Lonely Hearts Killer

A lonely hearts killer is a journalistic term that refers to a type of killer who lures in victims after contacting them when they post or answer classified or personal newspaper ads. These types of killers are also referred to as want-ad killers or matrimonial bureau murderers.

Motives
Lonely hearts killers have varied motives, but they must fulfill the aforementioned criteria in order for him or her to be classified as a lonely hearts killer. Murders can be involved with robberies gone wrong, elaborate insurance-fraud schemes, sexual violence, or any other pathological impulse. Lonely hearts killers sometimes do not mean to actually commit murder, but were instead forced to resort to it, either by accident or to cover up their tracks. However, other lonely hearts killers, usually serial killers, lure in their victims this way in order to gain easy access to them.
