Contract killing is a form of murder in which one party hires another party (often called a hitman) to kill a targeted person or multiple people. It involves an illegal agreement between two or more parties in which one party agrees to kill the target in exchange for some form of payment, monetary or otherwise. Either party may be a person, group, or organization. Contract killing has been associated with organized crime, government conspiracies, and vendettas. For example, in the United States, the gang Murder, Inc. committed hundreds of murders on behalf of the National Crime Syndicate during the 1930s and 1940s.
Contract killing provides the hiring party with the advantage of not having to carry out the actual killing, making it more difficult for law enforcement to connect said party with the murder. The likelihood that authorities will establish that party's guilt for the committed crime, especially due to lack of forensic evidence linked to the contracting party, makes the case more difficult to attribute to the hiring party.
Contract killers may exhibit serial killer traits, but are generally not classified as such because of third-party killing objectives and detached financial and emotional incentives. Nevertheless, there are occasionally individuals that are labeled as both a hitmen and a serial killer.
A study by the Australian Institute of Criminology of 162 attempted or actual contract murders in Australia between 1989 and 2002 indicated that the most common reason for murder-for-hire was insurance policy payouts. The study also found that the average payment for a "hit" was $15,000 with variation from $5,000 up to $30,000 and that the most commonly used weapons were firearms. Contract killings accounted for 2% of murders in Australia during that time period. Contract killings also make up a relatively similar percentage of all killings elsewhere. For example, they made up about 5% of all murders in Scotland from 1993 to 2002.
