Known as "serial killer groupies" or even "prison groupies", a great number of these women have shown a surprising desire to get connected to the serial killer of their choice. A large number of these women have become directly aligned with these killers, and some have even married or gotten engaged with these criminals.

It is believed that these women are living vicariously through these high-profile criminals, and enjoy the attention and notoriety in the media. Like many other mental conditions, the treatment varies from medications such as Phenothiazine to psychotherapy.

So why are these so-called "groupies" attracted to serial killers? Experts have compiled several reasons why, including:

• Rescue fantasy - The Groupie believes that he or she can change the killer with love and understanding.
• Perfect boyfriend/girlfriend - He or she knows where their criminal lover is at all times (in prison). She can love him without being jealous or having to deal with trust issues.
• Nurturing - Most female groupies have said that they see the little boy in these serial killers and that they want to console and nurture them like a mother would do with her son.
• Drama - Many women and men need to have drama in their lives. They get engrossed in the trial of a serial killer, then an infatuation begins which follows sending letters to the killer.
• Hybristophilia - Sexual arousal of those who commit violent crimes.
• Male figure - Several female groupies have acknowledged that they were raised without a father or male figure, abused and neglected, they look to the serial killer to fill that need.
• Self-esteem - Some women have very low self-esteem and believe that they can't find a man. Since these killers are in prison and lonely themselves, those women will target them for attention and a fantasy relationship.
