Who is Ed Kemper aka the Co-ed Killer in Mindhunter?

With Mindhunter returning to Netflix people are asking who is Ed Kemper aka the Co-ed Killer.

Here are 5 things you might not know about the giant serial killer -

1. Kemper is a giant at 6foot 9 and was teased about it at school and by his family including his elder sister who allegedly tried to push him in front of a train and also tried to drown him.

2. His mother Clarnell Elizabeth Kemper was an alcoholic drunk who despised her son. He later killed her.

3. When he was a child he already showed signs of being a serial killer. He would decapitate his sister's dolls, torture and kill animals and ask his sister to play an electric chair game where she'd pretend to electrocute him.

4. He's called the Co-ed Killer because most of his victims were young women students at co-educational establishments. He targeted them when they were hitchhiking and would drive them to secluded spots where he'd decapitate, dismember and violate them.

5. When he was 15 he murdered his grandparents and was diagnosed as paranoid schizophrenic and sent to a psychiatric hospital. Had he not been released at the age of 21 he wouldn't have gone on to murder his mother,  her friend and the six students.

6. At one stage he wanted to be a police officer, but he was rejected because of his huge size. He still made friends with cops by hanging out with them at a bar and was given the nickname Big Ed.
