On average, the Federal Bureau of Investigations in the United States and the Metropolitan Police in England investigate fewer than 100 cases of contract killings each year.
Most of the cases in the two countries are related to gang activities, with the occasional case involving spouses looking to kill their partner for insurance collections.
The contract killers selected for these jobs are usually first-time killers who have been involved in other lower level criminal activities.
The reported price paid to these types of contract killings are between a few hundred dollars to $25,000.
