Well, from what I've read about the Mill Creek Killer, I'd say he's an artist.
The Mill Creek Killer

The Mill Creek Killer (real name unknown) is a narcissistic and necrophilic serial killer who appeared in Season Two episode of Criminal Minds, "The Last Word".


Like his polar opposite, the Hollow Man, a lot remains unrevealed about the Mill Creek Killer, not even his real name. What is known about him is that, at some point in his life, he became a necrophiliac (which he became ashamed of) and developed a sexual preference for brunette Caucasian women. He and the Hollow Man eventually, more or less, began competing with each other in a form of rivalry, as they operated at the same time. They even communicated using personal ads under the aliases "Sunny" and "Holden", references to the novel The Catcher in the Rye.

The Last Word

The Mill Creek Killer is first seen approaching mother Ellen Carroll when she becomes secluded from her family in a bustling park. He catches her attention by stating he lost his daughter and stops her from calling her husband for help. He then pretends to hear his "daughter" move around in the nearby trees and lures Ellen behind a bush, where he punches her hard and drags her away as she dies. He is then seen tending to her corpse before engaging in sexual activities with it off-screen. It is Ellen's disappearance, along with the Hollow Man's latest murder, that brings in the BAU. He is later seen approaching jogger Meredith Dale when she enters a secluded location, killing her and placing her inside his van. He encounters a security guard who inspects the van, but the guard fails to spot the body and he is allowed to go ahead. The Mill Creek Killer later dumps Meredith's body in the woods and it is discovered before he could engage in sexual activities with it. The BAU intends to leave the corpse there so they can wait for the Mill Creek Killer to return and engage in necrophilia with it so they can catch him in the act, but when they apprehend a man who wanders toward the corpse, it is revealed the killer learned of the discovery and sent decoy to trick the authorities.

The Mill Creek Killer attempts to engage in necrophilia with one of his victims.

The Mill Creek Killer later attempts to lure a pedestrian into a secluded area, but the woman refuses, causing him to become violent. She finally realizes that she is about to be abducted and manages to escape him and alert several people nearby, forcing him to flee in a rage. The BAU gets a physical description from the woman, and after they find out about how the two unsubs are communicating, they decide to set another trap for him: get a woman covered in leaves somewhere in the Mill Creek Killer's comfort zone, use the Hollow Man's alias to tell the Mill Creek Killer that he committed a copycat murder, and wait for him to approach the corpse. The ruse works and the Mill Creek Killer is arrested. He later pleads with Gideon to not reveal his necrophiliac activities to the public. When the Hollow Man, enraged at a speech JJ made about him being nonexistent and the murders being merely unconnected, arrives and holds a security guard hostage, he spots the Mill Creek Killer, realizes it is him, and accidentally puts down his .44 Magnum revolver, allowing the authorities to make an arrest.

Reid would later mention the Mill Creek Killer in a seminar on sexual sadism, which Nathan Harris attended.

Modus Operandi

The Mill Creek Killer targeted Caucasian women who were educated and lived in middle-class communities. He would lure them with a ruse, kill them by punching them viciously in the head, and hide their bodies in a ranger district of Mark Twain National Forest that wasn't being patrolled by the rangers, so he could revisit them later. These bodies were hidden under leaves and other debris. During the aforementioned revisits, he would apply makeup, groom their hair, and engage in sexual activities with the corpses.


The Mill Creek Killer is a sexually-motivated offender driven by internal forces and uses blunt-force trauma in order to feel the lives leave his victims' bodies. He spends a lot of time with his victims before and after he kills them. Because his victims willingly follow him in broad daylight, he appears harmless. He would be handsome and have the social skills required to lure his victims. Those who knew him well would be shocked when told that he was the killer. He has been able to get his victims away from their families and friends, making him feel powerful. His ritual of having sex with his victims after killing them has become the most important thing to him; it dominates his thoughts, which provides the privacy he needs. His sexual motivations make him even more predictable, but that does not make it easier for authorities to catch him. Since he is well aware of the patrol schedules of the forest rangers working in the woods where he dumps his victims' bodies, it is possible that he works there himself.

His failure to lure Cara Becker indicates he is becoming irrational and violent in public, which is what the Hollow Man wants. If he does not find a victim soon, he will become even more dangerous. He will even drop his ruse entirely and begin grabbing women at random.

Real-Life Comparisons

"Sex acts with dead bodies are rare occurrences. However, Bundy did it regularly."

The Mill Creek Killer has some resemblance to Ted Bundy (who he was compared to by Morgan, as seen above) - Both were necrophilic serial killers who targeted young brunette women, lured them with ruses, then killed them through manual means (the Mill Creek Killer punched his victims to death, while Bundy strangled and bludgeoned his, and even drowned one), and later returned to the crime scenes in the woods to groom and have sex with the corpses of their victims until the decomposition became too severe.

He is also similar to Sean Vincent Gillis - Both are serial killers who targeted women, engaged in necrophilia with them after killing them, and were active in the same area at the same time as another independant serial killer who also targeted women, with whom they developed a 'rivalry' with.

He is also similar to Lee Roy Martin - Both were necrophilic serial killers who were approximately around the same age when they committed their crimes, both targeted women, lured them both through ruses and brute force, dumped their bodies in wooded areas, engaged in necrophilia with them (once in Martin's case), were both apprehended after abducting (or attempted in the Mill Creek Killer's case) a victim in broad daylight and in the presence of witnesses, and were given a nickname for their crimes. Also Martin reporting his own murders and having a job as a taxi driver is similar to The Hollow Man having the same job and wanting media attention for his crimes.
