Some people are just...born bad. Sometimes the monster is created through extreme abuse or other traumatic circumstances.

But some people...they're just born...wrong. Wires got crosses somewhere in the brain that shouldn't have been crossed and we end up with humanity's most atrocious monsters.

In the summer of 1964 is when Edmund Kemper would commit his first murders.

It was the 27th of August. Edmund and his grandmother, Maude Matilda Hughey Kemper, were sitting at the kitchen table engaged in an argument. Angry, Edmund stormed off into the other room, retrieving the hunting rifle that his grandfather had gifted to him and returned to the kitchen.

Seeing that he had his rifle, Maude asked him not to shoot any birds. However, birds weren't what he had planned on shooting that day. He shot his grandmother three times. First in the head and then twice in the back.

Additionally, in a further fit of rage, he stabbed her repeatedly post-mortem with a kitchen knife. After which he dragged her body from the kitchen into her bedroom.

Then he waited for his grandfather to come from the grocery store. When he stepped out of his vehicle, Edmund shot him to death in the driveway.

Imagine being his mother, whom he called after his grandfather was dead, confessing to what he'd just done. Imagine getting that phone call? What would you do?

His mother told him to call the police. He did so and then waited for them to arrive, where he was then taken into custody. When he was later questioned about the double murder, he told the police that he "just wanted to know what it felt like to kill Grandma."

He also told them that he killed his grandfather so that he wouldn't have to find out that she was dead, and so he didn't have to live without her.

Which, in that sort of mindset, is, in a fucked up kind of way, rather thoughtful.

He was fifteen when he killed his grandparents and was diagnosed as a paranoid schizophrenic. Given this, he was sentenced to the Atascadero State Hospital for the juvenile criminally insane.

Something to consider here...Edmund Kemper has an IQ of 145. Which makes him extremely intelligent. Now given this, while in the hospital there, he not only assisted the doctors in the crafting of the psychological tests the hospital would use, he also memorized the correct answers the no less than 14 of those tests.

This allowed Kemper to completely fool the doctors into thinking that he was sane.

I don't know why they didn't see this coming. What were they thinking? That's what I want to know. Did they think that allowing someone with the IQ of 145 to help create these tests they would use to the damn patients there and NOT expect him to memorize the answers?

If you ask me, they should have been held some kind of accountable to the murders that followed.

Later he freely admitted that he learned quite a lot from the sex offenders that he given the tests to. An example...how it was best to murder the woman after raping her to avoid leaving a witness.

Beginning in May of 1972, he got his next taste of murder. For 11 months, until April of 1973, he killed many young women. Ending with his own mother and her best friend, whom he'd invited over for dinner and a movie.

In the beginning of his murders, he targeted you women hitchhikers that he picked up. Before he actually took the life of his first hitchhiker, he picked up no less than 150 people. However, this was before his murderous and sexual urges, which he called his "little zapples" took him over.

On the 7th of May 1972, Edmund Kemper was in Berkeley where he picked up two 18-year-old students from Fresno State, who were hitchhiking to Stanford University. They were Mary Ann Pesce and Anita Mary Luchessa.

However, they would never make it to Stanford. Instead he took them into a secluded area of woods that is near Alameda. It was a place that he was familiar with from his job with the Highway Department.

Locking Luchessa in the trunk (or boot) of the car, he handcuffed Pesce and both stabbed and strangled them. With both bodies now in the trunk (or boot) of his Ford Galaxie, he returned to his apartment.

Interestingly enough, while he was on his way home, he was pulled over for a broken taillight. He was calm and collected enough that the officer did not suspect anything amiss with him, and he went on his way afterward.

Now while he did have a roommate, they were not home at the time and so he brought their bodies into the apartment and there his "little zapples" ran rampant.

Before their ultimate dismemberment, he took pornographic photos of their bodies, before committed necrophilia. (Sexual relations with a corpse).

Once they were in pieces, he collected them into plastic bags and disposed of them close to Loma Prieta Mountain. Except their heads. He threw their heads into a ravine, however before doing so, engaged once more in sexual fulfillment.

On September 14th, 1972, Edmund Kemper picked up a 15-year-old Korean dance student by the name of Aiko Koo, who had decided to hitchhike to dance class after missing the bus that she would have normally taken.

He drove her to another secluded area with a gun trained on her. Now, by some twist of fate, he ended up accidentally locking himself out of the car, leaving the girl with both his gun and the car keys.

However, instead of taking the car or shooting him through the window or something, fear took over her and she let him back into the car. It was then that he pinched off her nose and covered her mouth, making her pass out. Once she was unconscious, he proceeded to rape and strangle her until she was dead.

He put her body in the trunk of his car and hopped over to a bar to have a few drinks. Before leaving the bar, he took a sneak peak at his prize (I can only imagine the things he was thinking as he looked at her body) before taking her back to his apartment.

Like with his other two victims, he had sex with her body, dismembered, and disposed of her body.

Aiko's mother had already called the police and reported her missing and began putting up missing posters of her little girl.

The day after he murdered this girl, he went up before a board of psychiatrists for a follow-up requirement of his parole.

The first doctor that talked with him determined that he saw no reason to think that Edmund Kemper was a danger to anyone. The second doctor went so far as to use the words "normal" and "safe". Both of the doctors recommended that his juvenile records be sealed in order to aid him in becoming a more well adjusted citizen.

By January 7th, 1973, Edmund was once again living with his mother. That night he was driving around the campus of Cabrillo College when he picked up his next victim. She was an 18-year-old college student by the name of Cynthia Ann Shall, or Cindy to those she knew.

As his M.O., he drove her to a secluded area and shot her to death with a .22 pistol and put her in the trunk of his car. He then drove back to his mother's house where he hid her body overnight in his bedroom closet.

When his mother went to work the next morning, he took her body from the closet, had sex with it, removed the bullet from her body, and dismembered her in his mother's bathtub, before disposing of her body parts over a cliff. (The bad thing about this plan was, the parts washed up on shore pretty quickly.)

Except her head. He held onto her head for many days, and during that time used the head for his sexual desires before he eventually buried her head (facing up) in his mother garden in such a fashion that the head would be looking up at his mother's room.

He would later go on to say that he did this for the reason that his mother "always wanted people to look up to her."

On the 5th of February, 1973, after fighting with his mother once again, Edmund stormed out of the house on the lookout for someone with which to release his fury.

Now, keep in mind that Edmund Kemper, as a fully adult man, is 6'9 weighing more than 250 lbs. These young girls stood no chance against him. Especially with most of these girls being 5'5 or smaller.

By this time, there was a growing suspicion that there was a serial killer targeting hitchhikers in and around the Santa Cruz area, and as such, students were cautioned against hitchhiking or to only get into cars that had university stickers on them. However, they shouldn't have gone that far. They should have stopped at "hey, probably shouldn't hitchhike with anyone..." because Edmund Kemper had such a sticker on his car. His mother was an employee at the UCSC.

He picked up 23-year-old Rosalind Heather Thorpe and 20-year-old Alice Helen "Allison" Liu on the UCSC campus. With them both in the car, he slowly drove through the campus, remarking on how beautiful the view was.

Then he shot them. Thorpe was shot first. When she fell dead against the window, Liu began to panic. The bullet went through her hands that she had put up, as if that alone would stop the bullet(s). He fired at her three times, missing the first two due to her moving around, before landing the third shot into her temple. However, this didn't kill her and as Kemper approached the university gates, he noticed that there were two men stationed there.

However, when they saw the campus sticker on the car, they waved him through. He had wrapped the two women in blankets, so the men had no suspicions to stop him.

He told interviewers later that he had explained to the guard that the girls were drunk and he was trying to get them back to their dorms. Once Kemper drove far enough away from the campus, he shot Lui again, which ended her suffering.

Pulling off onto a cul-de-sac, he put both bodies into the trunk. Before having sex with and dismembering them, Kemper once again removed the bullets from the girl's bodies and drove away from Santa Cruz for disposal. He dumped most of their body parts and then went further away to Pacifica to dispose of their heads and hands.

It was nearly a month later that he killed his mother. He waited all night and as she slept peacefully in her bed he got a hammer from the kitchen (Do most people keep hammers in the kitchen?) and proceeded to her bedroom. It was 5:15 in the morning.

He struck her once, extremely hard with the hammer, and then slit her throat.

After which he proceeded to behead her. He tried to put her larynx down the garbage disposal, however this did not work for him. He took his mother's head and set it on a shelf, where he then screamed at it for the next hour. He used the head as a target to throw darts at and in the end, pretty much smashed the hell out of it.

These murders were motivated by a deep seeded anger and hatred. Especially toward his mother. That was his ultimate revenge on someone he clearly hated.

That same afternoon, after trying to find a way to draw suspicion off of himself once his mother's body was ultimately found, came up with the plan that if someone else was found murdered along with his mother, the police wouldn't focus their investigation on him.

With this plan of action in mind, he invited over his mother's best friend, Sara Hallett, for a surprise dinner for his mother.

When she arrived, her strangled her. First with his hands, and then with the scarf that he had taken from Akio. Removing the woman's clothes, he put her on the bed and had sex with her body. Then he put the body in the closet.

He left a note for the police that read:

"Appx. 5:15 a.m. Saturday. No need for her to suffer any more at the hands of this horrible 'murderous butcher'. It was quick-alseep-the way I wanted it. Not sloppy and incomplete, gents. Just a 'lack of time'. I got things to do!"

He then fled, driving non-stop to Pueblo, Colorado. After not hearing anything on the radio news broadcasts on the murders of his mother and Hallett, he pulled over at a phone booth and made a call to the police.

During this phone call, he confessed to the murders of his mother and her friend, but the police blew him off and told him to call back later. He did just that. Calling several hours later. Asking to speak with an officer that he personally knew, he confessed once again to his latest murders.

Then, like he did when he was 15, waited for the police to come get him. They did and he was placed under arrest. Later he confessed to the killings of the six hitchhikers.

When the cops asked him why he decided to turn himself in he told them, "The original purpose was gone. It wasn't serving any physical or real or emotional purpose. It was just a pure waste of time. Emotionally, I couldn't handle it anymore. Toward the end there, I started feeling the folly of the whole damn thing and at the point of near exhaustion, near collapse, I just said to hell with it and called it off."

During the trial a court appointed psychologist said that Edmund Kemper sliced flesh from the legs of some of his victims, cooked and ate it with macaroni casserole.

On November 8 of 1973, the six-man and six-woman jury deliberated for five hours before coming to the conclusion than he was not only guilty of all counts, but sane.

He himself asked for the death penalty, wanting "death by torture", however, California had a moratorium on executions. He was sentenced to seven years to life for each count of murder, and they were to be served concurrently.

He was sentenced to stay at the California Medical Facility. In July of 2007, 2012, and 2017, he denied himself parole and each time the parole board deemed he was too much of a danger to be returned back into society.

Since he was imprisoned, Edmund Kemper has been in many interviews and documentaries, which have contributed to understanding in the psychological minds of serial killers. It has also helped in the field of criminal profiling.

And FBI criminal profiler John E. Douglas has said of Kemper to be "among the brightest inmates" he had ever interviewed, finding him to be capable of having a "rare insight for a violent criminal."

Kemper talks freely about what he's done and says that he does the interviews to help save other people like himself from killing. At one point he said, "If there's somebody out there that is watching this and hasn't done that - hasn't killed people, and wants to, and rages inside and struggles with that feeling...they need to talk to somebody about it."
