This one is a doozy folks! Trigger warning for this episode as Mr. Kemper is a very twisted individual who did some unspeakable things to his victims. Ed murdered ten people, including his paternal grandparents and mother. He is noted for his large size (6 feet 9 inches) and for his high intellect, possessing an IQ of 145. Kemper was nicknamed the Co-ed Killer as the majority of his victims were female college students.
