Killer of Actress Stabbed in Prison:

The man convicted of stalking and killing actress Rebecca Schaeffer in 1989 was stabbed repeatedly by another inmate in the prison where he is serving a life sentence, corrections officials said.
. . .
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.

It also brought about the Driver's Privacy Protection Act, which is likely to be clobbered in what meaningful forms are left by Real ID, assuming it lives to become relevant. (Reno v. Condon)
