Mommy Dearest
In 1984, Elizabeth Diane Downs was sentenced to life in prison after being convicted for the shooting and attempted murder of her three young children. One of them died after what she did. At the time this all took place, Downs told police that some guy attempted to carjack them and took out a gun. Of course, that was quickly proven to be a lie.

Downs managed to escape prison in 1987, and she was on the run for a brief time before getting recaptured. She deserves to rot and die in there.
