When it comes to passing time with some thrill and horror, or quenching the thirst of one’s insatiable curiosity, serial killer documentaries never fail to do the job. With their scary narration, wonderful music effects and cliff-hanging story plots, they just send the chill down your spine that you experience from the horror that they portray. Furthermore, the facts that make them more interesting is that they are actual happenings of human history that have been witnessed taking place, unlike the fantasy horror stories which try to prove “true stories” of white-clothed invisible humans fly by. (Well, you know!)
Here, I have come up with the best five serial killer documentaries that can freak you out of your skin.
(Warning! You might end up smacking the next bearded and garbed-in-all-blue guy, thinking he is a serial killer, even if he is just an innocent postman delivering your son’s parcel to you.)
5. The Milwaukee Cannibal
“The crimes of Jeffery Dahmer made the world cringe. Seventeen murders. Cannibalism. Sex with the dead. A man who made his Milwaukee apartment into a violent and erotic death chamber.”
The documentary starts with these lines that, then, unfold the tale of his monstrosity. Jeffery Dahmer was his name. Records claim that he dismembered 17 boys and men between 1978 and 1991 in Ohio. Through the malignant deeds of necrophilia and cannibalism, he satisfied his urges. Jeffery had sex with the corpses that he murdered. He also cooked body parts of his victims and ate them. The Milwaukee Cannibal was sentenced to life imprisonment, but was killed by an inmate.

4. The Freeway killer
Turmoil happened, when, in South California, mutilated bodies of young men started appearing on a daily basis. No one knew who committed those murders. They termed him “The Freeway Murderer”. 
The former U.S. Air Force aerial gunner William Bonin went on to become one of the most cruel murderers in the history of human jurisdiction, who committed the rape, torture and murder of a minimum of 21 boys and young men in a series of killings between 1979 and 1980. His victims were subjected to his inhuman torture, pedophilia, hebephilia and ephebophilia. Bonin had so much diabolicalness in him that even when in court, he narrated to the parents the gruesome details of how their sons reacted when he tortured them.
The Freeway Killer was executed by lethal injection in 1966.

3. The Sorcerer From Hell
“They believed he could move clouds, grant them wishes and heal them with his magical powers. But, one by one, they began to disappear.”
Imagine walking through a sugarcane field in Indonesia, and suddenly stumbling across half-buried corpses of female humans. It was his ritual to bury women waist-deep with their heads facing towards his house. 
This is the tale of a cattle-breeder from Indonesia, who, as per the books, murdered 42 girls and women in between 1986 and 1997. His name was Ahmad Suradji. This documentary tells the tale of this brutal murderer in a way that will make you hit the ceiling and will send a shiver down your spine at the same time.
