Book excerpt: The third title in our Conversations with a Killer series focuses on one of the most notorious serial killers of the 1970s, Ed Kemper, a key character in the hit Netflix series Mindhunter. If there ever was a human monster that walked this earth, it was the highly intelligent, psychotic, 6’9” killer Edward “Big Ed” Kemper. As a troubled 15-year-old, Kemper shot and killed his grandparents. Eight years later, he went on an 11-month reign of terror slaughtering and dismembering six college co-eds in California, brutally killing his mother with a hammer, and breaking her best friend’s neck. Kemper, 71, remains alive at the California Medical Facility in Vacaville, more intimidating now than ever. Masterful crime writer Dary Matera tells Kemper’s full, shocking story, interweaving insights from the killer himself.
