A Life-Threatening Attack Inside Prison Walls
Daystar Peterson, better known as Tory Lanez, was attacked during what should have been an ordinary day in the prison yard. The 33-year-old Canadian rapper encountered Santino Casio, who stabbed him 16 times using a homemade shank. Lanez collapsed with severe injuries to his back, torso, head, and face, eventually suffering two collapsed lungs. He required immediate airlifting to a hospital where he was placed on a ventilator. The assault left permanent facial scarring, detailed court records show. After discharge, Lanez was transferred to California Men’s Colony in San Luis Obispo County for his remaining sentence.
Who Is Santino Casio and Why Was He Housed With Lanez
The lawsuit’s central claim is devastating, prison officials knowingly housed Lanez with Casio despite clear danger signs. Casio, 41, has been serving a life sentence for second-degree murder and first-degree attempted murder. His prison record reveals a pattern of violence. In 2008, he received additional sentencing for assaulting a prisoner with a deadly weapon. By 2018, he was convicted of manufacturing a deadly weapon while incarcerated. These convictions were in the prison system’s records. Despite this, officials allegedly placed Lanez in the same housing unit as this maximum-security prisoner.

| Factor | Details |
| Inmate | Santino Casio, age 41 |
| Current Sentence | Life for murder and attempted murder |
| Prior Violent Offenses | 2008 assault with deadly weapon, 2018 manufacturing deadly weapon |
| Weapon Used | Homemade shank |
The lawsuit argues that Casio’s history made him exceptionally dangerous. Despite protocols designed to separate high-risk inmates from vulnerable prisoners, officials allegedly ignored these guidelines. Lanez’s celebrity status made him an even more obvious target. Court documents state Lanez should have been immediately recognized as someone needing protective measures.
Negligent Response and Missing Security Measures
Beyond the housing decision, Lanez’s legal team claims prison staff response was dangerously slow. When the attack unfolded, correctional officers were not present right away. The lawsuit states flash grenades or smoke bombs should have been deployed to stop Casio immediately, but these weren’t used. Investigators question why the response was delayed, allowing a full attack to occur. This delay converted what could have been a minor incident into a life-threatening trauma. Lanez was airlifted due to the severity of his wounds. The California Department of Corrections spokesperson declined comment, citing pending litigation.
“The choice to house Casio with Peterson was known or should have been a known danger.”

Beyond Physical Harm, Stolen Intellectual Property
The lawsuit goes further than just the stabbing. Lanez claims prison officials illegally seized his songbooks containing unpublished original lyrics with substantial commercial value while he was hospitalized. These documents remain in state custody. In a June 2025 grievance letter, Lanez stated prison staff constantly used tactics to exploit him. He alleged the attack could have been an attempt to steal his intellectual property worth millions of dollars. The lawsuit demands immediate return of all songbooks and compensation for their loss. This claim adds another layer to allegations of institutional negligence.
What’s Next for Tory Lanez and the California Prison System
The $100 million lawsuit represents one of California’s largest prison negligence claims. Lanez is currently incarcerated at California Men’s Colony, completing his 10-year sentence for the 2020 Megan Thee Stallion shooting. This new lawsuit adds significant legal pressure on the state’s corrections system. Will officials face accountability for the housing decision, delayed response, and missing security protocols? The case raises critical questions about how prisons treat high-profile inmates and whether adequate safety measures truly exist. As litigation unfolds, expect this case to influence future prison safety standards across California. What lessons learned can prevent similar tragedies in the future?
