Mark Jackson

Mark Jackson is a serial killer who appeared in The Gathering.

Background
Mark was physically abused by his stepfather while he was a child, but when he came out and social services arrived, his mother changed her story to protect her husband. This instilled a deep hatred of women in Mark, who came to believe that all of them were liars. Prior to the events of 'The Gathering', he murdered at least three other women, cutting out their tongues as part of his signature. He started a group that indulged in writing therapy, and would use his group members stories as guidelines for his murders.

Profile
The unsub is a fit, aggressive white male in his mid to late 30s. He's practicing what's called vicarious fantasy assimilation. This refers to the cathartic release that comes when he turns someone else's thoughts or fantasies into reality. He trolls the internet and is selecting women with a strong online presence and who frequently post their fantasies with descriptive detail. There are two levels to his m.o., the first being the enjoyment he gets from taking one of his victim's fantasies and turning it into a nightmare. Once he establishes his dominance by subverting that fantasy, then he moves on to step two, which is removing the tongue. His m.o. is polymorphic. It's taken on different forms while his ritual never changes. It's likely he has already targeted other women.
