Serial killer

A serial killer is someone who kills three or more people over a period of time. They usually know their victims and either kill them in one place or travel from place to place to find and murder people. Serial killers usually have a specific type of person they target, such as young women or elderly people, and they often have their own motives, such as revenge or hatred. Serial killers are very dangerous and can cause great harm in a community, so it's important to report any suspicious activity to the police.
