Elizabeth Diane Downs (née Frederickson, born August 7, 1955) is an American woman who murdered her daughter and attempted to murder her other two children near Springfield, Oregon, on May 19, 1983. Following the crimes, she made claims to police that a man had attempted to carjack her and had shot the children. She was convicted in 1984 and sentenced to life in prison with the possibility of parole after twenty-five years. She briefly escaped in 1987 but was quickly recaptured. Downs has been repeatedly denied parole and psychiatrists have diagnosed her with narcissistic, histrionic and antisocial personality disorders, with one labelling her as a "deviant sociopath".
