"No, she hurt me. Then she ate me!"
Wallace was one of two twins, the other being named Jesse. Before the two of them turned three years old, Jesse was put up for adoption by their mother Carla when she found raising the both of them difficult. When Wallace was in high school, he stalked a fellow student named Heather Clarke after she broke up with him. Her parents eventually filed a restraining order against him after he began smashing her car with a baseball bat. As a result of the incident, Wallace was placed in and out of multiple institutions for at least a decade, and was diagnosed with acute delusional disorder, apparently inherited from his father, a schizophrenic man named Bill Robbins who was cut out of Carla's life. At some point in his life, he developed a fascination with the praying mantis, especially with the aspect of the females killing and decapitating the males directly after (or sometimes during) copulation before eating the heads, and purchased one as a pet. Prior to "The Inspiration", he moved out of Carla's house and into an apartment, and also received a job as a cook at Wheeler's, a restaurant at a local shopping mall. Upon learning that Heather was about to marry a man, Wallace snapped, tracked her down, and killed her, decapitating her post-mortem and taking her severed head with him. Becoming haunted by recurring hallucinations of Heather as a result, Wallace began killing women who resembled her, fearing that they were out to get him, much like how a female praying mantis would kill a male. He would feed them pieces of Heather's head before killing them.
The Inspiration (Part 1)Edit
After killing two women within three days, Wallace abducts Emma Coleman and takes her to his apartment. He is nearly caught after Corin Todd, a woman who lives downstairs, investigates the noises Emma makes when she begins banging herself on the floor, but Wallace tells her that it is his roommate and a girlfriend having sex. When Corin leaves, he enters the apartment and pulls out a meat cleaver, which he uses to intimidate Emma. Later, Wallace takes her to a forest, where she vomits up a tooth belonging to Heather, which she was force-fed. He then kills her when she yells at him. The following morning, Wallace chats up a female coworker named Mia Rivera, trying to ask her to sit by him at a fountain, but she kindly turns him down, telling him she has a date. Mia then leaves with her boyfriend, while Wallace begins hallucinating Heather's voice talking to him, and he tells her to shut up. The following night, he attacks Mia in her home, force-feeds her with pieces of Heather's head, and then kills her. The next day, Wallace is visited by Carla, who starts asking him questions about Heather's disappearance, which he denies having any involvement in. Then, he hallucinates Carla coughing up a tooth, prompting him to shut the door on her in terror.Wallace later purchases a snake from the mall and feeds it to his pet praying mantis. Then, he hallucinates Heather mocking him, telling him she loved him and would've left her fiancé for him. This prompts Wallace to attack her projection; the noises attract an annoyed Corin, who tries to tell him to stop. However, he threatens her before shutting the door on her. Later, Wallace goes to his workplace, where he is antagonized by his boss Erik Cole and increasingly agitated from serving food to the customers. Finally, he snaps, places several pieces of Heather's head on several foods he is serving, and spies on a number of customers, most of them women. When they all begin to notice that something is wrong with their food, Wallace holds them all, plus his boss, at gunpoint. He begins to hallucinate a taunting Heather being among the customers (even assuming some of their identities) and tries to kill one of them using his meat cleaver as a result, at Heather's urging, but he is confronted by a mall security guard, who orders him to drop the gun. Wallace drops the meat cleaver and fatally shoots the guard before fleeing. By the end of the episode, Wallace is seen at a gas station, about to purchase a drink when he sees a news report about the arrest of a man who is physically identical to him, for the killings. Shocked, Wallace leaves the gas station, just as Hotch cites a quote by Josh Billings, which reveals that it was Jesse who was arrested.
The Inspired (Part 2)Edit
Wallace later drove to his mother's house, hoping to find answers about what he saw in the news report. However, he is suddenly ambushed and knocked out by Jesse. He wakes up tied to a chair in Jesse's house and is interrogated by him about the murders. After telling him what he did and why he did it, Wallace fakes swallowing a sedative given by Jesse and feigns sleep as he unties his bonds. However, upon realizing that Jesse wants to become like him, Wallace decides to stay in the house and agrees to cooperate as long as he doesn't take any more sedatives or be tied up again. While browsing through the channels, Jesse comes across Heather's parents, who beg him to turn himself in while speaking in a news conference. He shuts the TV off and begins hallucinating Heather once more, fleeing outside. He encounters a neighbor named Elizabeth Nash, who mistakes him for Jesse, and when she comments that Jesse isn't like his brother, Wallace flees back inside after projecting Heather onto her. When Jesse returns, he tricks Elizabeth into coming into the house, and Wallace joins him in raping and killing her at Jesse's request.
The two then go on the run, and Jesse asks if there is a place where they can meet with Carla; Wallace tells him to go to St. Mary's Church, the place where Jesse was put up for adoption. They meet Carla there, and Wallace asks Carla for money and a car so they can escape. Carla apparently agrees, and hugs Wallace and kisses his forehead, telling him that she loves him so much that she wants to "eat him". When she begins walking away, inferring Jesse to kill Wallace, Jesse instead grabs Carla, holds her at knifepoint with Wallace's meat cleaver, and threatens to kill her, stating that she abandoned him. Utterly devoted to his mother, and unwilling to believe that Carla wanted him to be killed, Wallace picks up his handgun and threatens to shoot Jesse, ignoring his claims. The twins then begin fighting, and Wallace gains the upper hand before murdering Jesse, just as the BAU storm in. Carla tries to pass him off as Jesse, but Wallace's father Bill is brought to the scene and identifies him as Wallace after seeing his hand tremble (a technique that Bill taught Wallace to counter his hallucinations). Wallace is taken into custody, crying out for his mother as she shakes her head in disappointment.
Wallace initially targeted single blonde women in their 20s, but when he began to devolve, he targeted other women as well. He would abduct them from random locations and take them to his apartment (although he stopped after the murder of Mia Rivera). After tying them up, he would then force-feed them with pieces of Heather's head (with the exception of Elizabeth Nash, who was force-fed her own severed finger), mutilate their genitalia with a meat cleaver (although he stopped after the murder of Mia Rivera), and also rape them. After a while, Wallace would take his victims to the forest, shoot them once in the heart with a 9mm Beretta 92FS pistol, and pose them in a way that they resemble a female praying mantis.
"Get away from me!"
The unsub is a white male aged in his early 30s. Initially, he targeted white, blonde women in their 20s, but he is expanding his victim pool. His M.O. is to rape his victims and then fatally shoot them in the heart. At the disposal sites, he poses them as if they are praying, possibly an attempt to convey a message that only he understands. Before he kills his victims, he forces the women to consume human flesh, known as projected cannibalism. Typically, cannibalism is a willing choice, but the act of forcing someone to engage in it is a form of torture, which means the unsub is sadistic and most likely delusional. The emergence of those delusions would have caused difficulties in his relationships and jobs in the past. He also may have been briefly institutionalized or incarcerated as a result. He sees himself as an enforcer and is punishing his victims for their sins; he also may have an overly developed sense of morality and therefore feels the need to superimpose this on others. He prefers to shoot his victims in the heart, suggesting that he has been hurt by somebody who is clearly the center of his rage. He is devolving rapidly and could resort to even more extreme measures to punish his victims.
It was later realized that based on the rape, force-feeding of pieces of a human head, and superimposing prayer position of the victims, the unsub is obsessed with the praying mantis. The female mantis engages in sexual cannibalism, in which she will decapitate her mate by biting its head off once copulation is complete; this is what the unsub feels has happened to him and also explains why he shoots his victims in the heart. The center of the unsub's anger is a woman who hurt him terribly, and she is all he can think about. He sees his victims as female praying mantises out to destroy him, so before they can get to him, he rapes them and forces them to engage in cannibalism, thus taking away their control of the situation by essentially walking them through the mating behavior of a captive praying mantis, but entirely on his terms. He even mirrors the decapitation of the insect by forcing the victims to eat pieces of a human head, very likely that of the woman the unsub's rage is centered around. At this point, he believes that all women are his enemies and they are out to get him.
The scene of Wallace placing pieces of Heather's head into restaurant meals that are served to unknowing customers seems to be an allusion to rumors that serial killers Fritz Haarmann, Robert Pickton, Karl Denke, Carl Großmann, and Joe Metheny did the same thing.
