10 Most Evil Serial Killers In History (Notorious & Deadliest)


A Serial killer is a person who murders three or more people, in two or more separate events over a period of time, for primarily psychological reasons. In many cases, the exact number of victims killed by a serial killer is not known, and even if that person is convicted of a few, there can be the possibility that he/she killed much more.

As for what would make a person want to kill multiple other people, often in cruel ways? This question has plagued law enforcement personnel, psychologists, and the general public for decades. Different theories have been proposed as to what triggers someone to become a serial killer – some even suggesting that damage to the frontal lobe of the brain, the part responsible for planning, motivation, and decision-making, may be a trigger for murderous tendencies in a person.

Law enforcement agencies and psychologists have often tried to assess serial killers who have been caught in order to better understand their reasons for acting violently. However, it has been noted by these assessments that most of the Serial killers usually come from dysfunctional families or have had one parent abandon them at an early age.

The following 10 is the list of modern serial killers currently with the highest verifiable murder count, who are non-medical and working alone. Have a look at Top 10 most prolific serial killers in history:
