Rapper Sues California Prison System Over Stabbing Incident

Rapper Tory Lanez has launched a $100 million legal action against California’s Correctional Department following a brutal stabbing attack whilst imprisoned at the California Correctional Institute in Tehachapi in May. The artist, born Daystar Peterson and presently completing a 10-year prison term for the 2020 shooting of Megan Thee Stallion, was struck 16 times with a blade by prison inmate Santino Casio in what the lawsuit characterises as an “unprovoked life-threatening attack.” The assault left Peterson admitted to hospital with a collapsed 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 delayed response 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 second-degree murder, launched an unprovoked assault that left the rapper struggling to survive. Peterson sustained a punctured lung alongside several stab injuries across his back, torso, and head—injuries severe enough to warrant emergency hospitalisation. The attack raised serious questions about security procedures in prisons and classification systems for inmates, particularly given the dangerous situation of housing two inmates with such starkly different profiles and threat levels.

Following his return to health, Peterson was moved to San Luis Obispo County’s California Men’s Colony, constituting another stage in his time in custody. The lawsuit further contends that during this transfer, Peterson never recovered his belongings from Tehachapi, including songbooks with lyrics to unpublished songs—a loss that intensifies the emotional and physical suffering of the attack. Notably, despite the gravity of the incident, Casio was not prosecuted in connection with the assault, a detail the lawsuit highlights 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 numerous injuries
• Transferred to California Men’s Colony after recovery
• Personal items, including songbooks, not recovered from Tehachapi

Accusations of Negligence, and Systemic Failure

Accommodation Choices and Security Worries

At the core of Peterson’s lawsuit sits a core challenge of the Corrections Department’s decision-making concerning prisoner accommodation placements. The court document argues that placing Peterson with Santino Casio—a lifer serving time for second-degree murder—constituted a catastrophic failure in risk evaluation and prisoner classification. The lawsuit argues 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 contends, made him an obvious target inside the correctional facility, making the housing decision not merely negligent but recklessly indifferent to his wellbeing and safety.

The lawsuit underscores that such housing decisions require careful consideration of inmate backgrounds, risk assessments, and possible drivers for violence. By failing to separate Peterson from Casio, facility management allegedly demonstrated a institutional indifference for core protective measures that must oversee California’s correctional facilities. This failure of duty, the legal team maintains, immediately caused the circumstances in which the stabbing took place, changing what could have stayed preventable violence into an wholly predictable consequence of institutional mismanagement and insufficient safety provisions.

Response and Guard Behaviour

Beyond the initial housing decision, the lawsuit takes aim at correctional officers’ response during the incident of violence. According to the filing, correctional officers were slow to intervene when Casio initiated the assault, enabling the situation to worsen. The lawsuit explicitly condemns the failure to employ flash grenades or other non-lethal intervention methods that might have prevented further violence before Peterson incurred his most critical harm. This alleged slow reaction to an ongoing stabbing attack suggests either poor preparation, understaffing, or a troubling disregard for prisoner safety—each possibility undermining institutional competence.

The guards’ behaviour during the crucial minutes of the attack calls into question emergency procedures and staff preparedness within California’s prison system. Typical prison protocols ordinarily stipulate swift action to acts of violence, yet the lawsuit contends this incident departed substantially from such protocols. The combined impact of sluggish reaction times and the absence of 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 grave occurrence into a life-threatening emergency demanding hospital treatment.

The Wider Context of Lanez’s Confinement

Tory Lanez’s ongoing incarceration originates from a widely publicized 2020 shooting incident involving fellow rapper Megan Thee Stallion. The altercation, which occurred during the summer of 2020, led to Peterson shooting Stallion in her foot. Following a prolonged court proceedings, he was convicted in December 2022 on several firearms charges, such as assault using a firearm, and subsequently given a decade in prison. This conviction represented a significant moment in rap music, attracting widespread media attention and igniting substantial discussion within the music industry concerning accountability and the events related to the incident.

Peterson’s legal battles have continued throughout his incarceration, with his legal team filing an appeal contesting the conviction and sentence. However, in November 2025, a three-judge panel denied his appeal and confirmed the original 10-year sentence, essentially shutting down what many anticipated as an avenue for release or reduction in sentence. This rejection came approximately six months after the stabbing attack at Tehachapi, meaning Peterson was contending with both the physical and psychological aftermath of the prison attack whilst at the same time dealing with the frustration of his unsuccessful appeal. The confluence of these events has markedly worsened his situation in the California correctional system.

Lawful Claims and Compensation Requested

Tory Lanez’s court action against the California Department of Corrections seeks $100 million in financial restitution, representing one of the most substantial claims filed against the state’s correctional system in the past several years. The lawsuit names the Department of Corrections as the main defendant, alongside the warden and individual guards stationed at the California Correctional Institute in Tehachapi. The lawsuit contends that systemic failures in facility operations and safety measures resulted in the severity 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 assault.

At the heart of the lawsuit’s claims is the allegation that prison authorities made a dangerously inadequate decision in housing Peterson with cellmate Santino Casio, who was serving a life sentence for murder in the second degree. The court documents asserts that the correctional department either knew or ought to have recognised 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 response of correctional staff, contending that guards did not use proper emergency procedures such as stun grenades to stop Casio’s attack. Notably, Casio was never charged with the stabbing despite inflicting 16 injuries on Peterson.

• Department of Corrections did not stop known dangerous inmate pairing
• Celebrity status rendered Peterson an identifiable target for attack
• Security personnel were slow to respond to stabbing emergency
• Prison did not use flash grenades or alternative security measures
• Peterson’s belongings, including unreleased songbooks, remain missing
