Welcome to /r/serialkillers!

For the purposes of this subreddit, we use the current FBI definition of a serial killer: TWO OR MORE separate incidents with a cooling-off period in between.

Mass murderers kill two or more people in one incident in one location.

Spree killers kill two or more in one incident in two or more locations without a cooling-off period.

For killers that do not fit the definition of a serial killer, please try /r/allkillers.
