Rebecca Lucile Schaeffer (November 6, 1967 – July 18, 1989) was an American actress best known for her role in the sitcom My Sister Sam. Schaeffer was stalked and then murdered by Robert John Bardo, prompting the passage of anti-stalking laws in California.
Robert Bardo has had a long history of stalking young celebrities. In 1986, he became fixated on Rebecca Schaeffer, star of the hit sitcom My Sister Sam. Three years later, in July of 1989, Bardo used a private investigator to locate Schaeffer's home address, then showed up at her apartment. Schaeffer politely signed an autograph for Bardo, but when he returned, she asked him to leave, which enraged him. He then shot her in the chest. She was dead by the time the police arrived.
