Ted Bundy kept victims' heads as trophies after having sex with decapitated corpses

For more than 40 years Ted Bundy's long-term girlfriend has kept her silence.

Elizabeth Kendall has revealed very little about her time with one of the world's most infamous serial killers.

But now, in a new Amazon documentary Ted Bundy: Falling For A Killer she lifts the lids on what life with the murderer was really life.

Elizabeth was the one who finally gave Bundy's name to the police but she insists that for years she was unaware he was the one behind the gruesome crimes.

Her daughter, Molly, who also knew the rapist and killer, will also give her experience of her time with Bundy.

Amazon says the documentary looks at Bundy's crimes from a "female perspective" and Elizabeth will reveal what Bundy the man, not the murder, was like at home.

She said: "I fell in love with him from day one but there were all these coincidences and I couldn't let it go."

Elizabeth was ultimately the person who gave Bundy's name to police and he was finally arrested and locked up, ending his reign of terror.

But during his terrifying killing spree throughout the 1970s Bundy is believed to have killed up to 100 women.

It made him America's most prolific serial killer - and his choice of 'trophy' from each victim was also extreme.

Many serial killers choose to keep something from their victims but Bundy, who described himself as “the most cold-hearted son of a bitch you’ll ever meet” was truly sadistic.

His MO saw him mainly bludgeon his victims to death before he spent the night with their dead bodies.

In many cases he would then cut off their heads with a hacksaw and take it back to his apartment as a momento.

Once he got his trophies home Bundy would carry out sick acts, like washing their hair and applying make-up before he would perform sex acts on them.

And the murderer had a chilling reason for wanting to take the heads home with him.

He said: "When you work hard to do something right, you don’t want to forget it.”

After being convicted of 36 murders, which he confessed to, Bundy was put to death in January, 1989.

But he hinted he had been responsible for far more deaths.

When asked by federal agents how many women he had really killed, claimed: “Add one digit to that, and you’ll have it.”

Bundy started his killing spree when he was a clean cut law student back in 1974.

He had no criminal record and even worked for a suicide prevention hotline.

There was nothing linking him to the soaring number of women who had gone missing.

It's thought he carried out his first gruesome crime on January 4, 1974, when he broke into the basement bedroom of an 18-year-old student, battered her with a metal rod until she was unconscious before sexually assaulting her with the same object.

His victim was left permanently brain damaged and was in a coma for 10 days following the attack.

But it seemed Bundy developed a thirst for the brutality of what he had done and just a month later commited his first murder.

He broke into another student's flat, Lynda Ann Healy, knocked her out, dressed her and carried her out to her car.

She was never seen again but a partial fragment of her skull was found in the place where Bundy dumped many of his bodies.

Bundy used the same pattern with virtually all of his victims, who were almost always female students or young girls.

One of the tactics he used to get them close to his car was to wear a fake cast and ask them to help him carry something.

As they did, he would hit them until they were unconscious, bind, rape and then kill them before dumping their body in a remote place in the woods.

Chillingly, Bundy would often spend the night with the corpses of those he had killed and would return again and again to have sex with their dead bodies.

He only stopped when they were too decomposed or had been eaten by animals.

Bundy also used to pose the victims into styles he had seen in porn when he was a child and take Polaroid snaps so he could look at them again and again.

In a further gruesome confession, Bundy even admitted to eating parts of his victims' bodies so he could "possess" them and they would become part of him.

The killer claimed he was addicted to murder, saying: "You feel their last bit of breath leaving their body. You’re looking into their eyes. A person in that situation is God!”

Finally, the net started to tighten around Bundy when several women came forward to say they had been approached by a man called 'Ted'.

Three of them, including one of his ex-girlfriends, even told officers he was the one responsible but police refused to believe someone like him could be behind the disappearances.

Bundy then moved to Utah after winning a place at law school, but his murder spree didn't end.

His first victim was a hitchhiker, who he raped, strangled and then dumped in a river, before going back to next day to take pictures of her body and to cut her up.

Nancy Wilcox was just 16 when she was raped and strangled in Salt Lake City before her remains were buried.

A month later Melissa Anne Smith, the 17-year-old daughter of a police chief in Salt Lake City disappeared after leaving a pizza parlor.

Her body was found nine days later, with a postmortem indicating she may have remained alive up for to a week following her disappearance.

Sickeningly, Bundy later described how he treated murder like a sport, and would actually engage in a catch and release type of training during his “off season”, when he would pick up women simply to keep his skills sharp, and then let them go.

And he seemed to take just as much pleasure in running rings around the police with what he believed was his far superior intelligence.

In 1975 he was arrested for kidnapping Carol DaRonch, one of the few who survived his attacks, and jailed for 15 years.

Just two years later, while acting as his own lawyer after being indicted over the death of a Colorado woman, he jumped out of the jailhouse library window and disappeared.

He was caught eight days later but in December the same year, 1977, he climbed out of a hole in the ceiling of his cell and fled to Florida, where he picked up his murder spree where he had left off.

It was then that his killings really stepped up a notch.

In January 1978 Bundy broke into he Chi Omega sorority at Florida State University and raped and killed four women in just 15 minutes.

First, he bludgeoned 21-year-old Margaret Bowman to death with a chunk of firewood then parroted her with a stocking, then beat and strangled 20-year-old Lisa Levy before sexually assaulting her with a bottle, ripping one of her nipples and leaving a deep bite in the flesh of her buttocks.

He then bludgeoned death two other students, Karen Chandler and Kathy Kleiner, who were sleeping in an adjoining bedroom.

His last known killing was 12-year-old Kimberly Leach, who his kidnapped from school, raped, murdered and then dumped her body under a pig shed.

A few days later Bundy was finally arrested because his Beetle was stolen.

After confessing to 36 murders, Bundy was jailed and it has been reported that he was repeatedly raped by four men while he waited for execution on death row.

When the day of his execution came there were huge crowds outside, screaming 'brun, Bundy, burn'.

He was put to death in the electric chair.

Eleanor Rose, the mother of one of his victims, Denise Naslund, said: “For everything he did to the girls - the bludgeoning, the strangulation, humiliating their bodies, torturing them - I feel that the electric chair is too good for him.”
