The most famous serial killer (Ted Bundy), who may have killed 40 women, was only convicted because of an odontologist's being able to match his teeth with a bite mark on a victim in Florida. In the home of a Canadian serial rapist-turned-killer, tiny trace evidence was found. Videotapes convicted him, but his wife's participation in torture and sexual abuse was ignored because she turned state's evidence for a 12-year sentence before the tapes were found. A single bloody palm print led to the female serial killer Aileen Wuornos, who confessed to killing six middle-aged men.
