This is a feature most often associated with stable intimate relationships. The gang stalkers wish to use one of the partners but the relationship is solid as a rock and their usual method of luring one partner away will not work. This is where the feature of an “out-of-the-blue” suicide will occur in a completely normal, well-adjusted, non-suicidal person.
This will be used for any of the gang stalkers purposes. Whether to set the released party up with one of their own people, perhaps because that person was in a key manipulative position; to release a target from the protection of a relationship to coerce her into prostitution; to mentally destabilise the survivor so that he or she can be directly controlled.
