Tanya Kramer was an elderly woman who was killed by Wally Forton.
Wally showed up at Tanya's house and demanded to get inside, presumably to go see Melissa. Tanya didn't open up the door and instead called the cops. About 40 or so minutes later, he came back to her house and broke in, killing Tanya and her sister Violet with a meat tenderizer. Wally panicked and tried to dispose of the body down the garbage disposal, burning out the motor.
Tanya and her sister's deaths would later spark a riot and lead to a revolt against several LAPD officers.
