A serial killer is someone who murders at least two people in separate events that occur at different times, and the murders are carried out in gruesome fashion.
There are most notorious serial killers in the world that you should known :
Jack the Ripper
Jack the Ripper appeared in London’s Whitechapel district in 1888 and murdered five women—all prostitutes—and mutilated their corpses.
Police surmised the killer was a surgeon, butcher, or someone skilled with a scalpel.
Although many suspects have been named over the years, the killer has never been identified.
Jeffrey Dahmer
Jeffrey Dahmer started killing in 1978, just 18 years old, and wasn’t arrested for murder until 1991, after a would-be victim escaped and led police back to Dahmer’s Milwaukee, Wisconsin, home.
It was there that some of the gruesome details of his life of killing were seen via photos of mutilated bodies and body parts strewn across the apartment.
He even had a vat of acid he used to dispose of victims. In all, Dahmer killed 17 people, mostly young men of color. He served time in prison twice—the first time for molestation and the second time for murder—and was killed by a fellow inmate in 1994.
Harold Shipman
Harold Shipman, also known as “Dr. Death,” is believed to have killed at least 218 patients, although the total is quite likely closer to 250. This doctor practiced in London and between 1972 and 1998 worked in two difference offices, killing all the while.
He wasn’t caught until a red flag was raised by several people, including an undertaker who was surprised by the sheer number of cremation certificates Shipman was a part of, along with the fact that most of the cases were elderly women found to have died in bed not at night but rather during the day.
Police mishandled the investigation, and Shipman kept killing until he got greedy and tried to concoct a will for a victim that named him beneficiary, which led the victim’s daughter to become suspicious.
He was finally convicted in 2000 and committed suicide while in prison in 2004.
