The history of humanity is unfortunately filled with a large number of heinous crimes, murder often being the one that is the most shocking. The term serial killer was first coined in the 1970s, and it is used to describe a person that killed three or more people, usually on separate occasions.
Throughout history, many famous serial killers left their mark on the world. The names such as Ted Bundy, The Zodiac, or Richard Ramirez are enough to make us feel queasy just by mentioning them. However, there is a large number of serial killers that are mostly unknown, but whose crimes are almost as gruesome as the more famous ones.
10. Harrison “Cookie Monster” Graham
This serial killer was arrested in 1987, and police found the remains of seven women in his apartment. At first, Graham tried convincing the police that the bodies were there when he moved in but afterward changed his story to him strangling them by accident during sex under the influence of drugs.
He always slept with a Cookie Monster toy, which was used by his defense on trial to claim that he had multiple personalities. They claimed he had three of them; “Marty,” a friendly handyman, “Frank,” a murderer addicted to drugs, and “Junior,” a child that could not sleep without the Cookie Monster. The court rejected this, and he was sentenced to life behind bars.
9. Amelia Dyer
This British serial killer is also known as the “Ogress of Reading” and was responsible for killing hundreds of young children. She is considered to be one of the most prolific serial killers ever to have lived, although she is mostly forgotten nowadays. She lived in the late 19th century and would promise young women who were not married that she would find homes for their babies.
She would charge them for it, take the babies and then starve or suffocate them to death in her home. Her house was raided in 1896, and police found more than 50 dead children rotting inside, although it is believed that she killed anywhere from 200 to 400 babies. Amelia Dyer was hanged for her crimes.
8. Helen Patricia Moore
Helen Patricia Moore is an Australian serial killer responsible for the deaths of three children and the attempt to murder two more in the 1980s. She killed children she was babysitting, starting when she was 16 years old.
She claims that she killed the children because her younger brother had died, and she was jealous of them for being alive. Her first victim was only 16 months old. She killed her victims by suffocating them. After killing three children and attempting to kill two more, she was arrested and confessed to her crimes.
7. Robert Hansen
Robert Hansen, known as the “Butcher Baker,” was a serial killer known for hunting his female victims for fun through the wilderness in Alaska. He was killing sex workers for his pleasure between 1971 and 1983. His method consisted of capturing his victims, taking them to his cabin, where he tortured them, and eventually letting them go so he could hunt them like animals through the wilderness.
One of his victims, 17-year-old Cindy Paulson, successfully escaped and managed to get to the police; however, Hansen accused her of trying to get money from him, and he was let go. Eventually, the number of the victims started to get too high, and police started paying attention to him again, finally finding evidence that he was the killer. He killed 21 people altogether. He was also sentenced to death and died in jail.
6. Luis Garavito
Luis Garavito is a Colombian serial killer who is known to have killed at least 138 people, although the actual number could be as high as 300. He would promise money and gifts to young boys and lure them to his home, where he tortured and killed them.
The police found the bodies of the dead boys in 1997 in a mass gravesite, where they also found prescription glasses belonging to Garavito. It was easy to connect the glasses to him because of his uncommon eye condition. He was sentenced to 1,853 years behind bars.
5. Patrick Mackay
Patrick Mackay is a British serial killer, famous for his nickname “The Psychopath.” We are off to a great start already! He tried setting fire to a church when he was 13 and ended up in an institution for mentally ill children. However, he managed to get discharged by exploiting a loophole, and his murders began then, nine years later.
He is believed to have killed 11 victims between 1974 and 1975. His crimes were gruesome, and he enjoyed torturing his victims. It was confirmed that he had a personality disorder and was a psychopath. He pleaded guilty to three murders after a trial that lasted only 20 minutes.
4. John Norman Collins
John Norman Collins is responsible for the deaths of eight victims during the 1960s. He is known for murdering coeds, which is an archaic term used for female students. This earned him the nickname “The Original Co-Ed Killer.”
Multiple stab wounds killed his victims, sometimes as many as 47. Some of the victims were even seen with him before getting killed, but there was never enough evidence against him. After several more killings, the police finally managed to tie him with one of the murders by finding bloodstains that matched the blood of the victims in his place of residence. He was found guilty of the crimes in 1970 and is serving life in prison.
3. Charles William Davis
This killer from Maryland worked as an ambulance driver and was responsible for the killing of five women in the 1970s. He was a stalker who followed his victims, waiting for them to stop by an abandoned area. There he would find out their identities by using his connection in the police - his father, and contact the victims and tell them their car lights were left on.
He would then wait for them hidden inside their cars and strange them to death. He would leave the corpses out in open areas along roads where people could find them easily. He was caught after using a credit card that belonged to one of his victims and was sentenced to life in prison.
2. Gary Heidnik
Heidnik is known as one of the more sadistic serial killers that ever lived. He had a schizoid personality disorder. His method of killing his victims is enough to make anyone’s stomach turn.
He would first fill up a pit with water and make his victims stand in it, with the water being up to their necks. He would then use electric wires to electrify them until they would die. After killing them, he would grind their dead bodies in a meat grinder and feed them to his other victims. He was caught and eventually executed in 1999, by lethal injection.
1. Karl Denke
Karl Denke was a serial killer from Prussia who lived in the late 19th and early 20th century. It is believed he killed 31 people, although the real number could be a lot higher. He worked as a butcher in the German town of Münsterberg and was known for selling high-quality meat at the time. Because of World War I, meat was harder to come by, so this was especially strange. In 1924 he was arrested for supposedly attacking a man with an ax.
While in jail, the police let him know that they would search his home, which made him hang himself in his cell. The reason for his suicide was known as soon as they started searching through his house. The police found pots that were filled with human flesh, human bones all over the house, belts that were made from human skin, and body fat in containers that were being used for cooking. It was not hard to conclude that the meat he was selling was made from humans he killed.
