Rapper Tory Lanez has sued the California prison system, saying he never should have been housed with a fellow inmate who stabbed him 16 times last year.
Lanez, 33, whose legal name is Daystar Peterson, filed the federal lawsuit seeking $100 million in damages on Tuesday against the California Department of Corrections and Rehabilitation and the warden and guards at the prison in Tehachapi where he was being held.
The suit says he was stabbed 16 times in the back, torso, head and face in an “unprovoked life-threatening attack” by inmate Santino Casio, who used a homemade “shank.” Lanez had a collapsed lung and had to be airlifted to a hospital, it says.
Lanez is serving a 10-year sentence for shooting hip-hop star Megan Thee Stallion in the feet after a dramatic and high-profile 2022 trial in Los Angeles.
Prison officials say he was attacked May 12, 2025, by Casio, who is serving a life sentence for second-degree murder and first-degree attempted murder. Casio had another 2008 conviction for assault by a prisoner with a deadly weapon and another in 2018 for manufacturing a deadly weapon.
“The choice to house Casio with Peterson was known or should have been a known danger,” the lawsuit says. It alleges that correctional officers’ response was slow, and no special measures like flash grenades or smoke bombs were used to stop Casio. It says the institution housed the men together despite the rapper’s “high-profile celebrity status,” which made him a target.
There is no record of Casio being charged in the assault. An attorney who represented him previously did not respond to messages seeking comment at the time.
Lanez was transferred to another prison, the California Men’s Colony, in San Luis Obispo County.
The lawsuit also says the defendants unlawfully seized his songbooks with unpublished lyrics that are of great future commercial value and refused to return them.
In response to a request for comment, Department of Corrections spokesperson Ike Dodson said the agency does not comment on pending litigation.
The lawsuit was first reported by TMZ.
Lanez was convicted of three felonies in December 2022: assault with a semiautomatic firearm; having a loaded, unregistered firearm in a vehicle; and discharging a firearm with gross negligence.
A California court rejected his appeal in November.
Megan, whose legal name is Megan Pete, testified at trial that in July 2020, after they left a party at Kylie Jenner’s Hollywood Hills home, Lanez fired the gun at the back of her feet and shouted for her to dance as she walked away from an SUV in which they had been riding.
She had bullet fragments surgically removed from both feet. It was not until months after the incident that she publicly identified Lanez as the person who fired the gun.
The 32-year-old Canadian Lanez began releasing mixtapes in 2009 and saw a steady rise in popularity, moving on to major label albums, two of which reached the top 10 on Billboard’s charts.
