Michael Lee Peterson

"See all those people out there?! Huh?! They're all gonna know me!"

Michael Lee Peterson was a copycat serial-turned-spree killer and budding serial rapist who appeared in Season Eleven of Criminal Minds.

Background
Michael was born in Joliet, Illinois, to Vincent and Lorraine Peterson and was raised in a poor household. Vincent was later sent to prison for two counts of armed robbery and served most of his sentence at Stateville Penitentiary, where mass murderer Richard Speck and serial killer John Wayne Gacy were also imprisoned. Michael and Lorraine visited Vincent every weekend, and during those visits, he observed the inmate hierarchy, in which serial killers would be at the top in terms of respect while snitches and pedophiles were at the bottom. It was also presumed that he may have seen Speck during some of the visits, and possibly even interacted with him, judging by Michael's conversation with the boy. These observances triggered a deep fascination of serial killing, as well as a passion for extreme thrill-seeking and a desire to gain the respect his father never got. In March 2005, Vincent was transferred out of Stateville Penitentiary and into Regan Penitentiary for his own safety, after he was stabbed repeatedly and nearly killed when he was about to testify against his partner-in-crime. Michael later started picking fights at school, resulting in him being expelled from four different schools. On November 7, 2006, Lorraine, who raised Michael alone for most of his life, died of a stroke.

In 2010, Michael got a job as a deckhand for a crab-fishing vessel, allowing him to easily seek out thrills due to the dangers of the job. When his father died in 2014, he took advantage of his job to begin serial killing in different countries. For his crimes, he chose to emulate the M.O.s of the most infamous serial killers of the past, as a way to seek out more thrills through the pressure of being actively sought by the public. His first murder occurred on September 12, 2014, at Rostov, Russia, where he raped, mutilated, and killed a girl named Natasha Dudechenko in an emulation of the M.O. of Andrei Chikatilo, "The Rostov Ripper". Michael was spotted at the crime scene by Russian police, but he managed to escape before they could apprehend him. In March 2015, Michael arrived at London, England, and began killing prostitutes in the Whitechapel area, as an emulation of Jack the Ripper. Interpol became aware of the murders and assisted investigators in tracking Michael down, with Emily Prentiss taking supervision of the joint investigation. Prentiss eventually got the idea of luring Michael out with an undercover officer and selected Detective Inspector Louise Hulland for the job, despite the higher-ups' disapproval to the idea. However, the operation failed, resulting in Louise's murder and Michael's escape. The botched operation has since traumatized Prentiss.

"Who's next? You? You. Decisions, decisions! ...You win, rich girl!"

Michael is first seen in Prentiss' flashback about the undercover operation. In the middle of the operation, Prentiss came into the warehouse to rescue Louise. Once she found her, badly wounded from multiple stab wounds, Michael appeared and incapacitated Prentiss. Prentiss grabbed her handgun and shot at Michael, but he was protected by a bulletproof vest. He started to laugh at Prentiss' attempts to kill him before escaping. Louise died from her injuries afterward. In the present, Michael returned to the U.S. and continued to commit more murders in 2016. First, he emulated the Boston Strangler's M.O. in Boston in August. A month later, he proceeded to the Bronx, New York City, to emulate David Berkowitz. His emulation of Berkowitz's first shooting alerts Prentiss, who calls in the rest of the BAU to help her in the investigation. Michael is then seen in his hotel room cleaning up his bloodied clothes in the sink. Afterwards, he goes to the main room, where he listens in on a Discovery Channel episode about the life cycle of salmon. He sits on the bed, grabs his revolver, and opens it. Then, he grabs a bullet, puts it in his mouth, and plays around with it. Afterwards, he takes it out, puts it in the gun, closes the chamber, and lies down on the bed. Meanwhile, Monica DeJesus, who was shot in the leg by Michael but left alive by him as part of the emulation, is interrogated by Prentiss and JJ, and provides a composite sketch of Michael.

The following night, Michael spots a wealthy couple, Trent and Rhonda Klein, in Queens. Whipped into a frenzy by their affluence, he kills them in an emulation of elements of Berkowitz's second and sixth shootings. When he is spotted by police entering the warehouse a block away, the BAU is informed, but they miss him and instead arrive at the scene of the Kleins' deaths, which frustrates Prentiss. Later, Michael returns to his hotel room, where he is seen packing up his gear and then leaving. Then, he travels back to Chicago by taking a bus. During the bus ride, Michael is reading a book about America's most infamous killers. Just then, he notices a boy sitting across from him staring at him and trying to read the book, and he tells him that it is not polite to stare. Michael then starts talking to the boy and gives him a bullet, which he claims is lucky because it doesn't have the boy's name on it. The next morning, the bus arrives in Chicago in a bus depot. The passengers start to get off the bus and the boy tries to give Michael back the bullet, but he tells him to be quiet, keep the bullet, and not to tell his mother about their conversation. The boy hides the bullet from her and they both leave the bus. Before the boy gets off, Michael says goodbye to him by imitating a gun being fired and the boy does the same thing.

After Michael leaves the bus, he goes to Northeast State University in nearby Evanston with the intention of emulating Richard Speck's attack on a townhouse. He wanders around and eventually approaches a student named Megan Ross, striking up a friendly conversation with her. He pretends to be a new professor and asks where Mason Hall, a sorority dormitory, is, claiming to be meeting an assistant there. All the while, he eyes Megan's jewelry, and when she leaves, he frowns bitterly at her. The following night, at Mason Hall, Megan's roommate Charlotte comes into her room and tells her about a serial killer that the FBI is looking for. When shown a wanted poster with Michael's photo, Megan is shocked and tells Charlotte about her earlier encounter with him. They both call the FBI hotline but are interrupted by Michael, who steps inside the room and orders Megan to put the phone down, which she does. He then takes both girls hostage and forces them to another room. When a student named Kasey answers Megan's knocks and opens the door, Michael takes her hostage as well. Once everyone is inside the room, Michael kills Kasey. Afterwards, he drags Kasey's body to another location. Megan takes advantage of Michael's distraction to grab a nearby pair of scissors. Michael then reappears and holds both girls at gunpoint, taunting them and asking out loud who he should kill next.

Eventually, Michael chooses Charlotte, but when he is about to kill her, Megan stands up, yells at Michael to let her go, and tries to stab him with the scissors. However, he grabs her arm and stops her, but both girls manage to hold onto Michael's arms, which causes his revolver to go off. The BAU, having just arrived at Mason Hall, are alerted to Michael's location by the gunshots. Charlotte bites Michael's arm, which causes him to drop his revolver. Then, in a fit of rage, he throws Charlotte onto the bed and subdues Megan by throwing her against a picture frame, causing her to drop the scissors. Charlotte manages to escape, finds the BAU, and tells them that Michael is going to kill Megan. Prentiss, JJ, and Rossi step inside the room, as Michael holds Megan at gunpoint. Though he threatens them that he will kill her if they come close, Prentiss steps forward and reminds Michael about their encounter in London. This surprises Michael, who comments that she followed him all the way to the U.S. She then adds that police agencies all over the world are looking for him. The agents then try to talk him down by telling him that he will be all over the news if he surrenders. Embellished by this, Michael starts ranting about how they are going to write books about him and how everyone in the world will know about him. When he turns his head towards the window to observe responding police officers, still ranting, Prentiss shoots Michael through the side of the forehead in mid-sentence, killing him instantly.

Modus Operandi
As Michael copied the M.O.s of infamous serial killers, he killed his victims through a variety of means, such as strangulation, throat slashing, and shooting. In the case of Natasha Dudechenko, he raped her to emulate the sexual assault Andrei Chikatilo performed on his victims, most notably nine-year-old Lena Zakotnova. He originally went out of his way to emulate the original murders, but became increasingly less focused as he channeled his rage towards people of affluence. By the time he attempted to emulate Richard Speck during the attack on Mason Hall, he ignored the more important aspects of Speck's M.O.: he targeted college students at a sorority dormitory instead of nurses at a townhouse, staged his attack in the northern and more affluent side of Chicago instead of the southern side, shot his victims instead of stabbing or strangling them, apparently had no intention of raping or torturing his victims, and attacked three victims instead of eight (likely because it was the most reasonable number of potential victims he could achieve)

His signature was loitering at the scenes of the killings so he could be spotted by responding police officers and get a rush out of narrowly escaping them. He would always kill his victims between the months of March and September since he would be busy working as a deckhand between October and February.

Profile
"They're gonna write books about me! I'm even gonna make you famous..."

The unsub is a narcissistic copycat killer. While most copycats emulate other murderers due to either low self-esteem, identity issues, or low confidence, this unsub is different as he has high confidence in himself. He is brazenly copying high-profile murders and he is currently doing locally. The fact that he is only active between the months of March and September means he has a way to make money between the months of October and February in order to finance his crimes; it is probably a cash business occupation so he does not leave a paper trail. Given his particular skill set, he is likely a thief, drug dealer, or a member of an organized criminal organization. He is extremely mobile, so he may be going to an airport, train station, or bus station that could take him to the location where he will kill next. His fascination with serial killers is deeply embedded in his psyche and is part of what drives him, meaning he was exposed to the subject at a young age. He may be a victim who survived, related to a victim who survived or was killed, or even connected to a perpetrator.

Real-Life Comparison
Outside of his copycat killings, Michael's habit of charming his female victims, as well as his devolution and attack on a sorority house, seem to be based on Ted Bundy, who did the exact same things.
