Ben Foster

"C-Can you make them stop, please?" "Th-There's no one there!" "They're right there!"

Ben Foster is a schizophrenic spree killer (and, at one point, an arsonist) who appeared in Season Six of Criminal Minds.

Background
Ben was born suffering from schizophrenia and kept seeing imaginary friends. His mother, a strict Christian, believed he was possessed by demons and took him to a local church for an exorcism. The exorcism "worked" for a short time, and Ben befriended three of the people who performed the exorcism, Matt, Tony, and Yolanda, but something happened that caused him to set a fire that killed them (what happened is never specified). Ever since, Ben began hallucinating about the three of them and was pressured by them to kill Jay Johnson, a disc jockey.

Ben is first seen shopping at a supermarket with Matt and reunites with Tony and Yolanda. As a clerk begins scanning his food, Ben spots Karen Heywood and tries to talk to her but is rebuffed. Matt, Tony, and Yolanda force Ben into following Heywood to her house and killing her. He later hallucinates Tony fixing his sink and he states that he doesn't want to kill anymore but is scolded by them. The following night, his hallucinations force him into killing another man. At the same time, the BAU arrives at Portland. Knowing he is unable to control his hallucinations, Ben attempts to go get another exorcism, but, as they aren't performed anymore, he is turned down and goes aboard a bus. There, Matt, Tony, and Yolanda pressure Ben into following a female passenger off of the bus and kill her at her home. Ben does so, and later, the BAU realize from the overkill of all of the victims that Ben is stabbing them repeatedly so he can sleep, which allows his hallucinations to go away. Ben later hallucinates that he is killing Matt, Tony, and Yolanda, but they stand back up, "alive".

The BAU and local police later track down Ben at his home, and he and Matt, Tony, and Yolanda flee to a neighbor's house where Ben takes two children hostage. The BAU arrive inside the home and convince Ben to release the children after Hotch tells him that Matt, Tony, and Yolanda are dead, therefore being unable to hurt him anymore. Morgan then tells him that it was going to be okay and promising to get him a doctor's help. However, Ben hallucinates Reid ordering him to stab him in the neck alongside Matt, Tony, and Yolanda (stating that his problems will all go away if he does so), and, as a result, he is non-fatally shot by Hotch when he tries to do so. Ben is put into an asylum, where he continues to hallucinate despite the electroshock therapy that was supposed to remove them. Ben asks them why they are there and they respond with that they "have been there his whole life". Ben tells them that he's only seen them since the church fire and they retort with, "Are you sure about that Ben?" The screen then fades to him on his mother's lap at the age of five, with three shadowy figures moving around.

Modus Operandi
Ben killed Matt, Tony, and Yolanda with a fire, but it is unknown how he set it. The 2011 killing spree he committed was completely disorganized as a whole, with the acts being mostly unplanned in advance. He killed his victims at their homes, except for Jay Johnson, who was killed in an alleyway. He would bludgeon them with a blunt object he brought along, but in the murder of Karen Heywood, he would use any blunt household item that caught his eye. He would also stab his victims repeatedly even after death so then he could be able to tire himself out and sleep in order to escape his hallucinations. After the murder of the old woman, he would only use a knife against his victims. In the murders of Johnson, Heywood, and presumably Joe, Ben would also steal several belongings and sell them for money for his medication.

Profile
The unsub is a white male and a paranoid schizophrenic who suffers from hallucinations. He probably lives nearby and is in his early 20s, as that is the typical age when schizophrenic breaks occur. He is hyper-vigilant, and in this condition, he is unable to travel far from his home. He kills at night, and he is very violent. However, during the day, he is probably a loner and cannot keep a job. Something probably happened to this unsub in his childhood, as childhood voices are telling him to kill (or he is misinterpreting them as doing so). The unsub has probably been coping until now, but a recent stressor is causing him to act out. He will spend his days wandering around, fighting the desire to kill, yet he feels trapped by his hallucinations. No matter what he does or tries to do, the hallucinations' power is greater than his own. Because of his limited social circle as a child, it is believed the incident involved close friends or family. After finding out the stressor and the recent incident causing the unsub to relapse, it will be that much easier to deduce his identity. He strikes at night and will not retreat until found. The unsub also has insomnia, which make his hallucinations clearer when he is awake, leaving sleep to be his only escape. The way the unsub stabs and bludgeons the victims more than at least 30 times suggests that he would tire himself out and fall asleep, giving him some relief from the hallucinations.

Real-Life Comparisons
Ben is somewhat similar to serial killer Herbert Mullin in the sense that both were paranoid schizophrenics and they attempted to stop killing by going to a priest. The difference in the latter similarity was that Ben didn't kill the priest like Mullin did, though it can be initially assumed he did until after his murder of the old woman. Also, Ben's habit of robbing his victims and selling the items seems to be a reference to the Dnepropetrovsk maniacs, who also robbed their victims and sold the belongings, though their motivations for doing so are entirely different. Additionally, as a reference to the maniacs, it was originally thought that Ben's murders, all of which were extremely violent and random, were committed by a group of thrill killers, instead of just one severely psychotic individual.

Ben's crimes may have also been indirectly inspired by the Briley Brothers, a group of criminals that also committed a spree of brutal murders and robberies, which incorporated in their M.O. stabbing and bludgeoning with a wild variety of items (some of which were conveniently at the crime scene). Additionally, the Briley Brothers consisted of four members (the three brothers and an accomplice), which could be a reference to the fact that Ben had three imaginary accomplices who were initially assumed to be real in the episode.
