Ex partner stalking comprises the biggest victim group. It accounts for approximately 60% of all cases. In many of the cases there is a history of domestic violence. Even if there has been no previous history of physical abuse, police should still treat stalking as a domestic violence incident.
Ex partner stalking where there has been previous abuse is the highest risk catagory for assault, rape and murder. Jealousy is another high risk factor. Abusers who have an attitude "if I can't have her no one will" are of serious concern.
There are several issues that make helping ex-partner victims more difficult. If they have left an abusive, controlling relationship then the emotional damage can make it difficult. They are already having to deal with an overwhelming situation and then to add stalking to the mix can be too much.
The other issue is that the stalker knows the victim so well. They know how they think, their routines, who they rely on for support. They know how to manipulate the victim and those around them.
They are also better at stalking. Approximately 50% of abuse victims are being stalked by their partners before they leave the relationship. The abuser will spy on what they are doing online, who they call or text, which websites they visit and who they contact.
In other words, they are an expert on the victim. They use that expertise to spy on, intimidate, humiliate and manipulate the victim.
