Reactor is most common type of killer responsible for 27.1% of murders
It describes someone who sees comments or photos that enrage them
An informer uses Facebook to tell others they intend to kill the victim
Antagonists engage in hostile exchanges that escalate into violence
For fantasists, line between make believe and reality becomes blurred
Meanwhile, a predator creates a fake Facebook profile to lure a victim
Study found 26 out of the 48 Facebook murders had occurred in Britain
Police have so far tracked 48 'Facebook murders' in which killers used social media to hunt their prey or brag about sordid fantasies.
Now UK scientists have identified six personality types that fit into this category in the first-ever study on how the social networking site can affect criminal behaviour.
They believe each killer fits into the profile of either reactor, informer, antagonist, fantasist, predator or imposter.
A reactor is the most common type of killer, responsible for 27.1 per cent of Facebook murders.
It describes someone who sees comments or photos that enrage them on Facebook, and they react violently with deadly force.
THE SIX TYPES OF FACEBOOK MURDERER REVEALED
Reactor - (27.1 per cent of Facebook murders)
A reactor responds to content posted on Facebook by attacking the victim face-to-face. This may be immediately after viewing the content that makes them angry or there may be a time delay in which they revisit the content and ruminate over its meaning.
Informer - (22.9 per cent of Facebook murders)
Uses Facebook to inform others that they intend to kill the victim, that they have killed the victim, or both. Informers use Facebook as a way of demonstrating their control over the victim and the situation.
Antagonist - (16.7 per cent of Facebook murders)
An antagonist engages in hostile exchanges on Facebook that escalate into face-to-face fatal violence. Antagonists may seek to introduce a physical advantage when the conflict goes offline through arming themselves with weapons.
Fantasist - (12.5 per cent of Facebook murders)
These type of murderers use Facebook to perform or indulge in a fantasy. For fantasists, the line between fantasy and reality has become increasingly blurred and the homicide may be a way of maintaining the fantasy or preventing others from discovering the deception.
Predator - (12.5 per cent of Facebook murders)
Creates and maintains a fake profile to lure a victim and meet them offline. May draw upon the information available on the victim's profile to identify and exploit vulnerabilities to establish grounds upon which to develop a relationship.
Imposter - (8.3 per cent of Facebook murders)
Posts in the name of someone else. This could be the victim in order to create the illusion they are still alive or another person to gain access to and monitor the victim's profile.
