Kenneth McDuff was sentenced to death row not once, but twice. This Texas serial killer is known for the rape and brutal murder of Edna Sullivan. He broke her neck using a broomstick. He was sentenced to death in 1968. However, the death penalty was overturned in 1972, causing his sentence to be commuted to life.
Then, overcrowding in the prison allowed for his release. This led to the deaths of at least six more young women and a capital murder conviction that got him his second death sentence. He died in 1998 by lethal injection.
