Hickey's Trauma Control Model Of The Serial Killer

Hickey (1997), in his trauma control model of the serial killer, argues that various factors can contribute to criminality and in particular to serial homicide. These factors can be biological, developmental, demographic or familial, including childhood trauma (Hickey, 1997, as cited in Miller, 2014, p17). Hickey’s model includes 8 elements – Predispositional factors, Traumatic events, Low self-esteem and fantasies, Increasingly violent fantasies, Trauma reinforces, Facilitators, Dissociation and Homicidal behaviour (Hickey, 2016, p149).

Hickey believes that it is unlikely that any one of these factors alone is responsible for homicidal tendencies but suggests that it can be a combination of factors. He argues that a person is no more likely

He proposes that it is the trauma in conjunction with outside factors such as social or environmental, which exacerbate the problem and leads to the criminal activity (Hickey, 2016, p149). Hickey says that the most common trauma experienced by serial killers is childhood traumatisation caused by rejection and that this rejection can be in the form of rejection by family members or an unstable/abusive home life (Hickey, 2016, p148). Hickey says that rejection by family members, e.g. relatives or parents, is the most common cause of childhood traumatisation and that an unstable, abusive home has been proposed as a major form of rejection (Hickey, 2016, p149). Holmes, Tewksbury and Holmes (1999), in their ‘fractured identity syndrome’ theory of serial murder, suggest that serial killers are similar to everyone else in the early years of personality development and lead normal lives. They argue that an event or series of events that often take place in the serial murderer’s adolescent years, causes a fracturing of the personality and that this fracturing, following subsequent incidents, causes the fracture to explode into a
