Stalker Who Killed 'My Sister Sam Actress' Stabbed in Prison

A man convicted of killing a popular 1980s actress was stabbed in prison by a fellow inmate Friday.

Authorities said Robert Bardo suffered 11 stab and puncture wounds at California's Mule Creek State Prison. He was treated and returned to the prison.

Bardo was convicted of stalking and killing Rebecca Schaeffer, a teen-age model who co-starred in the sitcom "My Sister Sam." Bardo shot Schaeffer in 1989 after she answered the door at her Los Angeles home.

According to trial testimony, Bardo got Schaeffer's address through a private detective, who retrieved it from Department of Motor Vehicles records. The crime helped prompt anti-stalking laws.

The suspect in Friday's attack was identified as a man serving an 82-years-to-life sentence for second-degree murder.
