Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has filed a $100 million lawsuit against California’s Correctional Department after a severe stabbing incident whilst incarcerated at the California Correctional Institute in Tehachapi in May. The artist, known as Daystar Peterson and presently completing a 10-year prison term for the 2020 shooting incident involving Megan Thee Stallion, was struck 16 times with a blade by fellow inmate Santino Casio in what the lawsuit describes as an “unprovoked life-threatening attack.” The attack left Peterson admitted to hospital 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 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 murder in the second degree, launched an unprovoked attack that left the rapper fighting for his life. 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 inmate classification procedures, particularly given the dangerous situation of housing two inmates with such starkly different profiles and threat levels.

Following his recovery, Peterson was transferred to San Luis Obispo County’s California Men’s Colony, representing another phase in his incarceration experience. The lawsuit further contends that during this relocation, Peterson failed to retrieve his personal items from Tehachapi, including songbooks featuring lyrics to unreleased music—a loss that intensifies the psychological and physical harm of the incident. Notably, despite the severity of the attack, Casio was not charged in connection with the stabbing, a detail the lawsuit underscores as part of institutional breakdowns within the correctional system.

• Casio struck Peterson 16 times during the unprovoked incident
• Peterson taken to hospital with punctured lung and several lacerations
• Transferred to California Men’s Colony after recovery
• Personal belongings, including songbooks, never recovered from Tehachapi

Claims of Negligence, and Systemic Failure

Housing Decisions and Safety Issues

At the heart of Peterson’s lawsuit sits a fundamental criticism of the Corrections Department’s decision process concerning inmate housing assignments. The court document 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 “knew or should have been known” to recognise the danger inherent in this pairing. Peterson’s high-profile celebrity profile, the suit maintains, made him an clear target inside the correctional facility, making the accommodation choice not simply negligent but recklessly indifferent to his wellbeing and safety.

The lawsuit underscores that such accommodation determinations necessitate close examination of prisoner histories, risk assessments, and potential motivations for violence. By not segregating Peterson from Casio, correctional officials allegedly demonstrated a systemic disregard for basic safety protocols that must oversee California’s detention centres. This negligence, the attorneys argues, substantially contributed to the circumstances in which the stabbing occurred, changing what could have stayed preventable violence into an entirely foreseeable consequence of systemic failure and substandard security arrangements.

Response and Security Conduct

Beyond the initial housing decision, the lawsuit targets prison guards’ response during the actual assault. According to the complaint, correctional officers delayed their intervention when Casio launched his attack, allowing the violence to escalate unchecked. The lawsuit explicitly condemns the failure to use flash grenades or other non-lethal tactical measures 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, understaffing, or a troubling indifference to inmate welfare—each possibility casting doubt on institutional competence.

The guards’ behaviour during the critical minutes of the attack raises questions about emergency protocols and staff preparedness within California’s prison system. Standard correctional procedures generally require swift action to violent incidents, yet the lawsuit contends this incident deviated significantly from such protocols. The combined impact of delayed responses and the failure to implement proper tactical measures meant that Peterson’s 16 stab wounds were inflicted with little active opposition from security personnel, transforming what could have been a grave occurrence into a life-threatening emergency necessitating hospitalisation.

The Wider Context of Lanez’s Incarceration

Tory Lanez’s current imprisonment originates from a widely publicized shooting event in 2020 featuring rap artist Megan Thee Stallion. The confrontation, which occurred during the summer of 2020, resulted in Peterson shooting Stallion in her foot. After a prolonged court proceedings, he was found guilty in December 2022 on multiple gun-related charges, such as assault using a firearm, and subsequently given a ten-year prison sentence. This conviction represented a major turning point in rap music, attracting extensive press coverage and igniting substantial discussion across the music sector regarding accountability and the events related to the incident.

Peterson’s ongoing litigation have continued throughout his incarceration, with his legal team lodging an appeal challenging the conviction and sentence. However, in November 2025, a three-judge panel rejected his appeal and maintained the 10-year sentence originally imposed, effectively closing what many anticipated as an avenue for release or reduction in sentence. This denial came approximately six months after the stabbing incident at Tehachapi, meaning Peterson was contending with both the physical and psychological aftermath of the prison stabbing whilst at the same time dealing with the frustration of his unsuccessful appellate challenge. The confluence of these events has markedly worsened his experience within the California correctional system.

Legal Actions and Damages Claimed

Tory Lanez’s court action against the California Department of Corrections demands $100 million in financial restitution, amounting to one of the most significant cases filed against the state’s correctional system in recent times. The court filing names the Department of Corrections as the principal defendant, together with the warden and correctional officers stationed at the California Correctional Institute in Tehachapi. The lawsuit contends that institutional failures in facility operations and security protocols resulted in the seriousness of Peterson’s injuries during the May 2025 stabbing incident. The large compensation amount reflects both the physical injuries sustained and the psychological impact of the unprovoked assault.

Central to the lawsuit’s claims is the allegation that prison authorities made a catastrophically poor decision in housing Peterson with fellow inmate Santino Casio, who was serving a life sentence for murder in the second degree. The legal filing asserts that the Department of Corrections either knew or ought to have recognised that this housing arrangement posed a serious danger to Peterson, especially given his high-profile celebrity status within the prison. Furthermore, the lawsuit challenges the response of correctional staff, arguing that guards failed to employ appropriate emergency measures such as stun grenades to stop Casio’s attack. Notably, Casio was never charged with the assault despite causing sixteen wounds on Peterson.
