Hitman

An e-mail is sent to the victim's inbox, supposedly from a hitman who has been hired by a "close friend" of the recipient to kill him or her but will call off the hit in exchange for a large sum of money. This is usually backed up with a warning not to contact the local police or FBI, or the "hitman" will be forced to go through with the plan. This is less an advance-fee fraud and more outright extortion, but a reward can sometimes be offered in the form of the "hitman" offering to kill the man who ordered the original hit on the victim.
