On 11 June 1981, he invited fellow Sorbonne classmate, Renee Hartvelt, over to his place for dinner. He had carefully selected her for her qualities and hoped that by killing and eating her, he would ‘absorb her energy’ and replace his own inadequacies. Sagawa shot Dutch-born Hartevelt in the neck with a rifle. He feasted on her body for two days.

The French police caught him when he tried to dispose of what was left of her remains. In France, Sagawa was deemed unfit to stand trial and was detained in a psychiatric institution indefinitely. He was eventually deported back to Japan, where he was immediately committed to Matsuzawa hospital.

They declared him sane and stated that the sole motivation for his crimes was sexual perversion. A cruel twist in the law meant that the charges were dropped in France and the documents sealed without the Japanese authorities ever seeing them. This meant that they could not legally detain Sagawa in Japan. In 1986, he checked himself out of the hospital and remains free to this day.

Andrei Chikatilo. PA Photos Ukrainian born Chikatilo murdered, mutilated and sexually assaulted 52 women and children between 1978 and 1990. In 1978, in the coal-mining town of Shakhty, 9-year-old Yelen Zakotnova became Chikatilo’s first murder victim.

He strangled and stabbed the child, attempted to rape her, and then dumped her body. After this first murder, the previously impotent Chikatilo realised he could achieve sexual arousal and orgasm through violence. That realisation compelled him to strangle, stab and mutilate his victims in a 12-year orgy of terror. The increasing number of murders sparked a massive police operation. Chikatilo was arrested after his final victim, 22 year-old Svetlane Korostik, left a bite mark on his finger.

That evidence, along with blood and semen samples confirmed that the police had their killer. Chikatilo confessed to 34 out of the 36 murders he was charged with. He later confessed to a further 22 killings. Perhaps most chilling of all, Chikatilo confessed to chewing on the extracted uteri of his female victims and the testicles of his male victims, then discarding the body parts later. Chikatilo was found guilty of 52 murders and five sexual assault charges. He was sentenced to death and executed on 14 February 1994 by a single gunshot behind the right ear. Jeffery Dahmer.

Growing up, Dahmer had an unhealthy obssession with dead creatures and dissection and was considered a loner and oddball by his peers. Aged 18 and just three weeks after his high school graduation, Dahmer committed his first murder. He picked up 18 year-old hitchhiker Steven Mark Hicks then lured him back to his house with the promise of alcohol. But when Hicks said he wanted to leave, Dahmer bludgeoned him with a 10lb dumbbell. He went on to strangle him with the bar of the dumbbell, then stripped him and masturbated over his corpse.

Later, he pared the flesh from his bones, He dissolved the flesh with acid and crushed the bones with a sledgehammer. Over the next 13 years, Jeffrey Dahmer’s reign of terror would claim the lives of 17 boys. Most of his victims were killed by strangulation after being drugged with a sedative.

To satisy his sexual urges, Dahmer needed to keep his victims submissive. He would bore holes into their skulls and inject muriatic acid or boiling water directly onto the brain, rendering them zombies.

Dahmer would eviscerate his victims and store their body parts for later consumption By 1991, Dahmer was murdering one person a week. On 22 July of that year, all that ended. Tracy Edwards escaped from Dahmer’s apartment and alerted the police.

In total, Dahmer’s house of horrors was home to a severed head, three bags containing a heart, flesh and a portion of muscle. A freezer contained three heads, a human torso, a bag containing flesh and some internal organs.
