio, prison administrators reportedly displayed a institutional indifference for fundamental security procedures that must oversee California’s prison system. This breach of care, the legal team argues, substantially contributed to the conditions under which the stabbing occurred, transforming what should have been preventable violence into an entirely foreseeable consequence of institutional mismanagement and substandard security arrangements.

Response and Guard Conduct

Beyond the primary accommodation decision, the lawsuit takes aim at prison guards’ response during the incident of violence. According to the filing, correctional officers failed to act promptly when Casio initiated the assault, enabling the situation to worsen. The lawsuit specifically criticises the failure to deploy non-lethal devices or other non-lethal intervention methods that might have stopped the attack before Peterson sustained his most severe injuries. This alleged sluggishness in responding to an active stabbing incident suggests either insufficient training, insufficient staffing, or a troubling neglect of inmate wellbeing—each possibility undermining institutional competence.

The guards’ actions during the crucial minutes of the attack prompts inquiry into emergency procedures and personnel readiness within California’s prison system. Standard correctional procedures generally require immediate intervention to acts of violence, yet the lawsuit indicates this incident deviated significantly from such protocols. The cumulative effect of delayed responses and the failure to implement appropriate tactical intervention 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 situation requiring hospitalisation.

The Wider Context of Lanez’s Incarceration

Tory Lanez’s current imprisonment stems from a widely publicized shooting event in 2020 involving rap artist Megan Thee Stallion. The altercation, which took place in the summer of 2020, resulted in Peterson shooting Stallion in her foot. After a prolonged court proceedings, he was convicted in December 2022 on multiple gun-related charges, such as assault using a firearm, and thereafter sentenced to a decade in prison. This guilty verdict marked a significant moment in hip-hop, drawing extensive press coverage and igniting considerable debate across the music sector concerning responsibility and the circumstances surrounding the occurrence.

Peterson’s court disputes have continued throughout his incarceration, with his legal team filing an appeal contesting the conviction and sentence. However, in November 2025, a panel of three judges rejected his appeal and confirmed the 10-year sentence originally imposed, essentially shutting down what many hoped would be an route to freedom or reduction in sentence. This rejection came about six months after the stabbing attack at Tehachapi, meaning Peterson was contending with both the psychological and physical aftermath of the prison attack whilst at the same time dealing with the frustration of his unsuccessful appeal. The confluence of these events has substantially complicated his circumstances within the California correctional system.

Legal Actions and Compensation Sought

Tory Lanez’s legal claim against the California Department of Corrections seeks $100 million in financial restitution, representing one of the largest suits filed against the state’s correctional system in the past several years. The court filing names the Department of Corrections as the principal defendant, in addition to the warden and individual guards stationed at the California Correctional Institute in Tehachapi. The lawsuit argues that widespread deficiencies in prison management and safety measures resulted in the seriousness of Peterson’s injuries during the stabbing incident in May 2025. The large compensation amount reflects both the physical trauma sustained and the psychological impact 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 cellmate Santino Casio, who was completing a life term for second-degree murder. The court documents asserts that the Department of Corrections either knew or ought to have recognised that this housing arrangement posed a significant risk to Peterson, especially given his high-profile celebrity status within the prison. Furthermore, the lawsuit challenges the response of security personnel, contending that officers did not use proper emergency procedures such as stun grenades to halt Casio’s assault. Notably, Casio was never charged with the stabbing despite inflicting sixteen wounds on Peterson.

• Department of Corrections did not stop identified high-risk inmate pairing
• Celebrity status rendered Peterson a recognisable target for violence
• Security personnel were slow to respond to stabbing emergency
• Prison failed to employ flash grenades or other containment measures
• Peterson’s personal possessions, including unreleased songbooks, are unaccounted for
