There are real - life contract killer stories that are true. But it's important to note that the information we get might be distorted. Some killers might boast or lie about their deeds to gain a certain reputation. But real investigations and court cases do reveal the existence of such a dark profession. For example, the case of Charles Harrelson, father of actor Woody Harrelson, who was convicted of being a contract killer in a high - profile murder case.
Yes, some are based on true events. There have been cases in history where people were hired to kill others for various reasons, like in organized crime syndicates. For example, the story of Richard Kuklinski, also known as 'The Iceman'. He claimed to be a contract killer and was involved in many underworld activities. His story involves a lot of violence and shows the seedy underbelly of criminal contract killing.
