it was a movie i watched on usa up all night when i was about 9 years old but it was about a blond chic and she was trying to get married or something but everybody she marries or sleeps with she ends up killing them i think her name was bunny or something and i think her family were bank robberws but im not actually sure
Is it I Married an Axe Murderer?
Maybe the "Goldi Lox" segment of "Deadtime Stories?"
