How many people does a serial killer kill?

Answer 1

After 3 similar murders have occurred over a span of more than 30 days with apparent "breaks" or "cooling off" periods in between each murder.

For example, after the 3rd body was found in the Green River in Washington in the 80s, it was officially classified as a serial crime.

It's up to debate as to whether Ed Gein should truly be described as a serial killer. He only admitted to killing 2 women, and was convicted for these two. Law officials believe he may be responsible for other murders in the area. But it goes unproven.

Ed Gein was a regular grave robber, not necessarily a murderer. But his increasingly violent behaviour would have eventually led him to further murders, had he not been so disorganised, which made it easy for investigators to track down their murderer.

Answer 2

A serial killer is a person who murders three or more people over a period of more than thirty days, with a "cooling off" period between each murder, and whose motivation for killing is largely based on psychological gratification.

Answer 3

The FBI defines a serial killer as killed 3 or more victims with a 'cooling off' period in between killings. The cooling off period depends on the individual. In the case of Jack The Ripper the killer murdered twice in one night barely an hour apart. BTK killer Denis Rader's cooling off period would sometimes last two years.

Answer 4

Three, but it cannot be Spree Murders or Mass Murders.

Answer 5

Typically, a serial killer is one who kills two or more people in succession.

Answer 6

The FBI defines serial killer by a person that commits three separate murders with a 'cooling off' period between kills which can be hours or even years but is usually weeks or months.

Answer 7

3 or more on different days
