Robert John Bardo, 37, suffered 11 stab and puncture wounds Friday at Mule Creek State Prison in Amador County, authorities said. He was treated at University of California, Davis, Medical Center and returned to the prison, officials said.
"We have a number of high-notoriety cases, so we cannot jump to the conclusion as to whether his notoriety was a factor in the attack," said prison Sgt. Chris Weathersbee.
The slaying of Schaeffer, a former teenage model who co-starred in the 1980s sitcom "My Sister Sam," helped prompt anti-stalking laws. She was shot when she answered the door of her home in Los Angeles.
According to trial testimony, Bardo, then 19, was obsessed with Schaeffer, and sent her letters and tried to visit her. He obtained her address through a private detective, who got it from the state Department of Motor Vehicles.
Bardo was housed in a maximum-security unit for inmates with sensitive needs, including former gang members, notorious prisoners and those convicted of sex crimes.
State Department of Corrections and Rehabilitation officials said he was stabbed in the prison yard while inmates were on their way to breakfast. Two inmate-made weapons were found at the scene. The suspect in the attack was identified as a man serving an 82-years-to-life sentence for second-degree murder.
