Elizabeth Diane Frederickson Downs (born August 7, 1955) is an American convicted murderer. In May 1983, she shot her three children, killing one and seriously wounding two. Downs then told police a stranger had attempted to carjack her and had shot the children. She was convicted in 1984 and sentenced to life in prison.
Diane's motive was simply to free herself of parenthood so she could pursue a romantic relationship with a man who didn't want children. She chose to murder them instead of giving full-custody to her husband.
Prior to her arrest and trial, Downs became pregnant with a fourth child, a daughter she named Amy.
